My apple tree is about 5 years old. for the last couple of years the tree produces many apples but when they get to be about the size of a quarter they gradually fall off until there none left at all. Can you tell me what causes that?

Sometimes apples do this ,naturally, to reduce a fruit set that is too heavy. It can also be due to a lack of water, or light to the inner part of the tree.
