March is pruning month!
There’s plenty to do in the garden again in March, especially when it comes to pruning. You can prune a wide variety of plants and shrubs in March. You should have already pruned deciduous trees and fruit trees during the winter. Now it’s time to tackle a wide variety of shrubs, ornamental grasses, and perennials. At the beginning of the month, prune plants that are hardy and those that need to be cut back severely. Later in March, you should also prune plants that you’re shaping and plants that might suffer frost damage if you prune them too early.

It’s usually best to wait a little longer before pruning hedge plants as well.
