When to Plant

Cauliflower is a cool-season crop that does not tolerate extreme heat. Rough heads or leaves in the head are usually from heat stress. 

Other Considerations

Keep beds evenly moist and/or use shade cloth to maintain quality during heat waves. To ensure completely purple heads, tie the inner leaves around the head when it starts to form, or break over some inside leaves to shade the head.


Harvest when heads are tight and dense. Over-mature florets begin to separate and appear ricey. 


Store at 36°F and 95% relative humidity.

Pest Info

Aphids, Cabbage Worms, Flea Beetles, and Symphylans can all target cauliflower. Observe plants regularly for signs of pest damage.
