Bulbs, tubers and corms
Bulbs are fleshy underground protuberances of leaves, stems or roots. Actually, "bulb" is a generic term, and some of these underground protuberances, all of which will grow into full plants, are more correctly called "corms" or "tubers." Tubers are thickened stem sections, covered with modified buds; corms are also underground stem sections, but without bud.
Some of loveliest flowers are bulbs, and gardeners rely on them heavily because they bloom in such profusion with little care or cultivation. They are among first blooms of early spring, with diminutive snowdrop, for example, appearing in early March.
Here is answer to; where can I find information about planting bulbs? Bulbs should be planted from 3 to 6 inches deep, and, as a rule of thumb, larger bulb, deeper it should be planted. (Both tubers and corms are treated similar to bulbs.) Using a spade, a slice is dug in soil to required depth, bulbs placed in hole and sod replaced. If soil is poor, a sprinkling of bone meal is added and mixed with soil at bottom of hole.
Each spring, flowering bulbs should be well-fertilized. (Use manure and chemical fertilizer.) Care must be taken to keep fresh manure away from roots or bulb or tuber itself. The fertilizer should be worked well into soil. The soil itself should be cultivated to a depth of 3 to 4 inches each week.
During blooming season, it is a good idea to cut off most of buds to get bigger and showier flowers. Watering regularly is essential, and when soil gets too dry, punching a few holes in it around plant will help get much-needed moisture down near roots.
