I have a weeping cherry and mine has a bunch of holes in the leaves too. I'm also wondering what would be best to treat it

No one?

I did a little looking around. Seems japanese beetles love weeping cherrys and other insects espcially ants (if your branchs touch the ground). They said to trim branchs to where they dont touch ground. And then apply bayer advanced pest & insect control. Or another one said to spray with Sevin insect spray and it will keep leafs healthy all summer. I guess its just insects eating it.

There was another post I seen that said if theres yellow spots and then the spot falls out and creates a hole, then that could be a type of fungus/disease and they recommended taking a few of the leafs to the local nursery cause different areas have different problems.

I guess I'm going to try the Bayer stuff and see how it works. My leafs are even worse this year then last. They keep going at it I'll have no tree left in 2-3 years. It does not help I live right in front of a corn field, I get all the insects/critters

Sometimes I forget I have google lol man I typed in holes in weeping cherry leafs and BAM I got slapped in the face!

Not sure about orig poster but my marks/holes have been there all summer. So I'm thinking it's a little of everything.

Is it too late in the year to treat. Should I treat now and next spring or just next spring.

Figured I'd post this for those like me that had no clue what a "systemic insecticide" was:

Most insecticide concentrates are sprayed on the plant where the insecticide material rests on the leaf or blade surface. A systemic insecticide works from the inside out instead of only on the exterior surface of the treated plant. The systemic action of Merit granules gives you two distinct advantages over conventional granules or sprays.
The first advantage is long term control. A surface application is constantly exposed to the elements. Rainfall, irrigation and sunlight all play a part in the demise of the insecticide. A systemic product is protected by the elements because it remains inside the plant's leaves, stems or blades.
The second advantage of systemic insecticides over conventional insecticides is that the entire plant is protected from attack by insects, grubs, mites. Root systems, stems and leaf portions of the plant all contain a small amount of your insecticide, not just the leaf surface.
