Broccoli is harvested when the tiny buds are full-sized, but before they begin to open. “Sprouting types” need a winter’s chill before they will yield reliably; for spring planting, choose Waltham 29. Rapini is planted spring or fall; entire plants are harvested when the first flower buds begin to open.
