Register: Online here (required), program fee is offered on a sliding scale ($0-$10)

The growing season is short in New England, but techniques ranging from simple to ambitious can help extend it by weeks, months or even year-round. That could mean being able to grow crops you haven’t been able to before, or simply getting to grow and harvest during months previously out of reach. Season extension techniques often make for healthier and more productive plants, too! This webinar will share the possibilities of season extension, different strategies ranging from strategic use of mulches and row covers to small high tunnels, and in-depth guidance on how to build and implement these systems in your gardens.

We all know that from an acorn a mighty oak can grow but did you know there was another way to start a tree? Creating new plants from cuttings is an inexpensive and fun gardening project that can take place even in the winter months and is often not as challenging as you would suspect. Certain trees and shrubs are best propagated from cuttings taken in late winter or early spring while plants are still dormant. Dr. Bryan Peterson will share suggestions on which plants to propagate this time of year, essential tools and supplies, and best practices for success.
