Online Renewal Pruning Class and Demonstration

March 13, 2021 @ 9:00 am - 11:30 am UTC-4

Want to maximize the production of flowers and fruits from your shrubs? Renewal pruning is the way to do it. This simple technique works with the natural cycle of replacing old stems with new. This class will start with classroom explanations of the nature of shrubs, the reason for and the techniques of renewal pruning, the tools of the trade as well as demonstrations of this technique. This will be followed by actual demonstration of the technique on shrubs in the Arboretum with some hands-on experience for class participants.

Renewal Pruning: A Definition
Renewal pruning is a method of pruning that works with the natural life cycle of certain shrubs. It is an essential skill for gardeners growing many common shrubs. It is an easily understood and mastered process once learned. And might even end up being one of your favorite garden tasks as you work to maximize the productivity and beauty of the shrubs under your care.

Renewal pruning is appropriate to the vast majority of deciduous flowering shrubs, as well as blackberries, raspberries, and other brambles as well as blueberries. A few ornamental shrubs for which this pruning is appropriate include Abelia, Buddleia (butterfly bush), Callicarpa (beautyberry), Forsythia, Hydrangea, and many others, including some woody vines.

The class includes instruction on the underlying principles and actual demonstrations. Participants will have a chance to prune some shrubs in the Arboretum. Bring your questions (and your pruners).

About This Class
Most of this class will be offered live and online, however, a portion of this program will use videos that were recorded specifically for this class. After the classroom instruction, we usually head out into the Arboretum’s collections for live demonstrations. It’s these discussions that will be presented as videos. These will be presented individually and will include time for a live discussion and questions.
