Divided bulbs can be replanted immediately or stored in a dry, cool area for replanting in the fall. Discard any bulbs that appear diseased. A common and frustrating problem of bulbs is failure to bloom. This can have several causes. Bulbs may rot in soils that stay wet for a long time.
Good drainage is essential.
Bulbs may stop blooming if they become overcrowded or shaded too heavily. Sparse blooms on daffodils can be caused by planting too shallowly. If leaves are cut off too soon in spring, the bulb may not store enough food to bloom the following year. Many varieties of bulbs will not produce flowers a second year in Southern climates. Animals often dig and eat tulip and crocus bulbs during the winter.
