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.

Gardening in Louisiana

Louisiana has a humid subtropical climate with very mild winters and long hot summers. Year-round cool-season growing is possible; the summer is the only limiting factor.
