Growing Tips for Cauliflower

- Keep soil evenly moist — drought stress causes small, bitter 'buttoning' heads instead of full curds.
- Plant fall crops in mid-July to mid-August for October harvest; fall cauliflower is usually larger and sweeter than spring.
- Use floating row covers at transplanting to block cabbage white butterflies from laying eggs.
