Why every two years?

This unique Permaculture workshop and seminar is offered biannually (every two years) in southern Ontario so that participants can gain an appreciation of how an orchard polyculture develops over time.

Different species grow at different rates and start producing in different years. Additional yearly plantings bring diversity and variety and hence ecosystem services that build resilience in the production matrix. Mortality, dieback and other stresses are observed and explained. New soil improvement and pest management strategies are introduced over time and assessed. Cultural forms with intangible values take on greater meaning over time.

It is important to gain an appreciation of both spatial and temporal development of man-aged edible ecosystems over time; they mature and improve! The Aisling Keep Workshop offers an opportunity to observe and experience this first hand.
