Fruit Trees no Leaves

Asked August 8, 2018, 8:03 AM EDT

I have apple trees that almost all the leaves have fallen off on the west facing side of the tree. as I walk through my neighborhood most of the apple trees have the same condition. I want to know what the problem is and also what can I do about it. The trees have a grayish fungus on the branches and the leaves have spots.

The green patches on the trunk/bark are lichens. The grown on mature trees and are not a cause for decline.
We do see some cracks in the trunk. These may be cankers or growth cracks and there is no control.

Fruit trees especially apple are a challenge to grow as they are so susceptible to insect and disease issues. They require careful management and a spray schedule for control. Take a look at our website for common problems of apples. They can be susceptible to fungal diseases, apple scab, rust, fire blight, etc. All can cause leaf spots and defoliation. You will have to identify what you are dealing with. It is too late to spray this year. Practice good sanitation by raking up fallen leaves and removing infested fruit. You can also cut open the fruit and look for insect issues.
In the future select disease resistant varieties.
Also, next season as soon as the tree leafs out and you notice symptoms send us photos so we can see what you may be dealing with.
