I have 3 Apple trees. Each year the leaves and then the fruit get covered with brown spots. What is it, and what can I do to prevent it? I get lots of apples but I have to through them away because of this problem. Thank you
There are a couple of fungal disorders that can cause this. There is now need to throw the apples out though since it is a cosmetic issue, not something that makes the apples inedible or unusable in any way. If you want perfect apple though, you’ll have to spray them regularly starting in spring with a fruit tree spray that contains a fungicide. If you drop by the garden center in April, we’ll set you up with what you’ll need.
