Workshops

Do you love trees but can’t tell an Ash from a Walnut, a Birch from a Beech, or a Spruce from a Fir? Are you looking to connect more with the natural world around you? Join Shelley Hunt, U of Guelph course instructor and former Arboretum Director, for a virtual, interactive tree identification workshop. Over the course of 4 Zoom sessions, with hands-on challenges to complete in between, you will learn the basics of tree ID, with a focus on native Ontario species (and their look-alike non-native counterparts). You will learn about the important features to look for (e.g. leaf shape and arrangement, bark characteristics, fruits and cones), as well as the details that help us to distinguish between species in the same group (e.g. Ashes, Pines, Maples). You will practice your skills on trees that you can find in your local area, and get feedback on your ‘homework’. The fourth session will include a virtual tour of trees in The Arboretum's collections. 

Please Note: This course is only on-line. A separate in-person course is also available on June 19.
We also send recordings out after each session, so if you miss a session you can watch the recording. The recordings are avaialble for one month after the end of the workshop.

Fee: $50 (plus HST) per person.

What is a gall? If you’ve ever noticed a strange bump, ball, or swelling on a leaf or stem, you’ve likely spotted one—but what caused it? Galls are abnormal plant growths triggered by a diverse range of organisms, including insects, mites, and fungi. Far from being mere deformities, these structures serve as protective homes and food sources for the creatures that create them. They come in an astonishing variety of shapes, sizes, and colors—each with its own unique natural history.

Join us for a workshop on the Galls of Southern Ontario, where we’ll explore their incredible diversity, how they form, the organisms behind them, and so much more. This hybrid workshop will begin indoors with an introduction to gall biology, followed by an outdoor exploration in The Arboretum, where we’ll search for galls in the field. With well over 100 types of galls found here, there’s an incredible amount to discover!.

*Maximum 18 adults.

Fee: $94 (plus HST) per person if you register by the early bird deadline of August 19, 2025. After August 19 the fee is $104 plus HST.
