Rose Buds Cut on One Side – Beetle Damage, Not Disease

Insecticide: Rose spray for beetles.
Organic: Hand-pick at 7 AM (sleeping) → soapy water.

Clean cuts on buds = beetle feeding (likely rose chafer or Japanese beetle).

Beetles don't kill the plant, just ruin flowers. Daily morning patrol works well.

Petal drop in 1 day suggests thrips or water stress (see other answers).
