I am choosing apple trees. The supplier asked about freeze hours in our county. My question was how many freeze hours does Frederick county have in an average year.

Hi- please see this page for the U.S. chill hours map.

Frederick Co. experiences at least 1400 chill hours/year.
Any location in Frederick Co. is suitable for growing the vast majority of available cultivars.
