How to use frost dates

  • Cool-season crops such as peas, lettuce, spinach and onions can go in several weeks before your last spring frost.
  • Warm-season crops such as tomatoes, peppers, squash and beans wait until after it, when the soil has warmed.
  • Fall crops are timed back from your first fall frost, and garlic and tulips are planted around it.
  • Frost dates are averages. Check the forecast before setting out tender plants.
