СКАЧАТЬ compounded, and prescriptions recommended, for the destruction of these nefarious pests. Many of them are altogether ineffectual. Of receipts specified in works of this kind, not a few of them (though eagerly sought for) by men of extensive practice, have been rejected. We shall give the most simple, and in part effective receipt for the destruction of the Green fly.

      Take a large tub of soft water, (if the day is frosty, it had better be done in the house,) invert the plant, holding the hand, or tying a piece of cloth, or any thing of the kind, over the soil in the pot, put all the branches in the water, keeping the pot in the hand, drawing it to and fro a few times; take it out, and shake it. If any insects remain, take a small fine brush, and brush them off, giving another dip, which will clean them for the present. As soon as they appear again, repeat the process—for nothing that we have found out, or heard of, can totally extirpate them.

      OF BULBOUS ROOTS IN GENERAL.

      If you have retained any of the Cape bulbs from the last planting, let them be put in, in the early part of the month. For method, see September. Those that are growing must be kept very near the light, that is, close to the window, or they will not flourish to your satisfaction. The fall-flowering oxalis may be kept on the stage, or any other place, to give room to those that are to flower.

      Hyacinths, Jonquils, Narcissus, Tulips, &c. will keep very well in a room where fire heat is constantly kept, providing that they are close to the window. A succession of these, as before observed, may beautify the drawing room from February to April, by having a reserved stock, in a cold situation, and taking a few of them every week into the warmest apartment.

      Wherever any of the bulbs are growing, and in the interior of the room, remove them close to the light, observing to turn the pots or glasses frequently to prevent them from growing to one side, and giving them support as soon as the stems droop, or the head becomes pendant. The saucers under the Hyacinth and Narcissus especially may stand with water, and observe to change the water in the glasses, as already mentioned.

      Every one that has any taste or refinement in their floral undertakings, will delight in seeing the plants in perfection; to have them so, they must be divested of every leaf that has the appearance of decaying—let this always be attended to.

FEBRUARY.

       Table of Contents

      In the early part of this month the weather generally is very cold and changeable in the middle states, and strict attention, with the greatest caution, will require to be paid to the management of the Hot-house. Most of the tropical plants commence an active state of vegetation; and if checked by temperature or otherwise, they will not recover until midsummer. The thermometer may be kept two or three degrees higher with fire heat than last month; the sun will be more powerful, and this will, in a great degree, increase the vigour of the plants. Air may be admitted when the thermometer rises to 75° or 80°, not allowing it to rise higher than the latter. In giving air, let it be done by the top sashes. It is improper to give it in any way to cause a current, for the external air is very cold, although the sun is more powerful. An inch or two on a few of the sashes, as has been previously observed, will be effectual in keeping the temperature low enough, except the weather is very mild.

      With regard to firing, what was said last month may suffice for this. Always recollect that it is preferable to keep out the cold than to put it out. It will frequently happen in the time of intense frost, that the weather is dull. In such cases fire in a small degree is requisite all day.

      Heavy snows ought never to be allowed to remain on the shutters while they are on the house. If the snow lies on the sashes one day, the internal heat will dissolve some of it; night coming on will freeze it to the wood work, when it will become a solid mass, and too frequently cannot be separated without much damage. If allowed to remain on for two days, the plants are very much weakened, and the foliage discoloured. Therefore let the snow be cleared off instantly, that no inconvenience may take place.

      It will be observed that plants absorb more water this month than last. The quantity given will require to be increased, according to the increase of vegetation and the advancement of the season; but never give it until the soil begins to get dry, and then in such proportion as will reach the bottom of the pot. After the sun has got on the house in the morning is the best time to water, observing all the directions given in January.

      OF INSECTS, &c.

      Perhaps sufficient observations were given under this head last month; but the importance of keeping these disagreeable visitors out of the house, constrains us to make a few more remarks, and perhaps it may be necessary every month. Man cannot be too frequently guarded against his foes, more especially when they are summoning all their forces, and no profession has more than that of the Horticulturist. Let a strict examination be made about the end of the month for the Red spider; they will be in operation some weeks before their depredations are observed on the foliage. The under side of the leaf is their resort in the first instance, and on such plants as have been already mentioned.

      Observe daily the young shoots, in case the Green fly becomes numerous. They give the foliage a very disagreeable appearance, and with most people it is intolerable, before their career is arrested. It also takes a stronger fumigation, which has frequently to be repeated the following day to the same degree, much to the injury of many of the plants, and adding to the disagreeableness of the continued vapour in the house.

      OF SHIFTING PLANTS.

      The Calceolàrias that were put in small pots about the beginning or middle of last month, will, if they have done well, require, about the end of this, to be put in pots a size larger.

      If any of Lilìum longiflòrum, Speciòsum, or Japónicum, are wanted to flower early, and were put in the Hot-house in December, without dividing, those that are to flower will have pushed their flower stems, and can be separated from those that will not flower, and put singly into pots; the two former into five or six inch pots, while the latter require six or seven inch pots. Of those that do not flower, three or four can be put into one pot.

      About the end of the month, some of the plants of Eurcúma, Amómum, Kæmpféria, Glóbba, Phrynium, Cánna, Zíngiber, Hedychium, and others that are on the dry shelf, will be offering to grow. Let them be taken out of their pots, some of their weakest shoots or tubers taken off, and the strong ones repotted: give gentle waterings until they grow freely, then give an abundance.

      Dionæa mucípula, or Venus fly trap, grows best in the Hot-house, and will, about the end of the month, stand in need of being repotted. This plant is very seldom grown in any degree of perfection, having been always considered a delicate plant in collections. The operator has never had courage to treat it according to its nature in a cultivated state. If it is taken out of the pot, just when beginning to grow afresh, and divested of all the soil, leaving only a few of the young roots, (it is a bulb, and will receive no injury by so doing,) put it in new soil; when potted, place the pot in a saucer with one inch of water in it, giving always a fresh supply, when necessary. A shady and moist situation is best adapted to it; this being repeated every year, it will grow, flower, and seed in СКАЧАТЬ
