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 of 45 cents per kilometre is also payable to the speaker.

Caring for your lawn and landscaping with lawn alternatives
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
Holistic garden fertility management – working with nature: Best practices for taking care of your garden – holistically and organically. It all starts with the soil. You will be taken on a journey through the Soil Food Web which is the basis of a healthy, productive garden. Astrid Muschalla
Ornamental grasses. Speaker: Pat Haslett
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
Putting your garden to bed for the winter: Fall clean-up and winterproofing your garden. Speaker: Nancy Louwman
Wipe out weeds, the organic way. Speaker: Astrid Muschalla
Good weed, bad weed: Learn to identify common weeds, understand what they’re telling you about your soil, decide how to control them and why you might even want to love some of them just the way they are. Speaker: Joyce Hostyn
Nurturing the soil
Soil health approach: Soil secrets are uncovered. Learn how bacteria and fungi, the soil’s structural engineers, create good soil health which in turn grows healthier plants, increase yields, reduces fertilizer needs, prevents leaching and erosion, holds more water and saves money. Speaker: Astrid Muschalla
Become a worm wrangler through vermi composting: Worm castings (poop) contain 8 times as many microbes as their feeed, no disease pathogens, 5 times more nitrogen, 7 times more phosphorus and 11 times more potassium than ordinary soil so a little goes a long way. This is the a-z of how to farm worms successfully. It’s easy and fun too! Speaker: Astrid Muschalla
Indoor bokashi composting: An easy DIY method for creating fertility for your garden. Bokashi composting starts the process of decomposing things that would otherwise be harmful in an outdoor aerobic compost pile such as meats, dairy and fats. Another benefit is that less carbon is converted to carbon dioxide and so more available carbon is recycled into the ecosystem with a greater chance of converting into humus. The nutrients are also not as water soluble and therefore less prone to leaching away with watering – and so more for your plants! Speaker: Astrid Muschalla
Foundation of healthy gardens: wild soil inhabitants: A healthy garden starts from the ground up. Introducing the Soil Food Web – an interdependent web of life. The plant you see above ground is actually in a complex symbiosis with soil microbes in the root zone. If you don’t know what organisms are present in your soil and on your plants, much of your garden management is being left to chance. This talk is about ways to keep your soil healthy which in turn grows healthier plants. Speaker: Astrid Muschalla
Making compost tea and other brews: Compost tea and effective microorganism brews are a holistic approach to garden health. Prevention is the best cure when it comes to plant health. Speaker: Astrid Muschalla
How to build a hugelkultur bed: Learn to make garden beds from old logs, twigs, and garden waste. Hugelkultur beds build soil fertility, retain moisture, improve drainage, sequester carbon in the soil, maximize growing space and increase soil temperature just enough to boost plant growth. Speaker: Joyce Hostyn
Designing your garden

Rainscapes are about water in all its forms – still and moving, above and below ground – and the rich design possibilities rain offers. Create a simple rain garden or turn your whole landscape into a rainscape that captures, stores and conserves water and creates a beautiful, wildlife friendly garden. Speaker: Joyce Hostyn
Hardy and tender bulbs: Learn how to distinguish the difference between hardy and tender bulbs with numerous examples of both.

Speakers: Joyce Hostyn, Astrid Muschalla
Increasing biodiversity and attracting wildlife to your garden
Designing with native plants: Astrid is amongst a growing number of garden designers championing the naturalist approach to garden design. She says “work with nature, not against; move towards a place that allows both nature and human habitation.” A two-time Evergreen nominee for outstanding contributions to urban stewardship in Ontario, a volunteer with stewardship programs which encourages the use of native plants, Astrid also volunteers as a Master Gardener for Rideau 1000 Islands. “Seeing the way plants grow around the world convinced me that the natural balance and beauty there can be reinterpreted to create gardens which are both calming and exciting. There is an inherent grace in the wild which I believe should be encouraged into our gardens. Speaker: Astrid Muschalla

Eradicating Invasive plants: What’s invading next? Alien invasives are proving to be aggressive monocultures destroying native habitats. As a result we are loosing native species which changes the land use, water quality and does not support desireable wildlife and plants. You will learn how to identify, remove and replace alien invasive plants with desireable native species to keep our natural areas functioning as healthy ecosystems. Speaker: Astrid Muschalla

Cultivating ecology, 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
Wabi Sabi: seeing the beauty of a naturally imperfect garden: Increase beauty and enchantment in your garden by embracing the ancient Japanese practice of wabi sabi. Loosely translated wabi is simplicity (elegant or rustic) and sabi means the beauty of age, wear or seasons. Speaker: Joyce Hostyn
