Growing
A tight, creamy head requires attention to soil chemistry and moisture. When preparing your garden bed, aim for a slightly acidic soil with a pH between 6.0 and 7.0. Because cauliflower is a heavy feeder that relies on large food reserves, make sure the soil is rich in organic matter. Since this is a cool-season annual, you can start seeds indoors before transplanting them into the garden once the soil has warmed.
As the plant develops its single upright stem, watch the developing curd. To prevent the head from turning bitter or developing purple tints from sun exposure, you may need to blanch the plant by gently folding the outer leaves inward to cover the center. This protects the developing inflorescence from direct light. Watch for common brassica pests that target the tender leaves and heads, and keep the soil moist but never waterlogged to prevent root issues.
Harvest when the head is firm and compact, but before the individual flower buds begin to loosen or spread. Unlike some vegetables, cauliflower does not continue to ripen once it is picked, so harvest it when it reaches your preferred size. For long-term use, you can store unwashed heads in the fridge, or blanch the florets before freezing them.
