The Oakville Horticultural Society is excited to present All About Tea by Matthew Donovan on October 5th (note the date is one week earlier than we usually meet!)

Matthew's presentation will give an overview of the entire world of tea. He'll begin by explaining the botany of the Camellia sinensis plant, where all true tea originates, before reviewing the
ancient history of the tea beverage up to the present day. He will also dive into tea processing, and how we have arrived at the six families of tea that are known across the world. Finally, he'll describe the unique health benefits of tea, and the terroir quality which gives tea a 'taste of place'. To conclude, he'll be giving out
samples of two unique teas while explaining their origin and all the factors that contribute to their wonderful and distinct flavours.

Join us Oct 5th at 89 Dunn Street in Oakville. Doors open at 6:30pm, presentation begins at 7:30pm. Guests are always welcome!

We're back!

Join us Monday September 14th at 7:30pm, 89 Dunn St in Oakville (basement of Knox Presbyterian Church) with special guest Dr. Janet Padiak.

"Good Bug, Bad Bug: Gardening with IPM"

When home gardeners use Integrated Pest Management (IPM), they protect pollinators and beneficial insects, support diversity, and have healthier, more productive gardens. This presentation reviews the steps of IPM with reference to specific pests and key strategies that work. The goal is to utilize non-chemical deterrents first, reaching for the spray only as a last resort, therefore reducing residual pesticides in the plants, soil and run-off water.

Doors open at 6:30pm, talk starts at 7:30pm.
Guests always welcome!

🌿🎨 Art in the Garden 🎨🌿

We recently hosted a beautiful morning of art and conversation in our Teaching Garden! It was a wonderful opportunity to slow down, get creative, and appreciate the beauty of nature all around us.

A heartfelt thank you to Natalie for leading the art session and
inspiring us to look more closely at the colours, shapes, textures,
and little details that make our gardens so special. 🌸🖌️
We are so grateful that she generously shared her skills and passion with us! 💚

We made new friends, shared ideas, enjoyed a lovely morning in nature, and left feeling inspired by the creativity and talent within our community.

Thank you to everyone who joined us — we hope to see you again in the garden soon!
