As a general thing bulbs will have to remain in cold storage at least six weeks before it will be safe to bring them to the windows in which they are to bloom. But no definite time can be assigned. One must examine the plants from time to time, and on no account should they be taken to the light until the pot is filled with roots and indications of top growth are seen.

It may sometimes be necessary to water them while in the dark room, but as a general thing one watering—the one given at potting-time—will be sufficient. Too much water while in the dark may cause serious trouble. But this, like the length of time allowed for root formation, is a matter that must be left largely to the good judgment of the grower.

When plants have been brought from the cellar, or wherever they have been placed while roots were forming, they should not be put into very warm rooms. Too much heat, combined with the effects of light and water, will result in rapid growth, which is not a healthy one. In warm rooms the flowers will be short-lived.

I have spoken of planting for a succession of bloom. This is important if you want flowers throughout the winter. Pot a few at intervals of ten days or two weeks, beginning the middle of September or first of October. If this is done it is an easy matter to keep the window supplied with flowers from the holidays to the advent of spring. A little calculation will enable one to plant enough to meet the demand and to regulate the planting intervals in such a manner as to bring about the succession necessary to cover the season.

What has been said above may seem so elaborate to the person who has never grown bulbs for winter flowering that it may give the impression that what is really a simple matter is too difficult for the amateur. But if what I have written is read over carefully and given a little thought you will readily see, I think, that most of what I have said has been devoted to giving reasons for the treatment outlined, so that the "whys and wherefores" may be understood. And it will be seen that it all resolves itself into a very simple proposition—viz., good stock, good soil, and cold storage until roots have formed—the three essentials spoken of at the beginning of this chapter. Nothing is required that the beginner in floriculture is not equal to. Potting the bulbs is a much simpler matter than potting a plant, and the preparation of soil for them involves no more labor or skill than the preparation of a soil for a geranium to grow in.

Now as to kinds to grow. I advise the Holland hyacinth, preferably the single varieties; the Roman hyacinth, the white variety only; early tulips; and five varieties of the narcissus—Van Sion, Horsfeildii, empress, trumpet-major, and paper-white—and the Bermuda, or, as it is more commonly called, Easter lily.

The double Holland hyacinths are too double to be pleasing to a person who likes individuality in a flower. The Roman hyacinth is more graceful than any other member of the family. The early tulip is much surer to bloom well than any of the others described in the florist's catalogue.

The Easter lily requires a treatment somewhat different from that advised for the other bulbs. It sends forth two sets of roots, one from the base of the bulb and one from the stalk sent up from the bulb. In order to give each set of roots a chance we have to set the bulb deep down in the soil. Let the pot be only half filled with earth when the lily is put into it, press it down as directed for the other bulbs, and add no more soil until growth begins. Then, as the stalk reaches up, put more soil into the pot, and continue to do this until it is full. In this way give the two sets of roots the support they need.

If bone meal is used as a fertilizer, be sure to get the finely ground article. Coarse bone meal is not what you need, as it does not give an immediate effect.
