Tips & Best Practices
- Cauliflower is more temperamental than broccoli — it needs consistently cool temps (60–70°F).
- Start indoors 6 weeks before the last frost; transplant 2 weeks before.
- Blanch white varieties by tying leaves over the developing head when it is 2–3 inches.
- Fall crops are often more successful because temperatures trend cooler during head formation.
