  • Brussels sprouts can be grown from seed or transplants.
  • Seeds should be planted ¼-1 inch apart, in rows 1-3 feet apart. Thin plants to 12 inches apart when they have 3-4 true leaves.
  • Transplants may be planted 2-3 weeks before the last frost-free date. Start seeds indoors 5-6 weeks before planting. For more information on frost dates, click here
  • Planting for fall harvest should occur in June and July.

Irrigation: Brussels sprouts prefer deep, infrequent watering, about 1-2 inches per week. For more information on watering, click here.   

Fertilization: Apply a nitrogen-based fertilizer at 4 and 8 weeks after transplanting and/or thinning. Avoid fertilization during sprout formation as this may cause loose, soft sprouts and splitting. For more information on fertilizing, click here.   

Harvest: Brussels sprouts should be harvested when they reach 1 inch in diameter.
