What Is Allelopathy?

When a plant produces one or more biochemicals that influence the germination, growth, survival, and reproduction of other plants. A common Allelopathic plant in North America is Black Walnut.

Allelopathy isn’t always negative as the biochemicals produced can sometimes work to benefit an ecosystem by inhibiting the growth of invasive species. A proper permaculture design can implement Allelopathic plants into the whole system design for this benefit and food production.
