Food forests are designed, productive ecosystems modeled after natural forests, featuring diverse species in multiple layers that provide food with minimal input. This video details the seven layers of a food forest, from canopy to root yield and climbers, and explains how to strategically plant support species alongside productive ones to shelter, fertilize, and condition the soil. It also covers techniques like pollarding and using animals like ducks to accelerate establishment and maintenance, ultimately creating a self-sustaining, high-yielding system.
