There is a knack in the successful handling of plants that it is impossible to describe in print. All persons can improve their practice through diligent reading of useful gardening literature, but no amount of reading and advice will make a good gardener of a person who does not love to dig in a garden or who does not have a care for plants just because they are plants. To grow a plant well, one must learn its natural habits. Some persons learn this as if by intuition, acquiring the knowledge from close discrimination of the behavior of the plant. Often they are themselves unconscious of this knack of knowing what will make the plant to thrive; but it is not at all necessary to have such an intuitive judgment to enable one to be even more than a fairly good gardener. Diligent attention to the plant’s habits and requirements, and a real regard for the plant’s welfare, will make any person a successful plant-grower. Some of the things that a person should know about any plant he would grow are these:—
Having suited the situation to the plant, and having prepared the ground well and made a resolution to keep it well, special attention must be given to such matters as these:—
Prepare the surface earth well, to make a good seed-bed. Plant when the ground is moist, if possible, and preferably just before a rain if the soil is of such character that it will not bake. For shallow-planted seeds, firm the earth above them by walking over the row or by patting it down with a hoe. Special care should be exercised not to sow very small and slow-germinating seeds, as celery, carrot, onion, in poorly prepared soil Land may be prevented from baking over the seeds by scattering a very thin layer of fine litter, as chaff, or of sifted moss or mold, over the row. A board is sometimes laid on the row to retain the moisture, but it must be lifted gradually just as soon as the plants begin to break the ground, or the plants will be greatly injured. Whenever practicable, seed-beds of celery and other slow-germinating seeds should be shaded. If the beds are watered, be careful that the soil is not packed by the force of the water or baked by the sun. In thickly sown seed-beds, thin or transplant the plants as soon as they have made their first true leaves. For most home-grounds, seeds may be sown by hand, but for large areas of one crop, one of the many kinds of seed-sowers may be used. The particular methods of sowing seeds are usually specified in the seed catalogues, if other than ordinary treatment is required. The sled-markers (already described, p. 108) open a furrow of sufficient depth for the planting of most seeds. If marker furrows are not available, a furrow may be opened with a hoe for such deep-planted seeds as peas and sweet peas, or by a trowel or end of a rakestale for smaller seeds. In narrow beds or boxes, a stick or ruler (Fig. 115) may be used for opening creases to receive the seeds. The depth at which seeds are to be planted varies with the kind, the soil and its preparation, the season, and whether they are planted in the open or in the house. In boxes and under glass, it is a good rule that the seed be sown at a depth equal to twice its own diameter, but deeper sowing is usually necessary out of doors, particularly in hot and dry weather. Strong and hardy seeds, as peas, sweet peas, large fruit-tree seeds, may be planted three to six inches deep. Tender seeds, that are injured Many common plants are propagated by cuttings rather than by seeds, particularly when it is desired to increase a particular variety. Cuttings are parts of plants inserted in soil or water with the intention that they shall grow and make new plants. They are of various kinds. They may be classified, with reference to the age of the wood or tissue, into two classes; viz. those made from perfectly hard or dormant wood (taken from the winter twigs of trees and bushes), and those made from more or less immature or growing wood. They may be classified again in respect to the part of the plants from which they are taken, as root-cuttings, tuber-cuttings (as the ordinary “seed” planted for potatoes), stem-cuttings, and leaf-cuttings. [Illustration: Fig. 122. The planting of the dormant-wood cuttings.] Dormant-wood cuttings are used for grapes (Fig. 122), currants, gooseberries, willows, poplars, and many other kinds of soft-wooded trees and shrubs. Such cuttings are ordinarily taken in fall or winter, but cut into the proper lengths and then buried in sand or moss where they do not freeze, in order that the lower end may heal over or callous. In the spring these cuttings are set in the ground, preferably in a rather sandy and well-drained place. [Illustration: Fig. 123. Carnation cutting.] Usually, hardwood cuttings are made with two to four joints or buds, and when they are Cuttings of currants, grapes, gooseberries, and the like may be set in rows that are far enough apart to admit of easy tillage either with horse or hand tools, and the cuttings may be placed 3 to 8 in. apart in the row. The English varieties of gooseberries, considerably grown in this country, do not propagate readily from cuttings. After the cuttings have grown one season, the plants are usually transplanted and given more room for the second year’s growth, after which time they are ready to be set in permanent plantations. In some cases, the plants are set at the end of the first year; but two-year plants are stronger and usually preferable. Root-cuttings are used for blackberries, raspberries, and a few other things. They are ordinarily made of roots from the size of a lead pencil to one’s little finger, and are cut in lengths from 3 to 5 in. long. The cuttings are stored the same as stem-cuttings and allowed to callous. In the spring they are planted in a horizontal or nearly horizontal position in moist sandy soil, being entirely covered to a depth of 1 or 2 in. [Illustration: Fig. 124. Verbena cutting.] Softwood or greenwood cuttings are usually made of wood that is mature enough to break when it is bent sharply. When the wood is so soft that it will bend and not break, it is too immature, in the majority of plants, for the making of good cuttings. [Illustration: Fig. 125. Leaf-cutting.] One to two joints is the proper length of a greenwood cutting. If of two joints, the lower leaves should be cut off and the upper leaves cut in two so that they do not present their entire surface to the air and thereby evaporate the plant juices too rapidly. If the cutting is of only one joint, the lower end is usually cut just above a joint. In either case, the cuttings are usually inserted in sand or well-washed gravel, nearly or quite up to the leaves. Keep the bed uniformly moist throughout its depth, but avoid any soil which holds so much moisture that it becomes muddy and sour. These cuttings should be shaded until they begin to emit their roots. Coleus, geraniums, fuchsias, carnations, and nearly all the common greenhouse and house plants, are propagated by these cuttings or slips (Figs. 123, 124). Leaf-cuttings are often used for the fancy-leaved begonias, gloxinias, and a few other plants. The young plant usually arises most readily from the leaf-stalk or petiole. The leaf, therefore, is inserted into the ground much as a green cutting is. Begonia leaves will throw out young plants from the main ribs when these veins or ribs are cut. Therefore, well-grown and firm begonia leaves are sometimes laid flat on the sand and In the growing of all greenwood and leaf-cuttings, it is well to remember that they should have a gentle bottom heat; the soil should be such that it will hold moisture and yet not remain wet; the air about the tops should not become close and stagnant, else the plants will damp off; and the tops should be shaded for a time. In order to control all the conditions, such cuttings are grown under cover, as in a greenhouse, coldframe, or a box in the residence window. [Illustration: Fig. 126. Cuttings inserted in a double pot.] An excellent method of starting cuttings in the living room is to make a double pot, as shown in Fig. 126. Inside a 6-in. pot set a 4-in. pot. Fill the bottom, a, with gravel or bits of brick, for drainage. Plug the hole in the inside pot. Fill the spaces between, c, with earth, and in this set the cuttings. Water may be poured into the inner pot, b, to supply the moisture. [Illustration: Fig. 127. To check evaporation at transplanting.] In the transplanting of cabbages, tomatoes, flowers, and all plants recently started from seeds, it is important that the ground be thoroughly fined and compacted. Plants usually live better if transplanted into ground that has been freshly turned. If possible, transplant in cloudy or rainy weather, particularly if late in the season. Firm the earth snugly about the roots with the hands or feet, in order to bring up the soil moisture; but it is generally best to rake the surface in order to reËstablish the earth-mulch, unless the plants are so small that their roots cannot reach through the mulch (p. 98). If the plants are taken from pots, water the pots some time in advance, and the ball of earth will fall out when the pot is inverted and tapped lightly. In taking up plants from the ground, it is advisable, also, to water them well some time before removing; the earth may then be held on the roots. See that the watering is done far enough in advance to allow the water to settle away and distribute itself; the earth should not be muddy when the plants are removed. [Illustration: Fig. 128. Plants sheared and not sheared when transplanted.] In order to reduce the evaporation from the plant, shingles may be stuck into the ground to shade the plant; or a screen may be improvised with pieces of paper (Fig. 122), tin cans, inverted flower-pots, coverings of brush, or other means. [Illustration: Fig. 129. Where to shear the tops of young plants.] It is nearly always advisable to remove some of the foliage, [Illustration: Fig. 130. Trowel dibber.] [Illustration: Fig. 131. The dibber.] [Illustration: Fig. 132. Home-made padded dibber.] [Illustration: Fig. 133. Dibber and crow-bar combined.] In the transplanting of young plants, some kind of a dibber should be used to make the holes. Dibbers make holes without removing any of the earth. A good form of dibber is shown in Fig. 130, which is like a flat or plane trowel. Many persons prefer a cylindrical and conical dibber, like that shown in Fig. 131. For hard soils and larger plants, a strong dibber may be made from a limb that has a right-angled branch to serve as a handle. This handle may be softened by slipping a piece of rubber hose on it (Fig. 132). A long iron dibber, which may also be used as a crow-bar, is shown in Fig. 133. In transplanting with the dibber, a hole is first made by a thrust of the tool, and the earth [Illustration: Fig. 134. Strawberry planter.] For large plants, a broader dibber may be used. An implement like that shown in Fig. 134 is useful for setting strawberries and other plants with large roots. It is made of two-inch plank, with a block on top to act as foot-rest and to prevent the blade from going too deep. In order to provide space for the foot and easily to direct the thrust, the handle may be placed at one side of the middle. For plunging pots, a dibber like that shown in Fig. 135 is useful, particularly when the soil is so hard that a long-pointed tool is necessary. The bottom of the hole may be filled with earth before the pot is inserted; but it is often advisable to leave the vacant space below (as in b) to provide drainage, to keep the plant from rooting, and to prevent earth-worms from entering the hole in the bottom of the pot. For smaller pots, the tool may be inserted a less depth (as at c). [Illustration: Fig. 135. The plunging of pots.] [Illustration: Fig. 136. Setting large tub-plants in the lawn.] In setting potted plants out of doors, it is nearly always advisable to plunge them,—that is to set the pots into the earth,—unless the place is very wet. The pots are then watered by the rainfall, and demand little care. If the plants are to be [Illustration: Fig. 137. Plant-box with a movable side.] For the shifting of very large tub-plants, a box or tub with movable sides, as in Fig. 137, is handy and efficient. The plant-box recommended to parties who grew plants for exhibition at the World’s Fair is shown in Fig. 138. It is made of strong boards or planks. At A is shown the inside of one of two opposite sections or sides, four feet wide at top, three feet wide at bottom, and three feet high. The cleats are two-by-four scantlings, through which holes are bored to admit the bolts with which the box is to be held together. B is an outside view of one of the alternating sections, three feet four inches wide at top, two feet four inches at bottom, and three feet deep. A one-by-six strip is nailed through the center to give strength. C is an end view of A, showing the bolts and also a two-by-four cleat to which the bottom is to be nailed. This box was used mostly for [Illustration: Fig. 138. Box for transporting large transplanted stock.] In general, it is best to set hardy plants in the fall, particularly if the ground is fairly dry and the exposure is not too bleak. To this class belong most of the fruit trees and ornamental trees and shrubs; also hardy herbs, as columbines, peonies, lilies, bleeding-hearts, and the like. They should be planted as soon as they are thoroughly mature, so that the leaves begin to fall naturally. If any leaves remain on the tree or bush at planting time, strip them off, unless the plant is an evergreen. It is generally best not to cut back fall-planted trees to the full extent desired, but to shorten them three-fourths of the required amount in the fall, and take off the remaining fourth in All tender and very small plants should be set in the spring, in which case very early planting is desirable; and spring planting is always to be advised when the ground is not thoroughly drained and well prepared. In well-compacted land, trees and shrubs should be set at about the same depth as they stood in the nursery, but if the land has been deeply trenched or if it is loose from other causes, the plants should be set deeper, because the earth will probably settle. The hole should be filled with fine surface earth. It is generally not advisable to place manure in the hole, but if it is used, it should be of small amount and very thoroughly mixed with the earth, else it will cause the soil to dry out. In lawns and other places where surface tillage cannot be given, a light mulch of litter or manure may be placed about the plants; but the earth-mulch (page 98), when it can be secured, is much the best conserver of moisture. [Illustration: Fig. 139. A planting board.] In order to set trees in rows, it is necessary to use a garden line (Fig. 96), or to mark out the ground with some of the [Illustration: Fig. 140. Device for placing the tree.] There are various devices for locating the place of the stake after the stake has been removed and the hole dug, in case the area is not regularly staked out in such a way that sighting across the area may be employed. One of the simplest is shown in Fig. 139. It is a narrow and thin board with a notch in the center and a peg in either end, one of the pegs being stationary. The implement is so placed that the notch meets the stake, then one end of it is thrown out of the way until the hole is dug. When the implement is brought again to its original position, the notch mark’s the place of the stake and the tree. Figure 140 is a device with a lid, in the end of which is a notch to mark the place of the stake. This lid is thrown back, as shown by the dotted lines, when the hole is being dug. Figure 141 shows a method of bringing trees in row by measuring from a line. [Illustration: Fig. 141. Lining a tree from a stake.] In the planting of any tree or bush, the roots should be cut back beyond all breaks and serious bruises, and fine earth should be thoroughly filled in and firmed about them, as in Fig. 142. No implement is so good as the fingers for working the soil about the roots. If the tree has many roots, work it up and down slightly several times during the filling of the hole, to settle the earth in place. When the earth is thrown in carelessly, the roots are jammed together, and often an empty place is left beneath the crown, as in Fig. 143, which causes the roots to dry out. [Illustration: Fig. 142: Proper planting of a tree.] [Illustration: Fig. 143: Careless planting of a tree.] [Illustration: Fig. 144. Pruned young tree.] [Illustration: Fig. 145. Pruned young tree.] The marks on the tops of these trees in Figs. 142 and 143 show where the branches may be cut. See also Fig. 152. Figures 144 Always leave a little of the small bud-making growth. The practice of cutting back shade trees to mere long clubs, or poles, with no small twigs, is to be discouraged. The tree in such case is obliged to force out adventitious buds from the old wood, and it may not have vigor enough to do this; and the process may be so long delayed as to allow the tree to be overtaken by drought before it gets a start. [Illustration: Fig. 146: Peach tree.] [Illustration: Fig. 147: Peach tree pruned for planting.] Very large trees can often be moved with safety. It is essential that the transplanting be done when the trees are perfectly dormant,—winter being preferable,—that a large mass of earth and roots be taken with the tree, and that the top be vigorously cut back. Large trees are often moved in winter on a stone-boat, by securing a large ball of earth frozen about [Illustration: Fig. 148: Moving a large tree.] The following more explicit directions for moving large trees are by Edward Hicks, who has had much experience in the business, and who made this report to the press a few years ago: “In moving large trees, say those ten to twelve inches in diameter and twenty-five to thirty feet high, it is well to prepare them by trimming and cutting or sawing off the roots at a proper distance from the trunks, say six to eight feet, in June. The cut roots heal over and send out fibrous roots, which should not be injured more than is necessary in moving the trees next fall or spring. Young, thrifty maples and elms, originally from the nursery, do not need such preparation nearly as much as other and older trees. In moving a tree, we begin by digging a wide trench six to eight feet from it, leaving all possible roots fast to it. By digging under the tree in the wide trench, and working the soil out of the roots by means of round or dull-pointed sticks, the soil falls into the cavity made under the tree. Three or four men in as many hours could get so much of the soil away from the roots that it would be safe to attach a rope and tackle to the upper part of the trunk and to some adjoining post or tree for the purpose of pulling the tree over. A good quantity of bagging must be put around the tree under the rope to prevent injury, and care should be taken that the pulling of the rope does not split off or break a limb. A team is hitched to [Illustration: Fig. 149. The tree ready to lift.] [Illustration: 150. The tree ready to move.] [Illustration: Fig. 151. Trees heeled-in for winter.] If the ground is not ready for planting in the fall, or if it is desired for any reason to delay until spring, the trees or bushes may be heeled-in, as illustrated in Fig. 151. The roots are laid in a furrow or trench, and are covered with well-firmed earth. Straw or manure may be thrown over the earth still further to protect the roots, but if it is thrown over the tops, mice may be attracted by it and the trees be girdled. Tender trees or bushes may be lightly covered to the tips with earth. Plants should be heeled-in only in loose, warm, loamy or sandy ground and in a well-drained place. [Illustration: Fig. 152. Tree earthed up for winter.] It is always advisable to mulch plants that are set in the fall. Any loose and dry material—as straw, manure, leaves, leafmold, litter from yards and stables, pine boughs—may be used for this purpose. Very strong or compact manures, as those in which there is little straw or litter, should be avoided. The ground may be covered to a depth of five or six inches, or even a foot or more if the material is loose. Avoid throwing strong manure directly on the crown of the plants, especially of herbs, for the materials that leach from the manure sometimes injure the crown buds and the roots. This protection may also be given to established plants, particularly to those which, like roses and herbaceous plants, are expected to give a profusion of bloom the following year. This mulch affords not only winter protection, but is an efficient means of fertilizing the land. A large part of the plant-food materials have leached out of the mulch by spring, and have become incorporated in the soil, where the plant makes ready use of them. [Illustration: Fig. 153: Covering plants in a box.] Mulches also serve a most useful purpose in preventing the ground from packing and baking by the weight of snows and rains, and the cementing action of too much water in the surface [Illustration: Fig. 154: Covering plants in a barrel.] Tender bushes and small trees may be wrapped with straw, hay, burlaps, or pieces of matting or carpet. Even rather large trees, as bearing peach trees, are often baled up in this way, or sometimes with corn fodder, although the results in the protection of fruit-buds are not often very satisfactory. It is important that no grain is left in the baling material, else mice may be attracted to it. (The danger of gnawing by mice that nest in winter coverings is always to be anticipated.) It should be known, too, that the object in tying up or baling plants is not so much to protect from direct cold as to mitigate the effects of alternate freezing and thawing, and to protect from drying winds. Plants may be wrapped so thick and tight as to injure them. The labor of protecting large plants is often great and the results uncertain, and in most cases it is a question whether more satisfaction could not be attained by growing only hardy trees and shrubs. The objection to covering tender woody plants cannot be urged with equal force against tender herbs or very low bushes, for these are protected with ease. Even the ordinary mulch may afford sufficient protection; and if the tops kill back, the plant quickly renews itself from near the base, and in many plants—as in most hybrid perpetual roses—the best bloom is Connoisseurs of tender roses and other plants sometimes go to the pains of erecting a collapsible shed over the bush, and filling with leaves or straw. Whether this is worth while depends wholly on the degree of satisfaction that one derives from the growing of choice plants (see Roses, in Chap. VIII). [Illustration: Fig. 155. Laying down of trellis-grown blackberries.] The tops of plants may be laid down for the winter. Figure 155 shows a method of laying down blackberries, as practiced in the Hudson River valley. The plants were tied to a trellis, as the method is in that country, two wires (a, b) having been run on either side of the row. The posts are hinged on a pivot to a short post (c), and are held in position by a brace (d). The entire trellis is then laid down on the approach of winter, as shown in the illustration. The blackberry tops are so strong that they hold the wires up from the ground, even when the trellis is laid In severe climates, or in the case of tender plants, the tops should be covered with straw, boughs, or litter, as recommended for regular mulch-covers. Sometimes a V-shaped trough made from two boards is placed over the stems of long or vine-like plants that have been laid down. All plants with slender or more or less pliant stems can be laid down with ease. With such protection, figs can be grown in the northern states. Peach and other fruit trees may be so trained as to be tipped over and covered. Laid-down plants are often injured if the covering remains too late in the spring. The ground warms up early, and may start the buds on parts of the buried plants, and these tender buds may be broken when the plants are raised, or injured by sun, wind, or frost. The plants should be raised while the wood and buds are still hard and dormant. Pruning is necessary to keep plants in shape, to make them more floriferous and fruitful, and to hold them within bounds. Even annual plants often may be pruned to advantage. This is true of tomatoes, from which the superfluous or crowding shoots may be removed, especially if the land is so rich that they grow very luxuriantly; sometimes they are trained to a single stem and most of the side shoots are taken away as they appear. If plants of marigold, gaillardia, or other strong and spreading growers are held by stakes or wire-holders (a good practice), it may be advisable to remove the weak and sprawling shoots. Balsams give better results when side shoots are Distinction should be made between pruning and shearing. Plants are sheared into given shapes. This may be necessary in bedding-plants, and occasionally when a formal effect is desired in shrubs and trees; but the best taste is displayed, in the vast majority of cases, in allowing the plants to assume their natural habits, merely keeping them shapely, cutting out old or dead wood, and, in some cases, preventing such crowding of shoots as will reduce the size of the bloom. The common practice of shearing shrubbery is very much to be reprehended; this subject is discussed from another point of view on page 24. The pruner should know the flower-bearing habit of the plant that he prunes,—whether the bloom is on the shoots of last season or on the new wood of the present season, and whether the flower-buds of spring-blooming plants are separate from the leaf-buds. A very little careful observation will determine these points for any plant. (1) The spring-blooming woody plants usually produce their flowers from buds perfected the fall before and remaining dormant over winter. This is true of most fruit-trees, and such shrubs as lilac, forsythia, tree peony, wistaria, some spireas and viburnums, weigela, deutzia. Cutting back the shoots of these plants early in spring or late in fall, therefore, removes the bloom. The proper time to prune such plants (unless one intends to reduce or thin the bloom) is just after the flowering season. (2) The summer-blooming woody plants usually produce their flowers on shoots that grow early in the same season. This is true of grapes, quince, hybrid perpetual roses, shrubby hibiscus, crape myrtle, mock orange, hydrangea (paniculata), and others. Pruning in winter or early spring to secure strong new shoots is, therefore, the proper procedure in these cases. Remarks on pruning may be found under the discussion of Fruit-trees and shade-trees are usually pruned in winter, preferably late in winter, or in very early spring. However, there is usually no objection to moderate pruning at any time of the year; and moderate pruning every year, rather than violent pruning in occasional years, is to be advised. It is an old idea that summer pruning tends to favor the production of fruit-buds and therefore to make for fruitfulness; there is undoubtedly truth in this, but it must be remembered that fruitfulness is not the result of one treatment or condition, but of all the conditions under which the plant lives. All limbs should be removed close to the branch or trunk from which they arise, and the surface of the wound should be practically parallel with such branch or trunk, rather than to be cut back to stubs. The stubs do not heal readily. All wounds much above an inch across may be protected by a coat of good linseed-oil paint; but smaller wounds, if the tree is vigorous, usually require no protection. The object of the paint is to protect the wound from cracking and decay until the healing tissue covers it. Superfluous and interfering branches should be removed from fruit-trees, so that the top will be fairly open to sun and to the pickers. Well-pruned trees allow of an even distribution and uniform development of the fruit. Watersprouts and suckers should be removed as soon as they are discovered. How open the top may be, will depend on the climate. In the West, open trees suffer from sun-scald. The fruit-bearing habit of the fruit-tree must be considered in the pruning. The pruner should be able to distinguish fruit-buds from leaf-buds in such species as cherries, plums, apricot, peach, pear, apple, and so prune as to spare these buds or to thin them understandingly. The fruit-buds are distinguished by their position on the tree and by their size and shape. They Aside from the regular pruning to develop the tree into its best form to enable it to do its best work, there are wounds and malformations to be treated. Recently, the treating of injured and decayed trees has received much attention, and “tree doctors” and “tree surgeons” have engaged in the business. If there are quacks among these people, there are also competent and reliable men who are doing useful service in saving and prolonging the life of trees; one should choose a tree doctor with the same care that he would choose any other doctor. The liability of injury to street trees in the modern city and the increasing regard for trees, render the services of good experts increasingly necessary. Street trees are injured by many causes: as, starving because of poor soil and lack of water under pavements; smoke and dust; leakage from gas mains and from electric installation; gnawing by horses; butchering by persons stringing wires; carelessness of contractors and builders; wind and ice storms; overcrowding; and the blundering work of persons who think that they know how to prune. Well-enforced municipal regulations should be able to control most of these troubles. [Illustration: Fig. 156. Lath tree guard.] [Illustration: Fig. 157. Wire-and-post tree guard] Along roadsides and other exposed places it is often necessary to protect newly set trees from horses, boys, and vehicles. There are various kinds of tree guards for this purpose. The best types are those that are more or less open, so as to allow the free passage of air and which are so far removed from the body of the tree that its trunk may expand without difficulty. If the guards are very tight, they may shade the trunk so much that the tree may suffer when the guard is removed, and they prevent the discovery of insects and injuries. It is important that the guard does not fill with litter in which insects may harbor. As soon as the tree is old enough to escape injury, the guards should be removed. A very good guard, made of laths held together with three strips of band-iron, and secured to iron posts, is shown in Fig. 156. Figure 157. shows a guard made by winding fencing wire upon three posts or stakes. When there is likely to be danger from too great shading of the trunk, this latter form of [Illustration: Fig 158. How a horse may be hitched to a tree.] Trees and bushes are often seriously injured by the gnawing of mice and rabbits. The best preventive is not to have the vermin. If there are no places in which rabbits and mice can burrow and breed, there will be little difficulty. At the approach of winter, if mice are feared, the dry litter should be removed from about the trees, or it should be packed down very firm, so that the mice cannot nest in it. If the rodents are very abundant, it may be advisable to wrap fine wire netting about the base of the tree. A boy who is fond of trapping or hunting will ordinarily solve the rabbit difficulty. Rags tied on sticks which are placed at intervals about the plantation will often frighten rabbits away. [Illustration: Fig. 159. Bridge-grafting a girdle.] Trees that are girdled by mice should be wrapped up as soon as discovered, so that the wood shall not become too dry. When In some cases, however, it is necessary to join the bark above and below the girdle by means of cions, which are whittled to a wedge-shape on either end, and inserted underneath the two edges of the bark (Fig. 159). The ends of the cions and the edges of the wound are held by a bandage of cloth, and the whole work is protected by melted grafting-wax poured upon it. [Footnote: A good grafting-wax is made as follows: Into a kettle place one part by weight of tallow, two parts of beeswax, four parts of rosin. When completely melted, pour into a tub or pail of cold water, then work it with the hands (which should be greased) until it develops a grain and becomes the color of taffy candy. The whole question of the propagation of plants is discussed in “The Nursery-Book.”] [Illustration: Fig. 161. A wound, made by freezing, trimmed out and filled with cement.] The following advice on “tree surgery” is by A.D. Taylor (Bulletin 256, Cornell University, from which the accompanying illustrations are adapted):— [Illustration: Fig. 160. A cement-filled cavity at the base of a tree.] “Successful operation depends on two important factors: first, that all decayed parts of the cavity be wholly removed and the exposed surface thoroughly washed with an antiseptic; second, that the cavity, when filled, must be air tight and hermetically sealed if possible. Trees are treated as follows: The cavity is thoroughly cleaned by removing all decayed wood and washing the interior surface with a solution of copper sulfate and lime, in order to destroy any fungi that may remain. The edges of the cavity are cut smooth in order to allow free growth of the cambium after the cavity is filled. Any antiseptic, such as corrosive sublimate, creosote, or even paint, may answer the purpose; creosote, however, possesses the most penetrating powers of any. The method of filling the cavities depends to a great extent on their size and form. Very large cavities with great openings are generally bricked on the outside, over the “Fillings thus made are considered by expert tree surgeons to be a permanent preventive of decay. The outside of the filling is always coated with a thin covering of concrete, consisting of one part cement to two parts fine sand. Cavities resulting from freezing, and which, though large on the inside, show only a long narrow crack on the outside, are most easily filled by placing a form against the entire length of the opening, having a space at the top through which the cement may be poured (Fig. 161). Another method of retaining the concrete is to reinforce it from the outside by driving rows of spikes along the inner surface of either side of the cavity and lacing a stout wire across the face of the cavity. For best results, all fillings must come flush with the inner bark when finished. During the first year, this growing tissue will spread over the outer edge of the filling, thus forming an hermetically sealed cavity. In the course of time, the outside of small or narrow openings should be completely covered with tissue, which buries the filling from view. [Illustration: Fig. 162. Bridge-grafting or in-arching from saplings planted about the tree.] [Illustration: Fig. 163. Faulty methods of bracing a crotched tree. The lower method is wholly wrong. The upper method is good if the bolt-heads are properly counter-sunk and the bolts tightly fitted; but if the distance between the branches is great, it is better to have two bolts and join them by hooks, to allow of wind movements.] “In addition to the preservation of decayed specimens by filling the cavities, as above outlined, it has been proposed to strengthen the tree by treating it as shown in Fig. 162. Young saplings of the same species, after having become established as shown, are grafted by approach to the mature specimen. “Injury frequently results from error in the method of attempting to save broken, or to strengthen and support weak branches that are otherwise healthy. The means used for supporting cracked, wind-racked, and overladen branches which show a tendency to split at the forks are bolting and chaining. The practice of placing iron bands around large branches in order to protect them has resulted in much harm; as the tree grows and expands, such bands tighten, causing the bark to be broken and resulting after a few years in a partial girdling (Fig. 163). [Illustration: Fig. 164. Trees ruined to allow of the passage of wires.] [Illustration: Fig. 165. Accommodating a wall to a valuable tree.] [Illustration: Fig. 166. The death of a long stub.] [Illustration: Fig. 167. Bungling pruning.] [Illustration: Fig. 168. The proper way to saw off a large limb. A cut is first made on the under side to prevent splitting down; then it is cut on the upper side. Then the entire “stub” is removed close to the trunk.] [Illustration: Fig. 169.

An allowable way of attaching a guy rope.] [Illustration: Fig. 172. The best way of attaching a guy rope, if a tree must be used as support.] “The inner ends of the rods in the two branches may be connected by a rod or chain. The preference for the chain over the rod attachment is based on the compressive and tensile stresses which come on the connection during wind storms. Rod connections are preferred, however, when rigidity is required, as in unions made close to the crotch; but for tying two branches together before they have shown signs of weakening at the fork, the chain may best be used, as the point of attachment may be placed some distance from the crotch, where the flexibility factor will be important and the strain comparatively small. Elms in an advanced stage of maturity, if subjected to severe climatic conditions, often show this tendency to split. These [Illustration: Fig. 173. A method of saving valuable trees along streets on which heavy lowering of grade has been made.] The illustrations, Figs. 164-173, are self-explanatory, and show poor practice and good practice in the care of trees. Grafting is the operation of inserting a piece of a plant into another plant with the intention that it shall grow. It differs from the making of cuttings in the fact that the severed part grows in another plant rather than in the soil. There are two general kinds of grafting—one of which inserts a piece of branch in the stock (grafting proper), and one which inserts only a bud with little or no wood attached (budding). In both cases the success of the operation depends on the growing together of the cambium of the cion (or cutting) and that of the stock. The cambium is the new and growing tissue lying underneath the bark and on the outside of the growing wood. Therefore, the line of demarcation between the bark and the wood should coincide when the cion and stock are joined. The plant on which the severed piece is set is called the stock. The part which is removed and set into the stock is called a cion if it is a piece of a branch, or a “bud” if it is only a single bud with a bit of tissue attached. The greater part of grafting and budding is performed when the cion or bud is nearly or quite dormant. That is, grafting is usually done late in winter and early in spring, and budding [Illustration: Fig. 174. Budding. The “bud”; the opening to receive it; the bud tied.] The chief object of grafting is to perpetuate a kind of plant which will not reproduce itself from seed, or of which seed is very difficult to obtain. Cions or buds are therefore taken from this plant and set into whatever kind of plant is obtainable on which they will grow. Thus, if one wants to propagate the Baldwin apple, he does not for that purpose sow seeds thereof, but takes cions or buds from a Baldwin tree and grafts them into some other apple tree. The stocks are usually obtained from seeds. In the case of the apple, young plants are raised from seeds which are secured mostly from cider factories, without reference to the variety from which they came. When the seedlings have grown to a certain age, they are budded or grafted, the grafted part making the entire top of the tree; and the top bears fruit like that of the tree from which the cions were taken. There are many ways in which the union between cion and stock is made. Budding may be first discussed. It consists in inserting a bud underneath the bark of the stock, and the commonest practice is that which is shown in the illustrations. Budding is mostly performed in July, August, and early September, when the bark is still loose or in condition to peel. Twigs are cut from the tree which it is desired to propagate, and the buds are cut off with a sharp knife, a shield-shaped bit of bark (with possibly a little wood) being left with them (Fig. 174). The bud is then shoved into a slit made in the [Illustration: Fig. 175. Whip-graft.] Grafting is the insertion of a small branch (or cion), usually bearing more than one bud. If grafting is employed on small stocks, it is customary to employ the whip-graft (Fig. 175). Both stock and cion are cut across diagonally, and a split made in each, so that one fits into the other. The graft is tied securely with a string, and then, if it is above ground, it is also waxed carefully. [Illustration: Fig. 176. Cleft-graft before waxing.] In larger limbs or stocks, the common method is to employ Grafting is usually performed early in the spring, just before the buds swell. The cions should have been cut before this time, when they were perfectly dormant. Cions may be stored in sand in the cellar or in the ice-house, or they may be buried in the field. The object is to keep them fresh and dormant until they are wanted. If it is desired to change the top of an old plum, apple, or pear tree to some other variety, it is usually accomplished by means of the cleft-graft. If the tree is very young, budding or whip-grafting may be employed. On an old top the cions should begin to bear when three to four years old. All the main limbs should be grafted. It is important to keep down the suckers or watersprouts from around the grafts, and part of the remaining top should be cut away each year until the top is entirely changed over (which will result in two to four years). A good wax for covering the exposed parts is described in the footnote on page 145. If one has a large and valuable collection of fruit or ornamental plants, it is desirable that he have some permanent record of them. The most satisfactory method is to label the plants, and then to make a chart or map on which the various plants are indicated in their proper positions. The labels are always liable to be lost and to become illegible, and they are often misplaced by careless workmen or mischievous boys. [Illustration: Fig. 177. The common stake label.] [Illustration: Fig. 178. A good stake label, with the legend covered.] For more permanent herbaceous plants, as rhubarb and asparagus, or even for bushes, a stake that is sawed from clear pine or cypress, eighteen inches long, three inches wide, and an inch or more thick, affords a most excellent label. The lower end of the stake is sawed to a point, and is dipped in coal tar or creosote, or other preservative. The top of the stake is painted white, and the legend is written with a large and soft pencil. When the writing becomes illegible or the stake is needed for other plants, a shaving is taken off the face of the label with a plane, a fresh coat of paint added, and the label is as good as ever. These labels are strong enough to withstand shocks from whiffletrees and tools, and should last ten years. Whenever a legend is written with a lead pencil, it is advisable to use the pencil when the paint (which should be white lead) is still fresh or soft. Figure 178 shows a very good device for preserving the writing on the face of the label. A block of wood is secured to the label by means of a screw, covering the legend completely and protecting it from the weather. If more ornamental stake labels are desired, various types can be bought in the market, or one can be made after the fashion of Fig. 179. This is a zinc plate that can be painted black, on [Illustration: Fig. 179. Metal stake label.] [Illustration: Fig. 180. Zinc tallies.] [Illustration: Fig. 181. Common zinc tally.] For labeling trees, various kinds of zinc tallies are in common use, as shown in Figs. 180 and 181. Fresh zinc takes a lead pencil readily, and the writing often becomes more legible as it becomes older, and it will usually remain three or four years. These labels are attached either by wires, as a, b, Fig. 180, or they are wound about the limb as shown in c, d, and e, in Fig. 180. The type of zinc label most in use is a simple strip of zinc, as shown in Fig. 181, wrapped about the limb. The metal is so flexible that it expands readily with the growth of the branch. While these zinc labels are durable, they are very inconspicuous because of their neutral color, and it is often difficult to find them in dense masses of foliage. The common wooden label of the nurserymen (Fig. 182) is perhaps as useful as any for general purposes. If the label has had a light coat of thin white lead, and the legend has been made [Illustration: Fig. 182. A common nursery label.] [Illustration: Fig. 183. Cornell tree label.] [Illustration: Fig. 184. Serviceable large-loop tree label.] [Illustration: Fig. 185. Zinc tree label.] [Illustration: Fig. 186. Injury by a tight label wire.] [Illustration: Fig. 187. The old-fashioned “outdoor cellar,” still a very useful and convenient storage place.] The principles involved in the storing of perishable products, as fruits and vegetables, differ with the different commodities. All the root-crops, and most fruits, need to be kept in a cool, moist, and uniform temperature if they are to be preserved a great length of time. Squashes, sweet-potatoes, and some other things need to be kept in an intermediate and what might be called a high temperature; and the atmosphere should be drier than for most other products. The low temperature has the effect of arresting decomposition and the work of fungi and bacteria. The moist atmosphere has the effect of preventing too great evaporation and the consequent shriveling. In the storing of any commodity, it is very important that the product is in proper condition for keeping. Discard all specimens that are bruised or are likely to decay. Much of the decay of fruits and vegetables in storage is not the fault of [Illustration: Fig. 188. Lean-to fruit cellar, covered with earth. The roof should be of cement or stone slabs. Provide a ventilator.] Apples, winter pears, and all roots, should be kept at a temperature somewhat near the freezing point. It should not rise above 40° F. for best results. Apples can be kept even at one or two degrees below the freezing point if the temperature is uniform. Cellars in which there are heaters are likely to be too dry and the temperature too high. In such places it is well to keep fresh vegetables and fruits in tight receptacles, and pack the roots in sand or moss in order to prevent shriveling. In these places, apples usually keep better if headed up in barrels than if kept on racks or shelves. In moist and cool cellars, however, it is preferable for the home supply to place them on shelves, not piling them more than five or six inches deep, for then they can be sorted over as occasion requires. In case of fruits, be sure that the specimens are not over-ripe when placed in storage. If apples are allowed to lie in the sun for a few days before being packed, they will ripen so much that it is very difficult to keep them. Cabbages should be kept at a low and uniform temperature, and water should be drained away from them. They are stored in many ways in the field, but success depends so much on the season, particular variety, ripeness, and the freedom from injuries by fungi and insects, that uniform results are rarely secured by any one method. The best results are to be [Illustration: Fig. 189. A fruit storage house cooled by ice.] When vegetables are wanted at intervals during the winter from pits, it is well to make compartment pits, each compartment holding a wagon load or whatever quantity will be likely to be wanted at each time. These pits are sunk in well-drained land, and between each of the two pits is left a wall of earth about a foot thick. One pit can then be emptied in cold weather without interfering with the others. An outside cellar is better than a house cellar in which there is a heater, but it is not so handy. If it is near the house, it need not be inconvenient, however. A house is usually healthier if the cellar is not used for storage. House cellars used for storage should have a ventilating shaft. Some of the principles involved in an ice-cooled storage house are explained in the diagram, Fig. 189. If the reader desires to make a careful study of storage and storage structures, he should consult cyclopedias and special articles. There are three general means (aside from greenhouses) of forcing plants ahead of their season in the early spring—by means of forcing-hills and hand-boxes, by coldframes, and by hotbeds. The forcing-hill is an arrangement by means of which a single plant or a single “hill” of plants may be forced where it [Illustration: Fig. 190. Forcing-hill for rhubarb.] In Fig. 190 is illustrated a common method of hastening the growth of rhubarb in the spring. A box with four removable sides, two of which are shown in end section in the figure, is placed around the plant in the fall. The inside of the box is filled with straw or litter, and the outside is banked thoroughly with any refuse, to prevent the ground from freezing. When it is desired to start the plants, the covering is removed from both the inside and outside of the box and hot manure is piled around the box to its top. If the weather is yet cold, dry light leaves or straw may be placed inside the box; or a pane or sash of glass may be placed on top of the box, when it will become a coldframe. Rhubarb, asparagus, sea-kale, and similar plants may be advanced two or four weeks by means of this method of forcing. Some gardeners use old barrels or half-barrels in place of the box. The box, however, is better and handier, and the sides can be stored for future use. [Illustration: Fig. 191. Forcing-hill, and the mold or frame for making it.] Plants that require a long season in which to mature, and which do not transplant readily, as melons and cucumbers, may be planted in forcing-hills in the field. One of these hills is shown in Fig. 191. The frame or mold is shown at the left. This mold is a box with flaring sides and no top or bottom, and [Illustration: Fig. 192. Hand-box.] A forcing-hill is sometimes made by digging a hole in the ground and planting the seeds in the bottom of it, placing the pane of glass upon a slight ridge or mound which is made on the surface of the ground. This method is less desirable than the other, because the seeds are placed in the poorest and coldest soil, and the hole is very likely to fill with water in the early days of spring. An excellent type of forcing-hill is made by the use of the hand-box, as shown in Fig. 192. This is a rectangular box, without top or bottom, and a pane of glass is slipped into a groove at the top. It is really a miniature coldframe. The earth is banked up slightly about the box, in order to hold it against winds and to prevent the water from running into it. If these boxes are made of good lumber and painted, they will last for many years. Any size of glass may be used which is desired, but a ten-by-twelve pane is as good as any for general purposes. After the plants are thoroughly established in these forcing-hills, and the weather is settled, the protection is wholly removed, and the plants grow normally in the open. [Illustration: Fig. 193. Glass forcing-hill.] In all forcing-hills, as in coldframes and hotbeds, it is exceedingly important that the plants receive plenty of air on bright days. Plants that are kept too close become weak or “drawn”, and lose the ability to withstand changes of weather when the protection is removed. Even though the wind is cold and raw, the plants inside the frames ordinarily will not suffer if the glass is taken off when the sun is shining. A coldframe is nothing more than an enlarged hand-box; that is, instead of protecting but a single plant or a single hill with a single pane of glass, the frame is covered with sash, and is large enough to accommodate many plants. There are three general purposes for which a coldframe is used: For the starting of plants early in spring; for receiving partially hardened plants that have been started earlier in hotbeds and forcing-houses; for wintering young cabbages, lettuce, and other hardy plants that are sown in the fall. [Illustration: Fig. 194. Coldframe against a building. Plants at E; sill of house at A; basement opening at B.] Coldframes are ordinarily placed near the buildings, and the plants are transplanted into the field when settled weather comes. Sometimes, however, they are made directly in the field where the plants are to remain, and the frames, and not the plants, are removed. When used for this latter purpose, the frames are made very cheap by running two rows of parallel [Illustration: Fig. 195. Weather screen, or coldframe, against a building.] One of the simplest types of coldframes is shown in Fig. 194, which is a lean-to against the foundation of a house. A sill is run just above the surface of the ground, and the sashes, shown at D, are laid on rafters which run from this sill to the sill of the house, A. If this frame is on the south side of the building, plants may be started even as early as a month before the opening of the season. Such lean-to frames are sometimes made against greenhouses or warm cellars, and heat is supplied to them by the opening of a door in the wall, as at B. In frames that are in such sunny positions as these, it is exceedingly important that care be taken to remove the sash, or at least to give ample ventilation, in all sunny days. A different type of lean-to structure is shown in Fig. 195. This may be either a temporary or permanent building, and [Illustration: Fig. 196. A pit or coldframe on permanent walls, and a useful adjunct to a garden. The rear cover is open (_a_).] [Illustration: Fig. 197. The usual form of coldframe.] [Illustration: Fig. 198. A strong and durable frame.] Another structure that may be used both to carry half-hardy plants over winter and for starting plants early in spring is shown in Fig. 196. It is really a miniature greenhouse without heat. It is well adapted for mild climates. The The common type of coldframe is shown in Fig. 197. It is twelve feet long and six feet wide, and is covered with four three-by-six sash. It is made of ordinary lumber loosely nailed together. If one expects to use coldframes or hotbeds every year, however, it is advisable to make the frames of two-inch stuff, well painted, and to join the parts by bolts and tenons, so that they may be taken apart and stored until needed for the next year’s crop. Figure 198 suggests a method of making frames so that they may be taken apart. [Illustration: Fig. 199. A frame yard.] [Illustration: Fig. 200. Portable coldframe.] [Illustration: Fig. 201. A larger portable coldframe.] [Illustration: Fig. 202. A commodious portable frame.] It is always advisable to place coldframes and hotbeds in a protected place, and particularly to protect them from cold north winds. Buildings afford excellent protection, but the sun is [Illustration: Fig. 203. A low coldframe.] Various small and portable coldframes may be used about the garden for the protection of tender plants or to start them early in the spring. Pansies, daisies, and border carnations, for example, may be brought on very early by setting such frames over them or by planting them under the frames in the fall. These frames may be of any size desired, and the sash may be either removable, or, in case of small frames, they may be hinged at the top. Figs. 200-203 illustrate various types. A hotbed differs from a coldframe in being provided with bottom heat. This heat is ordinarily supplied by means of fermenting manure, but it may be obtained from other fermenting material, as tanbark or leaves, or from artificial heat, as flues, steam pipes, or water pipes. The date at which the hotbed may be started with safety depends almost entirely on the means at command of heating it and on the skill of the operator. In the northern states, where outdoor gardening does not begin until the first or the last of May, hotbeds are sometimes started as early as January; but they are ordinarily delayed until early in March. The heat for hotbeds is commonly supplied by the fermentation of horse manure. It is important that the manure be as uniform as possible in composition and texture, that it come from highly fed horses, and is practically of the same age. The best results are usually secured with manure from livery stables, from which it can be obtained in large quantities in a short space of time. Perhaps as much as one half of the whole material should be of litter or straw that has been used in the bedding. [Illustration: Fig. 204. Hotbed with manure on top of the ground.] The manure is placed in a long and shallow square-topped pile, not more than four or six feet high, as a rule, and is then allowed to ferment. Better results are generally obtained if the manure is piled under cover. If the weather is cold and fermentation does not start readily, wetting the pile with hot water may start it. The first fermentation is nearly always irregular; that is, it begins unequally in several places in the pile. In order to make the fermentation uniform, the pile must be turned occasionally, taking care to break up all hard lumps and to distribute the hot manure throughout the mass. It is sometimes necessary to turn the pile five or six times before it is finally used, although half this number of turnings is ordinarily sufficient. When the pile is steaming uniformly throughout, it is Hotbed frames are sometimes set on top of the pile of fermenting manure, as shown in Fig. 204. The manure should extend some distance beyond the edges of the frame; otherwise the frame will become too cold about the outside, and the plants will suffer. [Illustration: Fig. 205. Section of a hotbed built with a pit.] It is preferable, however, to have a pit beneath the frame in which the manure is placed. If the bed is to be started in midwinter or very early in the spring, it is advisable to make this pit in the fall and to fill it with straw or other litter to prevent the earth from freezing deep. When it is time to make the bed, the litter is thrown out, and the ground is warm and ready to receive the fermenting manure. The pit should be a foot wider on either side than the width of the frame. Fig. 205 is a cross-section of such a hotbed pit. Upon the ground a layer of an inch or two of any coarse material is placed to keep the manure off the cold earth. Upon this, from twelve to thirty inches of manure is placed. Above the manure is a thin layer of leafmold or some porous material, that will serve as a distributor of the heat, and above this is four or five inches of soft garden loam, in which the plants are to be grown. The manure will ordinarily heat very vigorously for a few days after it is placed in the bed. A soil thermometer should be [Illustration: Fig. 206 Parallel runs of hotbeds with racks for holding sashes.] If hotbeds are to be used every year, permanent pits should be provided for them. Pits are made from two to three feet deep, preferably the former depth, and are walled up with stone or brick. It is important that they be given good drainage from below. In the summer-time, after the sash are stripped, the old beds may be used for the growing of various delicate crops, as melons or half-hardy flowers. In this position, the plants can be protected in the fall. As already suggested, the pits should be cleaned out in the fall and filled with litter to facilitate the work of making the new bed in the winter or spring. [Illustration: Fig. 207. Manure-heated greenhouse.] Various modifications of the common type of hotbed will suggest themselves to the operator. The frames should ordinarily run in parallel rows, so that a man walking between them can attend to the ventilation of two rows of sash at once. Fig. 206 shows a different arrangement. There are two parallel runs, with walks on the outside, and between them are racks to receive the sash from the adjacent frames. The sash from the left-hand bed are run to the right, and those from the right-hand bed are run to the left. Running on racks, the operator does not need to handle them, and the breakage of glass is therefore less; but this system is little used because If the hotbed were high enough and broad enough to allow a man to work inside, we should have a forcing-house. Such a structure is shown in Fig. 207, upon one side of which the manure and soil are already in place. These manure-heated houses are often very efficient, and are a good make-shift until such time as the gardener can afford to put in flue or pipe heat. Hotbeds may be heated by means of steam or hot water. They can be piped from the heater in a dwelling-house or greenhouse. Fig. 208 shows a hotbed with two pipes, in the positions 7, 7 beneath the bed. The earth is shown at 4, and the plants (which, in this case, are vines) are growing upon a rack, at 6. There are doors in the end of the house, shown in 2, 2, which may be used for ventilation or for admitting air underneath the beds. The pipes should not be surrounded by earth, but should run through a free air space. [Illustration: Fig. 208. Pipe-heated hotbed.] It would scarcely pay to put in a hot water or steam heater for the express purpose of heating hotbeds, for if such an expense were incurred, it would be better to make a forcing-house. Hotbeds may be heated, however, with hot-air flues with very good results. A home-made brick furnace may be constructed in a pit at one end of the run and underneath a shed, and the [Illustration: Fig. 209. Useful kinds of watering-pots. These are adapted to different uses, as are different forms of hoes or pruning tools.] The most satisfactory material for use in hotbed and cold-frame sash is double-thick, second-quality glass; and panes Close attention is required in the management of hotbeds, to insure that they do not become too hot when the sun comes out suddenly, and to give plenty of fresh air. Ventilation is usually effected by raising the sash at the upper end and letting it rest upon a block. Whenever the temperature is above freezing point, it is generally advisable to take the sash off part way, as shown in the central part of Fig. 199, or even to strip it off entirely, as shown in Fig. 197. Care should be taken not to water the plants at nightfall, especially in dull and cold weather, but to give them water in the morning, when the sun will soon bring the temperature up to its normal state. Skill and judgment in watering are of the greatest importance in the management of hotbeds; but this skill comes only from thoughtful practice. The satisfaction and effectiveness of the work are greatly increased by good hose connections and good watering-pots (Fig. 209). Some protection, other than the glass, must be given to hotbeds. They need covering on every cold night, and sometimes during the entire day in very severe weather. Very good material for covering the sash is matting, such as is used for [Illustration: Fig. 210. The making of straw mats.] Gardeners often make mats of rye straw, although the price of good straw and the excellence of manufactured materials make this home-made matting less desirable than formerly. Such mats are thick and durable, and are rolled up in the morning, as shown in Fig. 199. There are various methods of making these straw mats, but Fig. 210 illustrates one of the best. A frame is made after the manner of a saw-horse, with a double top, and tarred or marline twine is used for securing the strands of straw. It is customary to use six runs of this warp. Twelve spools of string are provided, six hanging on either side. Some persons wind the cord upon two twenty-penny nails, as shown in the figure, these nails being held together at one end by wire which is secured in notches filed into them. The other ends of the spikes are free, and allow the string to be caught between them, thus preventing the balls from unwinding as they hang upon the frame. Two wisps of straight rye straw are secured and laid upon the frame, with the butt ends outward and the heads overlapping. Two opposite spools are then brought up, and a hard knot is tied at each point. The projecting butts of the straw are then cut off with a hatchet, and the mat is allowed to drop through to receive the next pair of wisps. In making these mats, it is essential that the rye contains no ripe grain; otherwise it attracts the mice. It is best to grow rye for this especial purpose, and to cut it before the grain is in the milk, so that the straw does not need to be threshed. In the growing of plants in hotbeds, every effort should be made to prevent the plants from growing spindling, or becoming “drawn.” To make stocky plants, it is necessary to give room to each plant, to be sure that the distance from the plants to the glass is not great, to provide not too much water in dull and cold weather, and particularly to give abundance of air. |
