Rooms
FEBRUARY
At this season, the plants call for the most assiduous attention. If the stage has been made according to our description, in very cold nights it should be drawn to the centre of the room, or at least withdrawn from the window, observing every night to close the window tight by shutters, or some substitute equally as good. And, if the temperature begins to fall below 34°, means should be adopted to prevent it, either by putting a fire in the room, or opening any adjoining apartment where fire is constantly kept. This latter method is the best where it is practicable, and ought to be studied to be made so.
Some, very injudiciously, in extreme frosts put into the room, where there is no chimney, amongst the plants, a furnace of charcoal, in order to heat the room. The effect is, that the foliage becomes dark brown, and hardened like, and many of the plants die, the rest not recovering until summer.
Watering may be attended to according to the directions of January, only observing that those that begin to grow will absorb a little more than those that are dormant.
Roses, especially the Daily, if kept in the house, will begin to show flower buds. Use means to kill the Green-fly that may attack them.
Hyacinths and other bulbs must have regular attendance in tying up, &c. Take care not to tie them too tight, leaving sufficiency of space for the stem to expand. Give those in the glasses their necessary supplies, and keep them all near the light. Never keep bulbous roots while growing under the shade of any other plant.
Camellias, with all their varied beauties, will, in this month, make a splendid show. Adhere to the directions given in the previous month, and so that new varieties may be obtained, (see Green-house, February, under the head of Camellia,) which directions are equally applicable here. When the flowers are full blown, and kept in a temperature between 34° and 44°, they will be perfect for the space of four, five, and frequently six weeks, and a good selection of healthy plants will continue to flower from December to April.
Be sure that there is air admitted at all favourable opportunities. Give a little every day that there is sunshine, if it is only for a few minutes.
Hot-House
MARCH
If this department has been regularly attended to, the plants will be in a fresh healthy state. Where there is any sickly appearance, heat has been deficient, or insects of a destructive character are preying upon them. Too much water at the root frequently causes the foliage to become yellow. It will add greatly to their general improvement, to syringe the whole twice or three times a week, observing to do it in the morning about sunrise; and it is highly necessary that the water that is used should be of the same temperature as the house; and at all times, whatever water is given to the roots, the same must be observed. For airing, see last month, observing, as the season advances, to increase the quantity.
Continue to fumigate when any of the Green-fly appears, (see January for directions,) and where there are any of the plants infected with the white scaly insect, clean them as there directed. If overlooked for a few months, they will be increased tenfold. Very frequently, where there are only a few, they are neglected until the plant is overrun with them, and then it may be said, it is impossible to dislodge them entirely. Clear off all decayed leaves from the plants. These will have made fresh shoots, and the decayed leaves very much disfigure the whole collection. We would not have repeated this observation, if it was not an essential point, and one which is so frequently neglected.
OF SHIFTING PLANTS
Those Alstrœmèrias that are growing freely, and in small pots, should be put into pots of a larger size. This genus of plants will not flower except they are encouraged with frequent shifting: they are all beautiful.
Green-House
MARCH
The plants in this compartment will begin to assume a different aspect, and air must be admitted every day if practicable, giving large portions in sunshine by the sashes regularly over all the house, opening those of the front a little, and likewise the doors in fine mild days. To perform this judiciously, give a little about eight or nine o'clock, more at ten, and the whole from eleven till twelve o'clock, shutting again by degrees.
Fire heat will now be dispensed with, but in frosty nights have the shutters on about sundown. The sun is now powerful, and the house can be early shut up in the afternoon, and will gain as much natural heat as will keep up the required temperature, viz. 36° to 40°. Perhaps there may be uncommonly cold weather; at such times be attentive to ward off danger by applying artificial heat.
OF WATERING
Look over the pots and tubs at least every alternate day, to see where water is wanted. In watering, too much caution cannot be used, especially during winter and the commencement of spring. It was observed last month what would be the effect of too much water. It may be remarked, that if the exterior of the pot is very damp, the soil inside is too wet, and in that state is uncongenial to vegetation, which now begins to start, and ought by all possible means to be encouraged. People may be frequently observed watering all plants indiscriminately, not taking the trouble to look into or feel the state of the soil in the pots or tubs, and by going over them three or four times in this manner will be sufficient to put the plants in such a state, that they will not be recruited for some months. Hence the reason of so many sickly plants.
Caméllias, where there are collections, will continue to flower. Treat them according to the directions given last month.
OF ORANGES, LEMONS, &c
Be sure they are not too wet, as too much humidity as well as aridity causes their foliage to have a yellow appearance, with this difference, that in the former case the foliage is the same to the touch as when green; but in the latter, it is soft and dry. We have observed trees in tubs and half barrels, with holes all round their sides. This is a ludicrous idea, having the appearance of keeping the water from reaching the bottom of the tub or barrel. For the best kind of tub for large trees, see August under this head. If any of the trees have stunted, straggling, or irregular heads, about the end of this month, or beginning of next, head or cut them down to the shape desired. The old wood will push fresh shoots. You may cut close, or shorten less or more, according as you desire young shoots to arise; at the same time observe that you do not cut below the graft or inoculation. Trees thus headed down should be kept until May, and then planted in the garden, (see May,) or if that cannot be done, turn it out, and reduce the ball of earth by probing with a pointed stick all round the sides and bottom of the ball, cutting off any very matted roots. If any of the roots are decayed, cut them into the sound wood. By being thus reduced, it will go into the same pot or tub if not a less one. Having a good supply of fresh earth ready, put a few inches in the bottom of the pot or tub, place the tree therein, and fill all round, at the same time pressing it down with the hand or a stick. Give very little water until there are signs of vegetation.
MYRTLES, OLEANDERS, &c
These, with similar exotics, may be treated as above. If any of them have been infected with the scaly insect, after heading down, &c. scrub the remaining stems with a strong decoction of tobacco, heated to about 100°. Afterwards clean with soap and water.
