Key takeaways
- Rotate crops on a four-year cycle: legumes, brassicas, roots, then alliums and potatoes
- Rotation reduces clubroot and other soil-borne diseases by up to 80% over four years
- Legumes fix nitrogen in the soil, benefiting the brassicas that follow the next year
- A three-bed system works well for small gardens by combining alliums with roots
- Green manures sown between crops add nitrogen, suppress weeds, and improve soil structure
- Keep a simple plan or diary each year to track which family grew where
