Cauliflower (Brassica oleracea) is a cool-season brassica that thrives in zones 2-10, producing dense, edible curds in just 40-49 days. This hybrid grows 12-18 inches tall and prefers full sun with moderate water and slightly acidic to neutral soil (pH 6.5-7.5). Its compact size and relatively quick maturation make it accessible to gardeners across most of North America, though it performs best when planted in early spring or fall to avoid summer heat.

Cauliflower demands cool weather to produce its best curds, which means savvy gardeners time their plantings for spring and fall crops when temperatures naturally favor growth. The frost-hardy nature of this annual means early and late season sowings won't be derailed by light freezes. With 18 inches of spacing and mature heights around 12-18 inches, it fits neatly into organized garden beds or container growing, making it practical for gardeners with limited space.
Cauliflower is harvested for its edible curds, which are the dense, immature flower clusters that form at the plant's center. These curds can be steamed, roasted, pureed into soups, pickled, or eaten raw with dips.

Start seeds indoors 4-6 weeks before your last spring frost or 8-10 weeks before your first fall frost. Maintain soil temperature between 65-75°F for reliable germination. Transplant seedlings outdoors once they develop true leaves and soil has warmed sufficiently.
Transplant hardened-off seedlings outdoors when soil temperatures reach at least 60°F. Space plants 18 inches apart with 24 inches between rows. In spring, wait until soil is workable but frost danger has passed. For fall crops, transplant in mid to late summer so plants mature before first frost.
Direct sow seeds outdoors 4-6 weeks before your target harvest date in spring or fall. Sow seeds into moist soil and thin seedlings to 18-inch spacing once they develop true leaves.
Harvest cauliflower curds when they reach full size but before they begin to separate or flower. The curds should be dense, compact, and tightly packed. Cut the main head at the base with a sharp knife, leaving the plant in the ground if you wish to harvest smaller side shoots that may develop. In most growing conditions, harvest occurs 40-49 days after transplanting, though timing varies with temperature and planting date.
