March and April are excellent months to
plant dormant trees and shrubs, once the snow is gone and the frost is
out of the ground.
By planting trees and shrubs before they've leafed out, they have the
opportunity to wake up naturally and get accustomed to their new
surroundings without the heat and water stress experienced in the
summer. The plants benefit, and so will you when you see how much
cheaper dormant plants are than their leafed-out counterparts.
When planting a tree or shrub in a grassy area, remove the lawn grasses
surrounding the base of the tree to avoid competition between the roots
of grasses and your new tree. Add mulch to help retain moisture.
