Before Planting

Cauliflower needs full sun, fertile soil, reliable drainage, and a bed where brassicas have not grown recently. Incorporate compost and adjust pH or nutrients from a soil test, liming only when indicated. Firm the bed and harden transplants before setting them out.

Planting

Cauliflower may be direct-sown in cool weather or started indoors 4–6 weeks before transplanting. Maintain about 70–75°F until germination, then give seedlings bright light and cooler conditions. Harden transplants gradually and set them out before summer heat for spring crops, or sow in midsummer for fall harvest. Thin direct-sown seedlings after true leaves develop.

Watering

Keep cauliflower evenly watered through active growth and head or stem development. Supply deep irrigation when rainfall is insufficient, avoiding drought stress, standing water, and frequent wet foliage.

Fertilizer

Support cauliflower growth with balanced nutrition and adequate nitrogen. Side-dress after establishment when needed, but avoid overapplication that encourages soft growth and delays maturity.

Harvesting

Cut cauliflower when the head is firm, compact, and fully sized but before curds loosen or discolor. Leave several wrapper leaves attached to protect the head during handling.

Tips

Mulch cauliflower to moderate soil temperature and reduce weeds. Use crop rotation and physical insect barriers early, removing covers when pollination is required or plants become crowded.

Pests & Diseases

Cauliflower is especially susceptible to black rot and also develops clubroot, downy mildew, and Alternaria. Remove plants showing V-shaped leaf lesions or foul soft rot near the curd. Plant clean transplants, keep brassica debris out of compost piles that do not heat thoroughly, and correct acidic clubroot-prone soil from test results.

Cauliflower may attract cabbageworms, loopers, aphids, flea beetles, and slugs. Inspect frequently, use physical barriers early, and choose targeted biological controls instead of broad-spectrum insecticides.
