Growing Broccoli

Broccoli prefers cool weather to grow. Plant in the early spring for summer or early fall harvest and early summer for late fall harvesting. Small heads called side shoots will form on the stem after the large head is harvested. These can be cut and used to extend your harvest. These vegetables are best transplanted as they get more growth before the heat of summer.
