Do you have any Junipers or Red Cedars nearby? It could be Apple Cedar Rust,
which is a symbiotic growth between those trees and your apple trees. I have
tried
various sprays to get rid of it, but finally pulled out two Red Cedars near my
apple
trees to stop it. Look for an ugly growth on the Junipers to match the apple
tree leaf
problem. Those trees could be a distance away, say on your neighbors property,
so
then you have to do the chemical thing.

I just planted a new apple tree and it is growing fine. Has put out
about 14 inches of grown since the winter.

I am seeing some leaves that have a golden tan-brown spot on the leaf?
What is this and what can I do to get rid of it?
