Should You Remove Insect-Damaged Rose Leaves?

Chewed rose leaves look unsightly, but the plant needs every green surface for photosynthesis. The rule: if more than half the leaf remains, leave it. If less than half, remove the entire leaflet or leaf.

Pruning Guidelines

• Cut at the base of the leaflet (where it meets the rachis) or the whole leaf at the cane.
• Do not strip the plant; roses can produce three sets of leaves per season.
• Removing heavily damaged leaves reduces pest habitat and improves appearance.

New growth emerges within 1-2 weeks. Focus on controlling the pest (beetles, sawflies, etc.) rather than obsessing over damaged foliage.
