Fruit trees in the U.S. Department of Agriculture Plant Hardiness Zone Seven should be pruned in late winter, between January and February. Pruning these trees while they are dormant in the winter revitalizes them for significant growth in spring.
Pruning between January and February also promotes the growth of larger, better-tasting fruit. However, trimming the branches back results in some fruit loss initially.
The zone encompasses a region that mainly includes southeast New Mexico, Oklahoma, northern Texas, northern Arkansas, Tennessee, northern Alabama, northern Mississippi, northern Georgia, northwestern North Carolina and Virginia, as well as sporadic areas in the Western United States. The zone averages winter low temperatures of 0 to 10 degrees Fahrenheit.
