Hello,
My espallier apple tree has developed leaf curl and the blossom has fallen off but only on the top two tiers, the bottom three tiers are fine, full of blossom and young leaves. It did the same late last year, any ideas?. I have sprayed with a combined bug and fungus killer last month twice and given the tree a winter wash in January
