When to Plant Cauliflower Seeds
Cauliflower requires a specific set of temperatures and soil qualities. Plant seeds inside 4-5 weeks before you transplant. Transplant your seeds 2-4 weeks before the last frost in the Spring or 6-8 weeks before the last Fall frost if doing a Fall planting.
Where to Plant Cauliflower Seeds
Before planting, check to make sure that your soil pH is between 6.5 and 6.8. Find area that has well-draining soil and in full sunlight.
How to Plant Cauliflower Seeds
Plant your seeds 18 to 24 inches apart with room to walk between the plants if planting in rows.
How to Harvest Cauliflower
Cut the heads off with a large knife when the heads are firm and compact. *When you see the white head’s diameter is 2-3 inches, blanch the leaves to get the whitest cauliflower. Cauliflower needs at least 6 hours of full sun per day in order to perform its best.
