Fall Vegetable Gardens

artichoke
Most schools are not ready to plant their fall vegetable gardens until mid-September, a month or two past the ideal time to start long days to maturity vegetables like broccoli, carrots and even some lettuce and beet varieties.  These vegetables do most of their growing in the warm months of July-October. As the temperatures cool, growth slows and the cool air acts as a refrigerator to preserve the plant.

When you start your fall vegetable garden in September, we recommend choosing fast days to maturity vegetables and varieties.

September:

  • Harvest summer vegetables except corn and pumpkins (save corn & pumpkins for a Halloween party).
  • Provide seed saving lessons and save seed for next year.
  • Amend soil with compost.
  • Plant fall favorites.

October:

  • Halloween Harvest – corn (make popcorn or cornbread depending on variety) & pumpkins.
  • Chard, Mizuna and Tatsoi may have some harvestable leaves.
  • Amend harvested bed and plant from fall planting list including edible fava beans.

November:

  • Thanksgiving Harvest – Harvest fast maturing fall planted vegetables, leave some open pollinated plants in place to develop seeds for collection.
