What's eating my double knock out rose?

Double Knock Out Roses share the same pest profile as the original Knock Out series. Aphids are the most reliable visitor, Japanese beetles cause summer damage, and deer will browse if access is easy. The dense double blooms can trap moisture and attract thrips inside flowers. Monitor buds closely during bloom.

Colonies on new shoots; honeydew and sooty mold follow; buds distorted before opening. Strong water spray; insecticidal soap or neem oil applied weekly until clear; encourage natural predators.

Foliage skeletonized; dense double blooms particularly attractive targets for adults in summer. Hand-pick in early morning; targeted pyrethrin spray; soil-applied milky spore for long-term grub reduction.

Petals show silver streaks or brown edges; tiny elongated insects visible inside blooms; flowers fail to open fully. Remove and discard affected blooms; spinosad or insecticidal soap spray; blue sticky traps to monitor population.
