Soil Preparation:

Planting:

  • Broccoli 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.  
  • Fall planting should occur 50-75 days before the anticipated maturity date. The maturity date can be several weeks after the first fall frost.

 

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

 

Fertilization: Apply a nitrogen-based fertilizer 4 weeks after transplanting or thinning. Reapply when the heads are the size of a quarter. Apply again after harvesting the head to encourage side shoots. For more information on fertilizing, click here

Harvest: Cut broccoli when the head is fully developed, but before the flowers open enough to show yellow.
