How To Grow Cauliflower Q&A
Q: What are the ideal growing conditions for cauliflower?
A: Cauliflower grows best in cool weather with temperatures between 60–70°F. It prefers a garden bed with fertile, well-drained soil, a pH of 6.0–7.0, and consistent moisture. Because cauliflower is more sensitive than other vegetable plants, it struggles in the heat of summer and thrives in spring and fall.
Q: Is cauliflower difficult to grow compared to other vegetables?
A: Yes, cauliflower is considered one of the more difficult to grow garden vegetables. Unlike broccoli and cauliflower’s other Brassica relatives, cauliflower is more sensitive to temperature swings, soil fertility, and watering. With careful timing and steady care, though, you can get excellent results.
Q: When should I start cauliflower seeds?
A: For a spring harvest, start cauliflower seeds indoors 4–6 weeks before the last expected frost. For a fall harvest, start cauliflower 6–8 weeks before the first fall frost date. Cauliflower is best started indoors as seedlings rather than direct sowing, since it needs steady growth without setbacks.
Q: How big should heads of cauliflower be before harvest?
A: Heads of cauliflower, also called cauliflower curds, are ready to harvest when they grow to 6 to 8 inches in diameter. Some cultivars may reach 8 inches in diameter or more, but it’s best not to wait too long or the curds will loosen and lose flavor.
Q: How many days does it take cauliflower to grow?
A: Depending on the cauliflower cultivars you choose, the time to grow from seed to harvest is usually 55–100 days. Spring-planted cauliflower matures faster, while fall crops may take longer but often produce tighter, better-quality heads.
