Average Frost Dates
Last & First and How to Find Them
Why do you need to know the average frost dates, both the last and the first? Because they determine how early or how late you can plant. The average frost date in the spring, the last date, allows you to know when you can safely put seeds or seedlings in the ground. Too soon and you run the risk of having them damaged or even killed by freezing temperatures. (The last date is winter's last frost, but appears at the beginning of the growing season. So, you use the last one first.)
The average frost date in the fall, the first date, helps determine how long plants can survive before having to be harvested. Working backward from that date tells you when to plant a cool weather crop, such as lettuce, and still have time to harvest.
The Nuts & Bolts
Two methods are provided for finding the dates in your area.
First, check a list of cities and determine which one is most like where you live, then use the dates provided. Just click the link below, Frost Dates By City, to view a list of cities.
The second method requires you to know your zip code. That's easy. Clicking the link below, Frost Dates By Zip Code, will open another window where you can enter your zip code and receive both dates. This second method also requires you to input a little more info.
It may look difficult when inputting data by zip code, but it isn't. On the left (on the new page) change percentages to 50% and you will be fine. If your exact spot doesn't show up like where I live, pick a spot near you. My 2 choices are 15 miles west or 15 miles south-southeast. They only differ by a three days for last frost and two days for first frost.
Remember, they are averages and will vary some from year to year. If an unusual cold snap is predicted by your reliable weather person, you may need to cover your crop for protection forn a few days. Or replant. Oh, well.
