When to plant:

  • Broccoli can be planted in both the Spring and Fall. The seeds can germinate with temperatures as low as 40 degrees F.

How to plant:

  • Broccoli needs full sun and moist soil.
  • Slightly acidic soil is prefered - for soil testing, contact your local Agricultural Extension office.
  • Plant the seeds ½ inches deep in fertile soil.
  • If planting in rows, plant 12-24 inches apart with rows 36 inches apart.
  • Make sure to keep your broccoli plants watered, but take care to not get the developing broccoli heads wet while watering.
  • For Spring planting: sow seeds indoors 2-3 weeks before the last frost.
  • For Fall planting: sow seeds 85-100 days before the average Fall frost, during mid- to late-summer.

When to harvest:

  • Harvest your broccoli when you see that the buds of the head are firm.
  • Cut the stalk of the main head at a slant, and smaller side shoots will grow up from where you’ve cut.

**If you live in a warmer climate, broccoli does best with a Fall planting. If you fear that your soil will be too hot, a layer of mulch will help ensure cooler soil temperatures. Make sure to harvest your broccoli before the yellow flower petals start to show - those parts have a mealy texture.
