Growing season length (days between last spring 28°F frost and first fall 28°F frost) ranges from under 90 days in the Northern Rockies to over 300 days in South Florida. Median growing season for your specific county shows on the frost-date page.
Match crop maturity to growing season length. Frost-date pages show median, short-year (10%), and long-year (90%) growing season lengths.
