Depth to Plant
A good rule for the depth to plant bulbs is twice their length; but sometimes it pays to plant them deeper to protect them.
If planted deeper they come into bloom a little later, but the protection of the depth may save them from destructive freezing.
Where to Plant Bulbs
Blooms of bulbs look beautiful anywhere. One need not hesitate to place them in masses (a number near each other) in the garden borders, for after they bloom and die down, there will be no bare spots if some annuals, with short roots, are grown over them; such as alyssum, ageratum, violas, verbenas.
Plant the low-growing sorts of bulbs in the front, and the taller kinds in the back of the garden.
Cover, when the ground begins to freeze, with several inches of dry leaves or grass.
Most bulbs do best if not lifted after blooming; that is, let them be in the ground for several years. Then the new bulbs which have grown on the old ones will need to be separated and planted.
Narcissus and daffodils may remain many years without disturbing.
