Content Detail

Practice correct pruning techniques and learn which plants to prune now and, more important, which to prune later. Known as dormant pruning, thoughtful removal of branches in winter is easy and encourages proper spring growth. 

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. 

COVID-19 Precautions: Program participants must abide by the Arboretum’s safety guidelines

Eric Schroeder, horticulturist, The Morton Arboretum

Branching above, tip-rooting below: Eric’s earliest memories include an affinity for the outdoors, yet he deviated into the digital realm of virtual environments for fourteen years before the allure of fresh air and photosynthesis drew him back out into the sunlight to join the grounds crew at The Morton Arboretum, where he has maintained trees, shrubs, and perennial trial gardens since 2013.


Your support is vital to the Arboretum, where the power of trees makes a positive impact on people’s lives.
