“We have pressing issues if we and our children are to survive - food, drinking water, climate, soil. Each of us will have to recognize that it is up to us as individuals to be the wind and not seek a weathervane. The winds bring change.” 

Johanne Daoust, Owner


A Study in Sustainability

This compact 430 sq ft vegetable garden on the roof of a residential home consists of six raised cedar beds, vertical trellises for climbing fruit and vegetables like cantaloupe and butternut squash and over 50 planters of various sizes, shapes and material.

A versatile aluminum framing system encompasses the raised beds and acts as a base for the trellises. It also enables the beds to be used as season extenders by a variety of covering such as greenhouse plastic, shade cloth and wire mesh. The various covers protect the plants at critical stages of growth from critters and the environment i.e. strong winds, excessive rainfall, blistering sunshine, birds, squirrels and raccoons.

The raised beds and planters feature a sub-irrigation system that capitalizes on capillary action with no loss of water or fertilizer run-off. The system provides the plants with consistent water and oxygen at the root level and greatly contributes to their optimal growth in a challenging roof top environment.
