What seems to be happening with some apple trees that we have seen in Owen County as well as in the Jackson County areas? The trees appear to have a problem with the leaves turning brown and dropping.
The Gardener’s Answer
Apples in Kentucky are susceptible to a variety of bacterial and fungal diseases. The most common we see are cedar apple rust, scab, fire blight and powdery mildew. Some varieties of apples are more resistant than others, but growing environments play an important role in the difference between a healthy tree and a stressed or diseased one.
From the symptoms you described, it sounds like apple scab may be what you are seeing. Brown foliage can also be an indication of root injury or stress related to uneven moisture levels. Too much moisture or not enough have the same physical appearance. The Owen County horticulture/agriculture agents with the Cooperative Extension Service can give you their insight as well.
