PRUNING AND PROPAGATING Of all the many toils and anxieties that beset the path of the amateur rosarian, I think we may safely say pruning is the chief. The rules to be observed are few. The idiosyncrasies of each rose are many. And the demands upon one's own judgment and initiative are constant. Two things have to be considered before we begin the puzzling task. Are we growing our roses for exhibition, or at all events for a very few very perfect blooms? Or are we growing them for quantity, for mere enjoyment, on the "cut and come again" principle, which enables one not only to fill the house without robbing the garden, but to fill the hands of every one who comes into the garden and looks at the masses of blossom with longing eyes? As I do not exhibit, the second plan is the one I have studied most closely. For the other I must refer my readers to my friend the Rev. F. Page-Roberts' valuable notes, on how to grow and show roses in Chapter XI. When to prune.—The old-fashioned plan of Pruning now begins in February, and goes on through March and April. In February we begin to prune the Rugosas; Boursaults; Sempervirens; and Ayrshires. In February and early March, the Provence; Moss; miniature Provence; many of the Species, such as Alpina, Moschata, and Bracteata, and their hybrids. In early March the Gallica; Damask; Alba; Hybrid Chinas; and Sweet Briars. To be followed by Hybrid Bourbons; Hybrid Noisettes and Musks; Austrian and Scotch Briars; Multifloras; Ramblers; Wichuraianas; Chinas; Dijon Teas; dwarf Polyanthas; and dwarf and standard Hybrid Perpetuals and Hybrid Teas. Climbing varieties of Noisettes, Teas, Hybrid Teas, and Hybrid Perpetuals, may be thinned out, if necessary, after flowering in summer. But they must be pruned in March. In April the Teas and Noisettes, both dwarf and standard, and the Banksian roses are pruned. How to prune.—This is a much-disputed subject among rose growers, and as authorities differ widely with regard to it, some advocating hard pruning, and There are, however, sÉcateurs and sÉcateurs—and a poor one is worse than useless. Its blades must be as sharp as a razor, and so accurately set that they make a perfectly clean cut right through, without pinching the branch or tearing the bark. In choosing one, it is well to try it on a sheet of tissue paper. If it cuts the paper like a sharp pair of scissors, it is all right. But if it curls the paper round the blade, instead of making a clean cut, it is to be avoided. After trying many different makes, I have found that the SÉcateur Montreuil, which I have now procured for several years from MM. Vilmorin, Andrieux et Cie., 4, Quai de la Megisserie, Paris, is far the best I can get. It costs 8 francs, and is made in three sizes. As to hard-and-fast rules in pruning, there are but two.
1. Prune weak-growing roses much harder than strong-growing roses. As the object of pruning is to throw the sap into the young shoots which will start from the dormant buds or "eyes," in order to make them flower, a weak-growing rose must be pruned hard so as to concentrate all the vigour of the plant on the few dormant buds we leave. While if we prune a strong-growing rose very hard we only make it throw yet longer shoots, which soon 2. Always prune to a dormant bud which points outwards. This is done to keep the centre of the plant comparatively free, by preventing the shoots crossing and choking each other. In pruning we have to keep two objects ever in view. In the first place we must prune in order to get rid of all dead wood, and weak, unripe and useless shoots, thus enabling the young healthy wood to take their place. And secondly we must prune so as to keep the plant in good shape and good health, by cutting back the strong and healthy wood we leave to a suitable length. If the winter has been mild, we shall find many buds on the upper part of strong shoots of last year's growth, which are already bursting into leaf and even showing a flower bud. And it seems so brutal to destroy these, that I know one is often tempted to leave some to take their chance, instead of hardening one's heart and sternly cutting down to just above the first dormant bud. But when the plants really start in May, we pay for our tender-hearted folly by blind unhealthy shoots which only disfigure the plant, while the real flower shoots are starting below and cannot get up to the light and air. Or, again, the unpruned shoot turns black and begins to die back, and we have to cut it down much further than would have been necessary had we pruned it at the right moment. In pruning, however, let the amateur remember that until he has gained considerable experience in the matter, it is far safer to prune too lightly than to prune in excess. And I must repeat that no rules will really help us, unless we study the special nature and idiosyncrasy of each individual plant, exactly as we study the character of the child we have to deal with. With climbing summer-flowering roses very little pruning at all is required, except slightly shortening the ends of the long rambling shoots, cutting out all the dead wood, and cutting some of the old flowering shoots which are worn out, down to the base. It must be remembered that Ramblers, Noisettes, and other climbing roses bear their flowers on the laterals of the long shoots of the former year. While the Banksias, some of the Multifloras such as Aglaia, and that beautiful rose Fortune's Yellow, only flower on the sub-laterals, i.e. on wood three years old. If therefore these shoots are cut back too hard the plant does not flower. One of the finest specimens of Crimson Rambler I have ever seen, was ruined for several years by an ignorant person who carefully and triumphantly cut out all the long shoots of the former year, which he considered mere "sucker rods." And then he was surprised at the plant bearing no flowers. A certain amount of very useful minor pruning can be carried on all through the summer, by cutting out Cutting off dead blooms.—Though to some it may seem a small matter, much good may also be done to our plants through the summer by the way we remove dead flowers. Instead of merely snapping off each blossom between thumb and finger, it is better to do a little very mild pruning, by cutting each dead blossom off just above the second leaf below it. This greatly promotes the autumn blooming of the plants, and keeps them in good shape. It is a little more trouble, but amply repays us in the end. The precise moment of setting to work must depend to some extent on the weather. Of course we cannot begin in a heavy frost, as that would be fatal to the plants. Nor can I go as far as Mr. Pemberton, who with delightful enthusiasm advises us to choose a cold day with north-east wind and occasional sleet showers. That is too complete a counsel of perfection for most mortals; for however much they love their roses, they equally dread pneumonia for themselves. But Well prepared, therefore, sÉcateur in hand, and knife in pocket in case of need, with strong gloves and old clothes, and if a woman, with a housemaid's kneeling pad to kneel on so as to get more easily at the dwarf plants—for pruning is tiring work in any case, and it is well to save extra fatigue and backache—we now begin on a late February day, with Rugosa Roses.—These need little pruning beyond cutting out the dead wood, and cutting back some of the old wood almost to the base, when it will throw up fresh shoots which will bloom late. The suckers which these roses throw up in numbers, may be cut back to three or four feet to form a thick bush. Ayrshires and Sempervirens.—Thin out slightly and cut out dead wood—no further pruning is needed. Boursaults need no thinning. The flowers are borne on the laterals of last year's long shoots, which may be left six to ten feet long. The Species and most of their hybrids need no pruning beyond cutting out dead wood, and occasionally cutting the young base shoots back to hard, well-ripened wood, when the tips are touched by frost. Provence and Moss Roses.—Cut out old wood; thin out old shoots, and out back the young base shoots and laterals to four or six eyes. Some of the Miniature Provence.—Keep well pruned to within six inches of the ground, and thin out the centre. Gallica and Damask.—Prune lightly. The strong growers may be kept as tall bushes or pillars. The dwarf, such as Red Damask, and Rosa Mundi cut back to three feet. Keep the best one- and two-year-old shoots and laterals, and thin out old and weak wood. Alba.—Grow as bushes or pillars five to six feet high, cutting out weak wood, leaving all the laterals on which the flowers are borne, about eight inches to one foot. Hybrid Chinas, such as Charles Lawson, Coupe d'HÉbÉ and Madame Plantier, should be grown as bushy pillars, leaving the shoots six feet long. Shorten the laterals on old wood to three or four eyes. Blairii No. 2 should hardly be touched. Sweet Briars.—Cut out all weak wood and cut old and naked shoots down to the ground. The Common Sweet Briar should be grown about four feet high. The Penzance Briars make enormous base shoots, which may be shortened to ten feet or less according to one's requirements, and some of the strong laterals of last year shortened back. Lord and Lady Penzance, from their Austrian briar blood, are Hybrid Bourbons.—Prune the laterals lightly, and leave the best of the base shoots. Hybrid Noisettes and Musks.—Thin out old wood and tie in young shoots. Austrian Briars.—Only cut out dead wood. Soleil d'Or, a hybrid, flowers on the young wood, and the shoots may be pruned back to two feet. Scotch Briars.—No pruning is needed, except cutting out old and dead wood and shortening back some of the numerous suckers. Climbing Multifloras need little pruning. When grown as pillars or on screens they are apt to get bare at the base. Therefore it is well to cut some of the weaker young shoots back to two or three feet to clothe the base, leaving the strong ones their full length. With Crimson Rambler and its class, cut out some of the old wood to make room for the young shoots and shorten any weak laterals: but leave most of the strong ones intact, and do not touch the long base shoots of the last year. Wichuraianas.—Only cut out old and dead wood. I have seen a beautiful effect produced with Dorothy Perkins by cutting out all the old wood in the Chinas.—The old Blush and Cramoisie SupÉrieure should only be thinned. The newer kinds, such as Mme. EugÈne Resal, Laurette Messimy, etc., may be cut back to a few eyes from the ground. Bourbons.—Prune lightly, growing as bold bushes or standards; except Hermosa, which may be pruned back to form a dwarf, spreading, two-feet bush; while Mrs. Bosanquet is treated like the Chinas. Noisettes are of two types. The strong growers need hardly any pruning, except MarÉchal Niel, which must have all cankered and weak shoots removed after it has flowered. Lamarque, Fortune's Yellow (which must not be pruned at all), and Jaune Desprez need a wall; and CÉline Forestier prefers one. The other type, such as L'IdÉal and William Allen Richardson, may be pruned fairly close, by cutting back the laterals to a few eyes. All Noisettes bear their flowers on the laterals; therefore these should be preserved as much as possible. Dijon Teas.—These are the climbing and vigorous Banksia Roses.—These need no pruning except in the case of a very old plant, when a shoot that shows weakness may be cut down to the base in April. But I have pointed out in Chapter IV that the Banksias bear their flowers on the sub-laterals of the third year. Therefore, for three years they must not be touched with the knife, and the shoots merely tied in evenly over the surface of the wall. Dwarf Polyanthas.—These only need to have the old flower stems cut out in March. Hybrid Perpetuals and Hybrid Teas, dwarf and standard.—If pruned for garden purposes or what I call enjoyment, not for exhibition, all dead wood and weak or unripe shoots must be cut out to the base of the plant. The centre of the plant must be kept clear by removing shoots which cross each other. The strong ripe shoots from the base should be cut Teas and Noisettes, both dwarf and standard, are pruned on exactly the same lines as the Hybrid Teas and Hybrid Perpetuals, but must be pruned in April instead of March. PROPAGATING ROSES.The three chief methods of propagating roses are by— Budding.—This is the best-known method of propagating. And it is so widely practised by amateurs and gardeners of all degree, that it is better to get an object-lesson in the art than to depend on written instructions. With a little practise any one with neat fingers can bud. But great care must be taken in the operation, not to bruise the bark of the bud or "shield" that is to be inserted in the stock. The best stocks, whether for dwarfs or standards, Dwarf stocks are treated much in the same way, but must be planted nearer the surface than standards; for when they are budded the earth must be removed right down to the roots, in order to set the bud as low as possible, as it is inserted in the stem itself, and not in the young wood of the year. We then choose the "scion"—a twig of the rose we wish to propagate which has already flowered, The stock is now made ready to receive the bud. At the point we have chosen for inserting the bud—in standards let it be as close as possible to the main stem—a perpendicular slit from half an inch to an inch long is made with the budding-knife, care being taken only to cut through the bark and not to wound the wood below. A short cross-cut is made at the top of the slit. Then the bark is gently raised on each side downwards from this cross-cut, with the flat handle of the knife. Into this slit the bud is slipped by putting the pointed lower end into the cross slit, and pushing it down as far as it will go. We then cut off any bark at the top of the bud that overlaps the cross-cut, so With a bit of Raffia grass, well moistened in water, we now bind up the bud; beginning from below with a double turn over one end of the Raffia, and keeping it quite flat, exactly in the way we put on a surgical bandage. When we come to the bud itself, the Raffia must be wound tightly and as close to the eye as possible without actually touching it. When the whole slit is completely and evenly covered, slip the end of the Raffia through the last turn and pull it tight. The operation is now complete. CUTTINGS.Roses on their own roots are grown from cuttings, and it is a system which suits many varieties. How to make a cutting.—Cuttings are taken from well-ripened twigs which have already flowered, or from a lateral upon the main flowering shoot, which has ceased growing without bearing a blossom. They should be from two to six or seven inches in length, with three to nine buds upon them. And judgment is needed regarding these buds in choosing the twig, as we must take one on which they are neither immature nor too fully developed. In the case of a cutting with ten leaves we cut off the top a quarter of an inch above the fourth leaf, and the same distance below the tenth. The four lower leaves are then cut off close to the bud they cover, and the Fig. 3.—Rose cutting with a heel, 4 leaves cut, 2 leaves left. Cuttings are taken in two ways. 1. With a heel; that is a small portion of the wood of the stem from which the twig grows. 2. Without a heel; being cut through just below a bud. Fig. 4.—Rose cutting without a heel, 4 leaves cut, 2 leaves left. Cuttings under glass.—Cuttings of the choice kinds of Teas, Hybrid Teas, Hybrid Perpetuals, and Chinas are raised under glass, taken from pot plants as soon as they have flowered in the spring. The cuttings are put in pots filled with fibrous loam and silver sand, about six in a five-inch pot. When ready Cuttings in the open ground.—This is an interesting and easy way of getting a good stock of many kinds of hardy, strong-growing Perpetuals, Sweet Briars, Ramblers, etc. And it may be successfully carried on from early in August to the middle of October. Cuttings are inserted three inches apart in rows, leaving some ten inches between each row. They may be either set in a trench, or dibbled into a specially prepared bed. I have tried both plans, and find the following very successful. A bit of ground, partially but not too much shaded, is forked up; a layer of good rotten manure laid on it; upon this three inches of leaf mould; on this again three inches of sharp, sandy road-scrapings—silver sand would be as good or better, but here the gravel road-grit is handy. The bed is then stamped down as hard as possible, until it forms a firm solid mass. The cuttings are then inserted in rows—a hole of the right depth for each being made into the compost with a smooth sharp-pointed stick the size of a lead pencil—a long wooden penholder is a good dibble. Into this hole the cutting is thrust till its base rests Many of these cuttings will show flower the next summer. And by November—i.e. fifteen months after planting—they can be lifted and planted out in their permanent quarters. The other plan is to make a little trench eight inches or so deep in good loamy soil, with a layer of silver sand at the bottom. The cuttings are set against the sloped side of the trench, and it is then filled up with soil and stamped in very firmly. I find this answers best for the Penzance Sweet Briars; but personally I prefer the former plan for other roses. The cuttings must be well watered and carefully weeded from time to time, and in the winter must be given slight protection by fronds of bracken or boughs of evergreens laid lightly over them. LAYERING.This is chiefly resorted to when it is wished to increase the stock rapidly of some very choice rose. It can be carried on in summer and early autumn. The directions given in Mr. Rivers' Rose Amateur's Guide of 1843 are so admirable that I quote them in extenso. "About the middle of July in most seasons the shoots will be found about eighteen inches or two feet in length; from these, two-thirds of the leaves should be cut off, close to the shoot, beginning at the base, with a very sharp knife; the shoot must then be brought to the ground, so as to be able to judge in what place the hole must be made to receive it; it may be made large enough to hold a quarter of a peck of compost; in heavy and retentive soils this should be rotten dung and pit sand in equal quantities, well mixed; the shoot must then be 'tongued,' i.e. the knife introduced just below a bud and brought upwards, so as to cut about half way through; this must be done at the side or back of the shoot (not by any means at the front or in the bend), so that the tongue does not close; to make this certain a small piece of glass or thin earthenware may be introduced to keep it open. Much nicety is required to have the tongue at the upper part of the shoot, so as not to be in the part which forms the bow, as it is of consequence that it should be within two inches of the surface, so as to feel the effects of atmospheric heat; unless this is attended to the roots will not be emitted quickly; the tongued part must be placed in the centre of the compost, and a moderate-sized stone put on the surface of the ground to keep the layer in its place. |
