June Bugs and Leaf Holes on Knockout Roses

June Bugs and Leaf Holes on Knockout Roses

June bugs (green June beetles) don't typically damage roses – they prefer ripe fruit. The holes in leaves are from:

  • Beetles: Ragged edges, especially leaf margins.
  • Caterpillars: Smooth, round/oval holes in leaf centers.

Control

Any rose insecticide handles both. Deadheading (snapping off spent blooms) is correct – it encourages rebloom.

Outlook

Knockouts are tough shrubs. With time and basic care, they'll grow vigorously and bloom heavily.
