In my talks at the Southeast Fruit and Vegetable Growers meeting in Savannah last week, I discussed sources of chill hour accumulations for different states in the Southeast. If you are outside the Southeast or want a more national view, the Midwestern Regional Climate Center offers a national map through their Vegetation Impact Program (VIP) which provides chill hours across the country. There is also a handy list of the number of chill hours needed for different types of fruit. You can see it at https://mrcc.isws.illinois.edu/VIP/indexChillHours.html#.
