Rescuing my trees

My red delicious apple tree and my crimson maple aren't doing that well. The apple tree has just a few leaves left and the maple seems to be drying out. I went back to Hewitt's this morning to get some advice and it turns out that I need to soak these trees at least once every two days. We had a hot spell here and I missed a few waterings. He thought I could rescue the trees with this organic tree food so I got a bag and poured some around the base of each sad tree. Hopefully it'll work.

I was only outside for about five minutes, but of course I got bit by a couple of mosquitoes.
