Hidden Harvest Workshop

Edible Fruit and Nut Trees of Ottawa  

There are edible food trees hiding in plain sight all around Ottawa! Hidden Harvest Ottawa organizes urban tree harvests to rescue food that would otherwise go to waste, and to donate the food where it's most needed. Join us to learn more about the edibles at your doorstep, and what you can do to ensure local fruits and nuts nourish people instead of the compost bin. Weather permitting, we will take a short stroll around Lansdowne and the surrounding area to identify edible trees.
