Frequently Asked Questions

Why is my Cauliflower head discolored or 'riced'?

Riciness and discoloration happen when the crop lacks consistent moisture and cooler temperatures — keep soil consistently moist at 1.5–2 inches per week and grow in the cooler 60–70°F range for dense, quality heads.

Is Cauliflower harder to grow than Broccoli?

Yes, somewhat — Cauliflower is described as moderately challenging, needing more precise moisture, nutrition, and cooler temperatures than Broccoli to develop quality heads without riciness.
