Cauliflower thrives in well-drained, fertile soil with a slightly acidic pH (6.0-6.5). Here’s how to prepare your soil:
1. Test the Soil: Use a soil test kit to determine the pH and nutrient levels.
2. Amend the Soil: If the soil is too acidic, add lime. If it’s too alkaline, add sulfur.
3. Incorporate Organic Matter: Add compost or well-rotted manure to improve drainage and fertility.
4. Till the Soil: Work the soil to a depth of 12 inches to loosen it and create a good seedbed.
