What's eating my penelope rose?
Aphids
Signs: Dense colonies on new growth and buds; sticky honeydew, leaf curl, and stunted flowering stems.
Control: Strong water spray to dislodge; neem oil or insecticidal soap weekly; encourage ladybugs and parasitic wasps.
Rose Sawfly (rose slug)
Signs: Translucent window-pane patches on upper leaf surface in spring as pale larvae graze tissue.
Control: Inspect and hand-pick larvae; spinosad or insecticidal soap on undersides; remove badly affected leaves.
