Hi can you please help? I’m not sure if there anything that I can do to save my Granny Smith apple tree? It is 12+ years old and I have just noticed some sort of white fungus growing on a couple of the branches. Not sure if I should cut as much off as possible or is there some sort of spray I can apply? It is a major branch so it would cause a lot of stress to the tree anyway if I were to attempt a cut and I don’t think it would get it all either. Your help would be much appreciated. Thanks, Rima
