Question
Recently my maple tree is showing symptoms of yellow leaves, ants on the tree. For the apple tree, the leaves are going off. I'm in Ontario.  It is not that cold for yellow leaves yet.  Ohtere trees are fine.
I water the trees not so often as grass and plants since I think they have stronger and deeper root systems. I can mail you the photo that I took.  Is there any email address that I can attach photos please?

Thanks,

Li

Answer
Li,

I could not tell from the images of the apple.  Take sdample leaves to your local extension office.  

Now the maple is a variegated plant I am assuming, if is not it sures looks variegated from the images.  The leaves with the spots I do not believe should concern you.  Take samples of these to the extension office with the apple leaves.

Good l;uck
