Practice correct pruning techniques and learn which plants to prune now and, more important, which to prune later. The colder months are an excellent time to prune most trees and shrubs. Known as dormant pruning, thoughtful removal of branches during this period is easy and encourages proper spring growth.
In this interactive class at The Morton Arboretum, you will complete a 60-minute online component on your own before attending an in-person session. Spend the in-person session outdoors with an expert who will demonstrate what to prune and how to do it. Then put on your gloves, grab some pruners, and try it yourself.
This program includes self-paced online components and an in-person session.
