Leafy crop that needs steady nitrogen. Inconsistent feeding causes poor head formation.

Succession Planting

Sow every 4 weeks

Sow a spring crop and a late-summer crop. Cabbage takes too long for rapid succession but two crops a season — one for summer, one for autumn/winter — is very achievable.
