Fruit trees need a set number of cold hours in winter before they bloom well. Nurseries rate varieties by it: low-chill varieties need roughly 100 to 400 hours, many peaches and plums 500 to 900, and most apples and sweet cherries 800 to 1,200 or more. Your variety's rating is the number to compare with the 1,484 hours Nashville had last winter.

Chill hours here are hours at or below 45°F, estimated hour by hour from the station's daily high and low. Checked against measured hourly air temperature at 39 NOAA reference stations last winter, the estimate was within 1.9% of the measured count at the median station. How it is checked.
