Soil needs to be very rich in organic matter; mix aged maure and/or compost inot the bed.
Cauliflower also needs extra nutrients. Apply 5-10-10 fertlizer. Fertile soil holds in moisture to prevent heads from “buttoning.”
It is best to start cauliflower from small nursery plants versus sowing seeds.
If you seed, start 4 to 5 weeks before the last spring frost date. Sow in rows 3 to 6 inches apart and up to ½ of an inch deep. Water consistently during germination and growth.
Transplant seedlings (or small nursery plants) 2 to 4 weeks before the last spring frost date, no sooner and not much later.
Set plants 18 to 24 inches apart with 30 inches between rows.
In early spring, be ready to protect plants from frost by covering them with old milk jugs, if necessary. Extreme cold can halt growth and/or form buttons.
Plant a fall crop 6 to 8 weeks before the first fall frost date but after daytime temperatures are regularly below 75°F. Shade plants from heat, if necessary.
