Do you need a speaker or workshop facilitator for your club or organization?
Our speakers educate on ecological gardening practices, share their deep horticultural knowledge and inspire with possibilities for what your yard could become.
We’re happy to tailor our presentation topics or offer custom talks with enough advance notice. If you don’t see the topic you’re interested in, let us know – we’re always looking for new ideas!
While our speakers don’t charge for their services, we do ask for an honorarium payable to Rideau Thousand Islands Master Gardeners. The honorarium supports our educational work. A mileage fee is also payable to the speaker.

Wildscaping: Landscaping with lawn alternatives
Wildscaping: a new approach to gardening in a changing climate: With climate change, our perspective on what a garden should be and what we like to grow in it has to change. Our weather is becoming more variable with wetter springs, drier summers, colder winters and more extreme storms. Learn how to adapt your gardening style for a changing climate, drawing inspiration from our local landscapes and indigenous flora to create naturalistic and sustainable gardens. Speaker: Joyce Hostyn
Organic lawn care: A healthy lawn is easier and cheaper than you think. Topics include how to support grass feeding needs without synthetic fertilizers, how to convert a neglected lawn back into a lush, healthy grass ecosystem and maintenance tips for preventative care. Speaker: Astrid Muschalla
Perfectly imperfect lawns (by design): Lawns are no longer just about grass monocultures. You can have a polyculture lawn that’s stunning and ecologically friendly. Less mowing. No watering. No fertilizing. Wildlife friendly. Embrace the imperfection of a flowering lawn! Speaker: Joyce Hostyn
Sedgscaping: Think of the sedge or carex family as an early-season grass that looks good all summer. Not only do carex look good, they’re durable, adaptable plants that enhance the health of an entire plant community. Speaker: Joyce Hostyn
Meadowscaping: convert your lawn into a meadowscape even bylaw officers will love: A meadowscape is a wildish garden designed using primarily native plants (though you can mix in a few companionable non-natives) leveraging the power of systems and managed ecologically. Speaker: Joyce Hostyn

There is an inherent grace in the wild which I believe should be encouraged into our gardens. Speaker: Astrid Muschalla

Cultivating beauty, magic and wonder
Indoor Plants for Beauty, Health & Wellness
Speaker: Doris Power
The life changing magic of gardening: When I first become a gardener, I grew plants. Specimens bursting with vibrant colours, oversize blooms and striking foliage. In becoming a master gardener, I’ve tossed the notion that gardening is about growing plants onto the compost heap. My journey of discovery into new ways of seeing, growing and loving has tumbled me into a new, more magical relationship with my garden and with the earth. One is which I strive to think like a plant, find belonging in the ecosystem that I call home and embrace beautiful mess. Speaker: Joyce Hostyn
