- Soil requirements: Cauliflower prefers well-drained, fertile soil with a pH level between 6.0 and 7.0. The soil should be rich in organic matter and have good moisture retention.
- Sunlight needs: Cauliflower requires full sun, which means it needs at least 6 hours of direct sunlight per day.
- Watering requirements: Cauliflower needs consistent moisture. Water the plants regularly, ensuring the soil remains evenly moist but not waterlogged. Mulching can help retain soil moisture.
- Planting season: The best time to plant cauliflower seeds is in early spring or late summer for a fall harvest. In cooler climates, seeds can be started indoors 4-6 weeks before the last frost date.
- Depth and spacing: Plant cauliflower seeds at a depth of 1/2 inch. Space the seeds 18-24 inches apart in rows that are 24-36 inches apart to allow for adequate growth and air circulation.
- Germination time: Cauliflower seeds typically germinate within 7-14 days under optimal conditions.
- Maturity time: Cauliflower plants usually reach maturity and are ready for harvest in 55-100 days, depending on the variety.
- Harvesting time: The best time to harvest cauliflower is in the morning when the temperatures are cooler. This helps maintain the crispness and quality of the heads.
- Harvesting tips: To harvest, use a sharp knife to cut the head from the main stem, leaving a few leaves around the head to protect it. Store harvested cauliflower in a cool, dry place or refrigerate it to maintain freshness. Avoid letting the heads become overripe, as they can become tough and lose flavor.
