Brown leaves on apple trees - please help!
Hello there, Ive got 3 young apple trees that were planted last winter (a fan trained Cox, Katy and Red Sentinel that have all blossomed beautifully, have new shoots growing but now have leaves curling, turning brown and dying back; some of the smaller fruit are doing this too. I’ve googled the problem but there seems to be quite a few possibilities for what the problem is. I can’t see any infestation apart from one or two burrowed leaves but this could be unrelated to the main problem. Any ideas what it is and what course of action to take if one is required? Many thanks!
