Diseased Crab Apple Tree
We have a diseased crab apple tree in our front yard, which drops leaves throught-out the summer. Is there something particular we should use to treat the tree and when is the best time of year to treat the tree?

It depends on what is really causing it to drop leaves. Here is a link that you can compare what they look like with photos. Once you know what it is you can hopefully treat the problem. http://www.extension.umn.edu/garden/diagnose/plant/fruit/apple/
