Apr 21, Because trees have the greatest need for nutrients in the spring, fertilizer should be applied between leaf drop in the fall and leafing out in the spring. The health and vigor of a tree may be improved by fertilizers up to July 1. Beyond that time, new growth stimulated by fertilizer may not have sufficient time to harden off before winter.

Sep 19, Many orchardists (think pecan, walnut, apple) fertilize their trees in the fall after harvest with great results, and you can do the same with your hard and soft mast bearing trees as well. Wait until the tree has unloaded its fruit, or the leaves begin changing colors to fertilize. In order to survive freezing temperatures during winter, trees must quickly acquire hardiness in the fall and maintain it until temperatures rise in spring.
Trees gradually become winter hardy as they are exposed to cold temperatures, finally becoming fully hardy in early winter.
