Broccoli

Quick Garden Tips

  • Broccoli is a member of the mustard (or cole) family along with Brussels sprouts, cabbage, cauliflower, kale and radishes.
  • Start seeds indoors about 6 weeks before planting time or transplant a start into your garden. Plant 12 to 24 inches apart.
  • Water to keep soil evenly moist.
  • Add a balanced fertilizer every 3 to 4 weeks after the plant is about 4 inches tall. Follow fertilizer package directions.
  • Hot temperatures (above 80 degrees F) cause broccoli plants to send up flowering stalks. This is known as bolting. Once broccoli bolts, it can taste bitter and may not be good for eating.

Season and Location

  • Plant in fertile, well-drained soil in full sun.
  • Broccoli prefers cool weather, so plan for a harvest in spring or fall.

Container Gardening

  • Choose small, compact varieties such as Small Miracle or Green Comet.
  • Use at least a 5-gallon container with holes in the bottom for drainage.

Key Pests and Diseases

  • Aphids: hose off with water.
  • Cabbage worms: remove by hand.
  • Use plant covers early in the season to reduce pests.
  • To help reduce disease, do not plant cole family vegetables in the same area more than once every 3 or 4 years.
