When to Plant Cauliflower in Virginia

The diva of the brassica family. More temperamental than broccoli but worth the extra attention.

The Short Answer

Virginia's moderate fall provides reasonable cauliflower conditions in the Piedmont and Tidewater, where the gradual cooling trend from September through November supports head formation. Mountain Virginia's consistent cool temperatures are the best in the state for this temperamental crop.

Common Challenges in Virginia

Temperature spikes during heading. Cabbage worms. Harlequin bugs. Clubroot in acidic mountain soils.

Growing Tips

Blanch white varieties by tying outer leaves over the head when it reaches 2 inches. Temperature swings cause buttoning.
