Apple tree leaves are turning a light green color and drying up.?

Question

It appears I have a sick tree. I don't see any bugs on it. Any ideas about what may be wrong with it and how to improve it's health? It has no apples as we pruned it March 2007.

Answer 1

Try watering it  with a hose on a slow flow for about 1/2 hour every other day and fertilizing with a basic plant or tree food.
