Plants that are kept in rooms generally are such as require a medium temperature, say 40°. Sitting rooms or parlours, about this season, are, for the most part, heated from 55° to 65°, and very seldom has the air any admittance into these apartments, thus keeping the temperature from 15° to 25° higher than the nature of the plants requires, and excluding that fresh air which is requisite to support a forced vegetative principle. Therefore, as far as practicable, let the plants be kept in a room adjoining to one where there is fire heat, and the intervening door can be opened when desirable. They will admit sometimes of being as low as 33°.

If they be constantly kept where there is fire, let the window be opened some inches; two or three time a day, for a few minutes, thereby making the air of the apartment more congenial, both for animal and vegetable nature.

WATERING, &c

There are very few plants killed for want of water, during winter. All that is necessary is merely to keep the soil in a moist state, that is, do not let it get so dry that you can divide the particles of earth, nor so wet that they could be beat to clay. The frequency of watering can be best regulated by the person doing it, as it depends entirely upon the size of the pot or jar in proportion to the plant, whether it is too little or too large, and the situation it stands in, whether moist or arid. Never allow any quantity of water to stand in the flats or saucers. This is too frequently practised with plants in general. Such as Cálla Æthiòpica, or African Lily, will do well, as water is its element, (like Sagittària in this country;) and the Hydrángea horténsis, when in a growing state, will do admirably under such treatment. Many plants may do well for some time, but it being so contrary to their nature, causes premature decay; a fœtid stagnation takes place at the root, the foliage becomes yellow, and the plant stunted; and in the winter season, death will ensue.

OF CAMELLIA JAPONICA

In rooms the buds of Camellias will be well swelled, and on the Double White and Double Variegated sorts, perhaps they will be full blown. While in that state the temperature should not be below 34°; if lower they will not expand so well, and the expanded petals will soon become yellow and decay. If they are where there is fire heat, they must have plenty of air admitted to them every favourable opportunity, or the consequence will be, that all the buds will turn dark brown, and fall off. It is generally the case, in the treatment of these beautiful plants in rooms, that through too much intended care they are entirely destroyed. In the city, they do not agree with confined air, and they cannot get too much of pure air, if they are kept from frost or cutting winds. To sponge frequently will greatly promote the health of the plants, and add to the beauty of their foliage, as it prevents the attacks of mildew. In this season they do not require much water at root, which may be observed in the slight absorption by the soil. See this subject under the head of Watering.

When the flowers are expanded, and droop, tie them up neatly, so that the flower may be shown to every advantage.

OF INSECTS, &c

Insects of various kinds will be appearing on your plants. For method of destruction see Hot-house, January. It will not be agreeable to fumigate the room or rooms, or even to have the smell of tobacco near the house from this cause.

Many ingredients have been 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.
