I am currently doing free osu intro to permaculture course and perennials are much preferred over annuals in permaculture as there's less soil erosion and less overhead and less work!
- Gibbon1 7y agoI read a page on some agriculture professors home page. The plants were rely on for food are mostly annuals because the short life span allowed for faster selective breeding. That comes at a very high cost. There is a litany of problems with annuals. The need to constantly replant every year Leading to soil erosion. Need for herbicides to control weeds. Continual harvesting results in depleted soil. Requiring fertilizer. Short roots means low drought tolerance Need for irrigation. irrigation --> salinization Perennials are more drought tolerant, need less water and fertilizer because of their deeper root systems.
