tiny holes in hosta

17 years ago

Have grown hosta for many years, this is new to me. Tiny white spots on my mini hostas which then become round holes, almost like pinholes. This happened almost overnight. Not irregular holes like slugs. Checked at night with flashlight, did not see any insects. Leaves are riddled with many tiny holes. Do not see this on larger size plants at this time.

These are in a raised bed under a river birch tree. Had japanese beetle damage to the tree (first time) last year, no tree damage yet but waiting for the JB's to hatch. Wonder if there could be a connection. We have used the milky spore stuff on the lawn & gardens which will hopefully help the JB invasion this year.
