Growing Guide

When to Grow

This variety can be planted in early spring for a summer harvest or late summer for a fall harvest. Start seeds indoors 6-8 weeks before the last frost date and transplant out when the plants are 4-6 weeks old with 4-5 true leaves, around 2 weeks before the last frost. For a fall harvest, count back about 16-20 weeks from your average first fall frost: sow indoors in early to midsummer and transplant out about 10-12 weeks before that first frost, so the heads get the full 70-80 days they need. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Start seeds indoors 1/4 to 1/2 inch deep in seed trays. After 4-5 weeks, transplant seedlings outdoors, spacing them 18-20 inches apart in rows that are 24-36 inches apart. Ensure the planting site receives full sun and has well-draining, fertile soil.

How to Grow

De Jesi cauliflower requires regular watering to keep the soil moist but not waterlogged. Mulching around the plants helps retain moisture and regulate soil temperature. Fertilize every 3-4 weeks with a balanced fertilizer. To maintain the heads' white color, blanch them by covering them with leaves when they reach 2-3 inches in diameter.

How to Save Seeds

  • For a seed saving crop, isolate cauliflower from other brassicas (such as broccoli and kale) by one mile to avoid cross pollination.
  • Select your best plants to keep for seed and leave them to flower.
  • In short-season areas with harsh winters, the plants can be mulched and left in the ground with a row cover, and in the second season the plant will send up flower stalks from the head. As they mature, they will become seed pods.
  • Once the plant has died back and the seed stalks/pods are brown and dry, pull the entire plant and hang it for up to two weeks in a dry, well-ventilated area.
  • Break open the seed pods with your hands or a rolling pin over a container such as a bowl or plate, and separate and extract the seeds.
  • Properly stored (keep them cool and dry!), the seeds of cauliflower and other brassicas will be viable for up to five years.
