What are these spots on my apple tree - CAR? Anything I can spray / do? Also in 2nd pic (hard to see) inside the screen around the trunk the apple tree is growing leaves/suckers. Should I prune these & can I do it now during summer or should I wait until winter? TIA!
The spots look to me like Apple Cedar Rust. Over east, where I’m at, I’ve witnessed it on my young apple trees. I’d ignore it, and do. If it is ACR, I don’t believe there’s much to keep the leaves blemish free.
The pruning question's easy ‘tip pinch’ the terminal leaves off the small competing shoot. Let it’s remaining leaves feed the tree this season, then prune it flush with the trunk next spring.
I have seen those before. I also don't worry that much about it. It hasn't done much damage in my orchard.
