Hi last year I bought patio peach, apricot and nectarine trees, for some reason some of the leaves on the apricot tree are wilting, there's no obvious signs of insects or disease that I can see. The nectarine blossom is also brown and dead on some of the branches. I live in south west Wales so the climate is quite mild are you able to give me some advice on what I may be doing wrong?
