Shaded: the span between the dates frost passes in 9 of 10 years and 1 of 10 years[2][3]. Green: planting windows from the CSU rules applied to the median last frost (GardenFacts calculation)[6]. Exact dates are in the tables below.

These frost dates are odds from NOAA records for 1991 to 2020, not a forecast. In 9 of 10 years the last spring frost comes after April 1, and in 1 of 10 years it comes after May 6[2]. In the fall, the median first frost is October 27, and in 1 of 10 years the first frost comes before October 11[3]. Any year can be earlier or later. The numbers come from the Staunton Wtp weather station near the city center[5].

  • Hard freeze (28°F): median last spring date April 3, median first fall date November 5[7].
  • Frost-free growing season: at least 167 days in 9 of 10 years, 191 days in half of years and 211 days in 1 of 10 years[4].

When to plant vegetables

Colorado State University Extension wrote its vegetable planting guide for Colorado, so these dates are simple arithmetic from its rules and not advice from CSU[6]. Hardy vegetables such as broccoli, lettuce, peas and spinach can go in as early as 2 to 4 weeks before the median last frost, which works out to March 18 to April 1[6]. Semi-hardy vegetables such as carrots and potatoes can go in as early as 2 weeks before it, which is April 1[9]. Tender vegetables such as snap beans and sweet corn are started from seed around April 15[10]. Very tender vegetables such as tomatoes and peppers typically wait 2 or more weeks after the median last frost, so the earliest start is April 29[11].

  • Hardy (broccoli, cabbage, kohlrabi, lettuce, onions, peas, radishes, spinach, turnips): as early as 2 to 4 weeks before the median last frost (April 15) is March 18 to April 1[6]
  • Semi-hardy (beets, carrots, cauliflower, parsnips, potatoes, Swiss chard): as early as 2 weeks before the median last frost (April 15) is April 1, up to the median date itself[9]
  • Tender (snap beans, sweet corn, cucumbers, summer squash): from seed around the median last frost date, April 15[10]
  • Very tender (cantaloupe, eggplant, peppers, tomatoes, winter squash, watermelon): the earliest start, two weeks after the median last frost (April 15), is April 29[11]

Frost dates are probabilities from 1991 to 2020 weather records at one NOAA station, not a forecast. Any year can be earlier or later. The hardiness zone describes the average coldest winter night, not frost dates or summer heat. Spots inside the city can differ (ZIP table). Planting rules come from Colorado State University Extension's guide, written for Colorado. A local extension office may give dates tuned to the area. Planting and harvest dates marked GardenFacts calculation are simple arithmetic from the facts above, not advice from the source.
