Before selecting the location to plant bulbs in the
landscape, consider the light requirements of the plant.
Does the plant require full sunshine, partial shade or full
shade? Since early spring bulbs
bloom before most trees or shrubs leaf out, they
can successfully be planted under trees and shrubs. Many summer blooming bulbs
require full sun or partial shade. Spring bulbs planted on a south slope will bloom earlier than
the same bulbs planted on a north slope. Spring
bulbs planted on a hillside will bloom earlier than
bulbs planted in a valley. Cold air is heavier than warm
air and behaves like water. It flows down the slope,
settling in the low areas.
