Pruning Program

GJG is thrilled to announce its Pruning Training Program taught by professional aesthetic pruners.

The pruning program is designed for gardeners and landscape professionals interested in pruning for the health of a plant and aesthetics of the plant and landscape, while advancing your pruning and plant knowledge and skills.
Each course focuses on different aspects of pruning in regards to different plant material. See below. Check back often. New courses are added all the time.

Spring Courses

We’re adding a scientific element to GJG’s pruning program.

Pruning Broadleaf Evergreen Shrubs: Saturday, June 24th, 12pm-2pm: $45

Where do you even start when you look at your evergreen shrubs? Learn ways to gracefully bring your shrubs back into order. Learn when to prune and how to prune. Not all shrubs react the same to pruning. This workshop is in person at the Gresham Japanese Garden.

Bring your pruners just in case Francheska lets you work on a shrub.

Soil – What it is and How it Works, Zoom, June 19th, 6-7:30pm

You will learn more than you ever thought possible about soil, including why you are alive, what nutrients are, and how soil stores water and nutrients, all fundamental information important to your landscape.
