What’s the best time to plant evergreens?
planting evergreens and other trees in the fall allow the tree to establish roots underground before spring arrives. In the spring, plants and trees are focused on growth above ground and on producing new leaves or needles. Both experts warn against planting evergreens such as boxwoods, evergreen magnolias, andromeda, nandina, arborvitaes, and rhododendrons in the fall. The dry and windy conditions of the fall make these plants more susceptible to drought stress, meaning they’re less likely to survive the winter.
