2024 Earth Day Celebration Video Link & Links to Important information 

Below is the link to the Earth Day presentation put on by our OHA as well as list of resources shared by Claudette Sims after the OHA Earth Day video.  

Regards, Doreen Coyne
President, Richmond Hill Garden & Horticultural Society

From the OHA:

We are excited to share the link to our Earth Day Celebration video which took place on April 19, 2024. Find it at this link:

The OHA was very excited to have Claudette Sims speak at our Earth Day Celebration where she discussed "A Gardening Conundrum: Why are invasive plants sold in nurseries?  Invasive plants are a threat to biodiversity, human health and our economy. They threaten native plants, insects, animals and our forests. So why are they still sold in nurseries? This talk will answer that question and suggest actions that we can all take to safeguard biodiversity.

We also had the OHA's Conservation & Environmental Committee share "What's New for Societies/Clubs" and who provided an excellent presentation on  "Harmful Foreign Species Have Invaded Ontario - Learn how you can help stop the spread"  As discussed in the video, we have attached the plant sale information documents, flower show guidelines and invasive species document.

Special thanks goes out to Claudette Sims, Sandra Rammelaere, Joyce Schlegel, Debi Foster, Karen Redmond, Kathy Bouma and OHA President, Sharlene Desjardins for making it a very successful evening!

We have some excellent resources to share with everyone, care of Claudette Sims:
