What's eating my blaze improved rose?
Japanese beetle (US)
Signs: Adults skeletonize foliage and shred petals throughout summer, often congregating in large numbers.
Control: Hand-pick at dawn into soapy water daily; apply neem oil spray; use milky spore or beneficial nematodes for grubs.
Aphids
Signs: Colonies develop rapidly on new cane growth, causing sticky, distorted foliage and reduced vigour.
Control: Blast off with water hose; insecticidal soap or neem oil spray; avoid over-fertilizing with nitrogen.
Rose sawfly (larva)
Signs: Larvae graze leaf undersides in late spring, causing translucent windows that turn brown quickly.
Control: Inspect canes weekly from May; hand-remove larvae; spray pyrethrin for moderate-to-heavy attacks.
Rabbits
Signs: Clean-cut gnaw marks on lower canes at ground level, especially in late winter and early spring.
Control: Wrap lower cane bases with wire mesh guards; use granular repellent around the planting area.
