As a rule the flowering plants, such as geraniums and heliotropes, require more light and sunshine than those grown for foliage, such as palms, ferns and the decorative leaved begonias. It is almost impossible, during the winter months, to give any of them too much sunlight and where there is any danger of this, as sometimes happens in early fall or late spring, a curtain of the thinnest material will give them ample protection, the necessity being not to exclude the light, but simply to break the direct action of the sun's rays through glass.
A great variety of plants may be grown in the ordinary window garden, for which the sunniest and broadest window available should be selected. There are two methods of handling the plants: they may be kept as individual specimens in pots and "dishes" or "pans" (which are nothing more or less than shallow flower pots), or they may be grown together in a plant box, made for the purpose and usually more or less decorative in itself, that will harmonize with and set off the beauty of the plants.
The latter method, that of growing in boxes, offers two distinct advantages, especially where there is likely to be encountered too high a temperature and consequent dryness in the air. The plants are more easily cared for than they are in pots, which rapidly dry out and need frequent changing; and effects in grouping and harmonious decoration may be had which are not readily secured with plants in pots. On the other hand, it is not possible to give such careful attention to individual plants which may require it as when they are grown in pots; nor can there be so much re-arrangement and change when these are required--and what good housekeeper is not a natural born scene shifter, every once in so often rolling the piano around to the other side of the room, and moving the bookcase or changing the big Boston fern over to the other window, so it can be seen from the dining-room?
If the plants are to be kept in pots--and on the whole this will generally be the more satisfactory method--several shelves of light, smooth wood of a convenient width (six to twelve inches) should be firmly placed, by means of the common iron brackets, in each window to be used. It will help, both in keeping the pots in place and in preventing muddy water from dripping down to the floor or table below, if a thin, narrow strip of wood is nailed to each edge of these shelves, extending an inch or two above them. A couple of coats of outside paint will also add to the looks and to the life of these shelves and further tend to prevent any annoying drip from draining pots. Such a shelf will be still further improved by being covered an inch or two deep with coarse gravel or fine pebbles.
