Are you interested in inviting a Master Gardener to speak at your event? We can provide in-person or virtual presentations. We have some talks ready to go – review our Presentation Topics below. Other topics can be requested. Talks can be tweaked for length and content depending on the expectations of the audience.

Please note: Master Gardeners of Ottawa-Carleton is a group of volunteers who provide unbiased horticultural advice and expertise to the home gardener. We provide this free advice to the public by running advice booths and clinics at various venues in the Ottawa-Carleton region, such as markets, local fairs, and other events as requested. We are also prepared to provide talks on a variety of garden-related topics to groups. We usually receive an honorarium for such talks. This helps defray the costs of our continuing education activities and administrative expenses.
