Community gardens make growing space available to people who don't have a yard. Several directories of Toronto community gardens are listed below.
Find a garden in your neighborhood and contact the community garden manager to ask for a growing plot. It is often a first come/first serve basis and the fees vary from free to $50.

Seed libraries create collections for growers to "borrow" seeds for an initial harvest. After the harvest, the grower is encouraged to collect seeds from the plant or fruit and "deposit" the seeds back in the seed library. Seed libraries might specify organic, non-GMO, or heritage seeds. These resources may also provide learning events and instructions on growing.
