WINDOW BOXES
Many garden plants should be started in a box of earth in a warm, sunny window. In some schools this can be done with a little care in heating on cold nights. Small boxes or grape baskets full of rich sandy loam with an inch of gravel in the bottom for drainage may be used. Sow the seeds in rows or broadcast. To prevent the soil from drying out too quickly, cover the box with a pane of glass. When the plants are up, give them plenty of light and not too much warmth. On very mild days set them in a warm, sheltered place out-of-doors and bring them in again early in the evening. This tends to make them hardy. When about three inches high, pick the young plants out and set them in other boxes a few inches apart. This moving causes the formation of numerous fibrous roots and makes stronger plants.
