Spring and Summer Vegetable Gardens

There are a lot of planting options for spring and summer vegetable gardens. When choosing what and when to plant, consider their days to maturity requirements to determine if your selections will be ready before the end of the school year, during the summer or for next year’s back to school.

Spring vegetables are cold hardy and can tolerate the most low night temperatures of March. You can get a jump on your garden by starting some of your seeds indoors. Don’t rush to plant your summer vegetables before May. The cold can kill them or stunt their future growth. See our spring and summer vegetable favorites below.


February / March:

  • Harvest long maturing fall planted vegetables.
  • Leave some open pollinated plants in place to develop seeds for collection.


  • Plant from spring favorites list.
  • Avoid long maturing warm season vegetables that will be available in nurseries but will not mature until summer break (ex. tomatoes).


  • Harvest spring vegetables.
  • Add compost and plant summer crop from favorites list (if summer gardener & irrigation is available).
  • Plant pumpkins in May and corn and tomatoes in June for a back to school harvest.
