Q.apple tree spots
There are little golden spots on the limbs of my young apple trees. Just purchased and planted.
Cedar apple rust can cause yellowish splotches on the branches. Here is some information about it: https://www.gardeningknowhow.com/edible/fruits/apples/cedar-apple-rust-control.htm
Newly purchased trees with this, or any other disease, should be returned to the dealer. You may want to get a refund and try trees from a different grower. You can have the tree branches examined by the Extension Service, who will tell you exactly what is going on.
