Brown Apple Leaves

Unfortunately, we can’t see the leaf clearly. Also, the best way to diagnose leaf damage is with a loop or hand magnifier. However, it is not a good thing when the fruit tree’s leaves begin to brown because it hinders photosynthesis and the ability of the tree to obtain nutrients. Browning of the leaves can be due to a variety of reasons: infestation of aphids, mealybugs, scale, caterpillars, beetles; fungal or other diseases as well as environmental conditions such as poor-draining soil, inadequate moisture or early frost/freeze damage. We suggest you take a few of the browning leaves to a local garden center or the Nevada Extension Agency for confirmation of the problem.
