sour cheery leaf problem

Asked August 5, 2019, 4:30 PM EDT

Hello, I have planted a cheery tree this spring. Everything was fine, except recently I find a holes on new leaves. What is it and how to treat this? I didn't notice any pests with a glass magnifier. Thanks, Milla

Hello,

The smaller holes are likely symptoms of "shot hole" disease: https://pnwhandbooks.org/plantdisease/host-disease/cherry-prunus-spp-shothole

The bigger holes are from leafcutting bees (Megachilidae): https://entnemdept.ifas.ufl.edu/creatures/misc/bees/leafcutting_bees.htm

Aside from the minor damage to the cherry foliage, they are overwhelmingly beneficial.
