Burnt-Looking Rose Petals: Frost, Thrips, or Rose Midge?

Zone 7 gardener: roses blooming with outer petals looking burnt. 6-7 hours morning sun.

Three Possibilities

1. Frost nip just before opening (if all roses affected).
2. Thrips—tiny insects sucking petals, leaving brown dots.
3. Rose midge—lays eggs at bud base, larvae eat petals, leaving pinhole.

Action

If not frost, apply rose insecticide for thrips/midge. Check bud base for pinhole.
