Do you think this is a disease or a bug? There's some browning leaves on tips and some leaves are curled. There's no fungus or powder.
and its so random and MINOR...
that i would speculate on hail ....
regardless.. nothing i would do anything about..
Don't know about those particular holes but the tip die-back is common on this one around here, where there are significant numbers of plantings to observe.
The holes that are common on Prunus here are those caused by Prunus Shot-hole Fungus. As the name suggests, heavily infested plants look as those pellets have been shot through them.
I suspected earwigs because they are eating my butterfly bushes in the back. When I went out at night, I did see earwigs, along with a beetle and some other bugs. I also have the brown spots indicative of shot hole. It rained all of June here so I wouldn't be surprised if it was a fungus. I'm afraid it's worse than you may think, as all of this is happening very quickly. Any ideas where I should start. Do I spray for bugs? Should I have the leaves tested for shot hole disease?
OK - here's the thing :-) Bugs eat holes in foliage. Unless they are skeletonizing the leaves and defoliating the trees, it is almost always a cosmetic issue - unsightly perhaps but no harm to the tree.
Brown "spots" are not necessarily indicative of shot hole - actual holes/missing tissue in the leaf are more symptomatic of that problem. As bboy described, it looks like someone peppered the tree with buckshot. Again, on deciduous members of the genus, shot hole is more cosmetic than harmful and attempting to treat now is likely to cause more issues than help. This disease is often associated with excessive overhead watering, either from rain or sprinklers and any sort of treatment now is not going to be of much value. Just be sure to clean up well in fall and get rid of the fallen leaves.
I guess the gist of this post is that we need to exercise a degree of tolerance :-) We are dealing with nature and flawless foliage is not the norm, despite what we prefer. By all means treat IF the situation warrants it. In this case, I don't see any reason to believe that it does. All in all, your little tree looks pretty darn good for a weeping cherry.
