It is difficult to grow plants in rooms lighted by gas, as the burning gas vitiates the atmosphere. Most living-rooms have too dry air for plants. In such cases the bow window may be set off from the room by glass doors; one then has a miniature conservatory.
While keeping the plants at a suitable temperature, we must not forget that plants love moisture, or a humid atmosphere, and that our living-rooms ordinarily are very dry. A pan of water on the stove or on the register and damp moss among the pots, will afford plants the necessary humidity.
The foliage will need cleansing from time to time to free it from dust. A bath tub provided with a ready outlet for the water is an excellent place for this purpose. The plants may be turned on their sides and supported on a small box above the bottom of the tub. Then they may be freely syringed without danger of making the soil too wet. It is usually advisable not to wet the flowers, however, especially the white waxen kinds, like hyacinths. The foliage of Rex begonias should be cleansed with a piece of dry or only slightly moist cotton. But if the leaves can be quickly dried off by placing them in the open air on mild days, or moderately near the stove, the foliage may be syringed.
The window-box in the room will be seen near at hand, so may be more or less ornamental in character. The sides may be covered with ornamental tile held in place by moulding; or a light lattice-work of wood surrounding the box is pretty. But a neatly made and strong box of about the dimensions mentioned on page 242, with a strip of moulding at the top and bottom, answers just as well; and if painted green, or some neutral shade, only the plants will be seen or thought of. Brackets, jardinieres and stands may be purchased of any of the larger florists.
The window-box may consist of merely the wooden box; but a preferable arrangement is to make it about eight inches deep instead of six, then have the tinsmith make a zinc tray to fit the box. This is provided with a false wooden bottom, with cracks for drainage, two inches above the real bottom of the tray. The plants will then have a vacant space below them into which drainage water may pass. Such a box may be thoroughly watered as the plants require without danger of the water running on the carpet. Of course, a faucet should be provided at some suitable point on a level with the bottom of the tray, to permit of its being drained every day or so if the water tends to accumulate. It would not do to allow the water to remain long; especially should it never rise to the false bottom, as then the soil would be kept too wet.
