During this month every part of the Green-house should have a thorough cleansing, which is too frequently neglected, and many hundreds of insects left unmolested. To preserve the wood work in good order, give it one coat of paint every year. Repair all broken glass, white-wash the whole interior, giving the flues two or three coats, and cover the stages with hot-lime, white-wash, or oil-paint; examine ropes, pullies, and weights, finishing by washing the pavement perfectly clean. If there have been any plants in the house during summer, be sure after this cleansing that they are clean also, before they are returned to their respective situations.

OF WATERING.

The intensity of the heat being over for the season, the heavy dews during night will prevent so much absorption amongst the plants. They will, in general, especially by the end of the month, require limited supplies of water comparatively to their wants in the summer months. Be careful amongst the Geraniums that were repotted in August, not to water them until the new soil about their roots is becoming dry. Syringing in this month may be suspended in time of heavy dews, but in dry nights resort to it again.

The herbaceous plants and those of a succulent nature must be sparingly supplied. The large trees that were put in new earth will require a supply only once a week, but in such quantity as will go to the bottom of the tubs.

PREPARING FOR TAKING IN THE PLANTS.

About the end of the month all the plants should be examined and cleaned in like manner as directed for those of the Hot-house last month, which see. From the 1st to the 8th of October is the most proper time to take them into the Green-house, except those of a half hardy nature, which may stand out till the appearance of frost. All the Geraniums that were put in the shade after shifting, may after the 10th be fully exposed, which will in some degree prevent them from being weak. Turn them in such a manner as will make them grow equally. Always endeavour to have these plants short and bushy, for they are unsightly otherwise, except where a few very large specimens are desired for show. All Myrtles and Oleanders that were headed down, if the young shoots are too crowded, continue to thin them out, and give regular turnings, that all the heads may grow regularly.

STOCKS AND WALL-FLOWERS,

That are wanted to flower in the Green-house (where they do remarkably well) and are in the ground, have them carefully lifted before the end of the month, and planted in six or seven inch pots, with light loamy soil. Place them in the shade till they take fresh root, and give them frequent sprinklings of water. As soon as the foliage becomes erect, expose them to the full sun, and treat as Green-house plants.

CHRYSANTHEMUMS.

These very ornamental plants blooming so late, and at a period when there are few others in flower, one of each variety (or two of some of the finest) should be lifted and put in 8 inch pots, in light loamy soil, and treated as above directed for Stocks, &c. These will flower beautifully from October to December, and when done blooming the pots may be plunged in the garden, or covered with any kind of litter, until spring, when they can be divided and planted out.

CAPE AND HOLLAND BULBS.

About the end of this month is the period for all of these that are intended for the Green-house to be potted. We specified some of the former last month, and will here enumerate a few others.

BabÌana, a genus of small bulbs, with pretty blue, red, and yellow flowers. B. distÍca, pale blue flowers in two ranks. B. strÍcta, flowers blue and white. B. tubiflÒra is beautiful, colour white and red. B. plicÀta has sweet-scented pale blue flowers. There are about twenty species of them, and they grow from six to twelve inches high. Four inch pots are sufficient for them.

GladÌolus, Corn-flag, a genus of above fifty species. There are several very showy plants amongst them, and a few very superb. G. floribÚndus, large pink and white flowers. G. cardinÀlis, flowers superb scarlet, spotted with white. G. byzantÌnus, large purple flowers. G. blÁndus, flowers of a blush rose colour, and handsome. G. cuspidÀtus, flowers white and purple. G. psittÁcinus is the most magnificent of the genus, both in size and beauty of flower; the flowers are striped with green, yellow, and scarlet, about four inches diameter, in great profusion, on a stem about two feet high, and though rare in Europe may be seen in some collections in this country. The beauty of this genus is all centred in the flowers; the leaves are similar to Iris.

Ixia, a genus containing about twenty-five species of very free-flowering bulbs. I. monadÉlpha, flowers blush and green. I. leucÁntha, flowers large, white. I. capitÀta, flowers in heads of a white and almost black colour. I. cÒnica, flowers orange and velvet. I. columellÀris is beautifully variegated with purple, blush, and vermilion colours. The flower stems are from six to twenty-four inches high.

SparÁxis, a beautiful genus of twelve species, closely allied to the last, but more varied in colour. S. grandiflÒra striÀta is striped with purple ground blush. S. versÍcolor, colours crimson, dark purple, and yellow. S. anemonÆflÒra is of various colours, and very similar to AnemÒne.

TritÒnia, a genus of about twenty-five species. Few of them deserve culture in regard to their beauty. T. crocÀta is in our collections, as I. crocÀta, which is amongst the finest, and T. zanthospÌla has white flowers curiously spotted with yellow.

WatsÒnia, a genus containing several species of showy flowers, several of which are in our collections, under the genus GladÍolus, but the most of the species may easily be distinguished from it by their flat shell formed bulbs. W. iridifÒlia is the largest of the genus, and has flowers of a flesh colour. W. rÒsea is large growing, the flowers are pink, and on the stem in a pyramid form. W. humilis is a pretty red flowering species. W. fÚlgida, once Antholyza fÚlgens, has fine bright scarlet flowers. W. rÙbens is an esteemed red flowering species, but scarce.

These six genera are in general cultivation. There are several of others of merit that our limits will not admit of inserting. We have no doubt there are some splendid species that have not come under our observation, and others which may be obtained from the Cape of Good Hope not known in any collection. Many hundreds of superb bulbs indigenous to that country, and of the same nature and habit of the above, have not been seen in collections. The flowers of those which we have specified are from one to four inches in diameter, ringent, tubular, or campanulate. Pots from four to seven inches diameter, according to the size of the roots, will be large enough. Give them very little water until they begin to grow; then supply moderately, and keep them near the light. Of the Holland or Dutch bulbs, the Hyacinth is the favourite to bloom in the Green-house. A few of the Tulip, Narcissus, Iris, and Crocus, may for variety be also planted with any other that curiosity may dictate. When these are grown in pots, the soil should be four-eighths loam, two-eighths leaf mould, one-eighth decomposed manure, one-eighth sand, well compounded; plant in pots from four to seven inches, keep the crown of the bulb above the surface of the soil, except of the Tulip, which should be covered two inches. When these roots are potted, plunge them in the garden about three inches under ground; mark out a space sufficient to contain them; throw out the earth about four inches deep, place the pots therein, covering them with earth to the above depth, making it in the form of a bed. Leave a trench all round to carry off the rain. By so doing, the bulbs will root strong, the soil will be kept in a congenial state about them, and they will prove far superior than if done in the common method. Lift them from this bed on the approach of frost, or not later than the second week of December, wash the pots and take them to the Green-house.

OF REPOTTING.

VibÚrnum. This is a good period to repot all the flowering plants of this genus. For a full description of them, see Green-house, March. The repotting is only intended for young plants that are wanted to grow freely. When the V. tÌnus is much encouraged, it does not flower profusely.

LÌlium, Lily. There are four species of this splendid genus kept in the Green-house. It has always been our practice to repot them when they begin to grow, though it is said by some that, when removed at that time, they will not flower perfectly. They will not do to be kept above a few weeks out of the ground, and we think they ought never to be kept out any period. We place them here, that a choice may be made by the cultivator of either of the periods, which is not material; observing in either case, that excess of moisture is injurious while they are dormant. L. longiflÒrum grows about one foot high, with one or more flowers. L. longiflÒrum suavÈolens, is sweet-scented, and has only one flower. L. japÒnicum is the most magnificent, grows about two feet high, with three or more flowers on one stem. L. lancifÒlium; we incline to class this with L. speciÒsum, there being no apparent distinction in any character. The flowers are all of the purest white. They require from five to seven inch pots.
