I planted four Patmore Green Ash trees in my yard and they all have circular hole bite marks on all the leaves. I cannot see any insects on them. Do you have any idea what might be eating the leaves and how I can get rid of them?

You mentioned that your holes are "circular". This sounds like the work of leaf cutter bees. They cut very circular holes starting at the edge of the leaf. If the holes are in the middle of the leaf, it is not leafcutter bees. You can go to Google and type in "leaf cutter bee damage" click on "image" to see pictures of the holes they make. Earwigs make holes in leaves, but they are irregular, not circular. Strawberry root weevil make notches on the edges of leaves, more like a half circle. You can bring in a sample of your leaves and we can take a look at them and see if we can tell what is causing the holes. It costs $1 per sample.

- I have a Blierana flowering plum tree that failed to leaf out fully this spring. I looked at it yesterday and found at least fifty places on the branches where a snake-like resin/sap has been pushed out of the branch. Is this a borer doing damage? What do I do? Should I remove the tree to prevent further damage to surrounding trees? Is there something I can spray? Can I ever plant a tree in this same spot?
