Use this frost date calendar as a gardening guide to know the average first and last dates of frost in spring and fall measured over a 30-year period in your local area.
Frost dates help us know when to plant vegetables and flowers in the garden and when to protect plants from frost.
The Best Time To Plant
As a general guideline, it is recommended that you plant your vegetable and flower garden two weeks after your last spring frost date.
As always, it’s possible that a late frost will show up unexpectedly. Use this calendar to know approximate timing for your area to plant your garden. The frost date calendar also guides us to know how long the growing season will be.
Understanding Frost and Freeze
For reference, a light freeze or frost happens when temperatures fall below freezing by a few degrees only for a few hours. Some hardy plants may not see damage.
A hard freeze happens when four consecutive hours of air temperatures dip below 25 degrees Fahrenheit. Many tender plants can survive a brief frost or freeze but very few can survive a hard freeze.
