please can anyone help , my apple tree has been fine for years but this year the leaves are covered in yellow  blotches and on the underside they are like hard blisters, can anyone tell me what the problem is,and a cure, if any.thank you

Your problem sounds a lot like cedar-apple rust. I don't know of any home or organic remedies for it so you'll have to go to a good garden center and ask for a chemical treatment. If left, in a few years the disease will the tree.
