Introduction to Pruning (online and in person)

Practice correct pruning techniques and learn which plants to prune now and, more important, which to prune later.

Content Detail

Known as dormant pruning, thoughtful removal of branches in winter is easy and encourages proper spring growth. In this class at The Morton Arboretum, you will complete a short online component at your convenience before the in-person session. In-person class time will be spent in the field 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 a self-paced online component and an on-site session.
