- Description
-
The Botrytis Group of Brassica oleracea is most commonly called cauliflower. The genus name Brassica is Latin for cabbage. It is a cool-season vegetable that does not tolerate heat well, therefore, it is typically grown in the spring or fall. Sow seed in late spring for a summer harvest, then again in late summer for fall harvesting. It is grown for the edible stem, buds, and flowers. The unshowy flowers have a spicy flavor.
For best-growing results, keep the soil moist and plant in a loam-based soil that is rich in nitrogen. The use of compost is ideal for soil enrichment. Mulching around the plants will help protect the surface roots and retain moisture.
It is not a frost-tolerant plant. It should not be sown if there is any possibility of frost.
Plants are ready for harvesting when the heads are 6-8" across, firm and tight.
Cauliflower is now available in a variety of colors.
In the form of compact heads, these are a popular vegetable that can be served raw or boiled. Often they are accompanied by a white sauce.
They are also used in pickle production.
Insects, Diseases and Other Plant Problems: Insects that may affect its growth are cabbage worms, slugs, aphids, and caterpillars. Watch out for leaf spot and black rot.
The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common Cole crop diseases and other plant problems.
