Cauliflower is a cool-weather crop and is not heat-tolerant. It is part of the cruciferous/brassica vegetable family, which is considered to have many health benefits as well as cancer-fighting nutrients.
Faster-maturing varieties can be started indoors 4-6 weeks before the last frosts for a spring planting. Longer-maturing varieties should be started 8-10 weeks before your first frost for an autumn harvest. A dusting of frost enhances the flavour.
Although a hungry crop, beware of using fresh manure as it can influence the colouring and flavour adversely.
