Q: What is the average day of the first killing frost in Payson?
A: According to the Cooperative Extension Service website, Payson is in Zone 3, High Altitude Desert (Elevation 3,500-5,000 feet). Our growing season about 200 to 220 days long and the spring frosts are generally over by April 10. So, starting around April 10 and adding 200 days, to be conservative, we can expect our first killing frost about the last week of October or, being less conservative, sometime between mid- and late November.
