I am an extremely new gardener, and thought I could tackle an apple tree. We planted it about 1-2 months ago, and it's done well, apples looked good. It's a 2 year old tree. Recently, I started noticing yellowish/brown spots on the leaves and after much googling believe it to be Cedar Apple Rust. After researching, I've ordered some Immunox to spray it with.
The apples are now starting to look yuck, and I assume at this point no new ones will be coming correct?
If I treat this with the spray, is there hope the tree will recover next season? Should I be spraying it now, or wait until the off-season?
Any other advice about Cedar Apple Rust would be appreciated! Thanks!
