About Cauliflower

Cauliflower is one of the most rewarding cool-season brassicas — and one of the trickiest. It forms a dense white head that needs steady cool weather and consistent moisture.

Start indoors 6 weeks before last frost; transplant 2-3 weeks before last frost. Blanch heads by tying leaves over them once they're 2-3 inches across. Harvest before curds loosen.
