OK I know that not many people on here are apple tree experts but I have a problem and it is stressing me out. So I have two Apple trees a honey crisp and a Fuji and the bark is Turing yellow on both if anyone knows how to fix this/ what the problem is please let me know! The one on the left is honey crisp and on the right if Fuji. (The leaves are turning black on the tips and bugs swarm the honey crisp)
