Join us April 13th for a special presentation by Ramona Christiansen How Trees Communicate: The Fascinating World of Mycorrhizal Connections.

We tend to think of trees in a forest as silent sentinels that compete with one another for water light and nutrients. But what if these assumptions are all wrong? Science has discovered that trees are actually social creatures that communicate with one another. Trees are linked to neighbouring trees by an underground network of fungi that resembles the neural networks in the brain. And, instead of simply competing for resources, they share them in times of stress. This is the fascinating underground world of mycorrhizae; a network of fungi that are extraordinarily important to trees and our climate. All trees and all plants in all of our forests around the world are dependent on the symbiotic relationship between the mycorrhizal fungi and the trees and plants. Learn what you, the backyard gardener can do, to help your trees flourish while protecting these fungi.

Oakville Horticultural Society April 13, Knox Presbyterian Church (we meet in the basement) 89 Dunn Street Oakville. Doors open 6:30pm, activities start 7:30pm. Guests are always welcome!
