What's eating my harlow carr rose?

Aphids (Macrosiphum rosae)

Signs: Colonies on fresh shoots and budding stems; leaves curl and distort; sticky waste encourages sooty mould

Control: Knock off with water; spray insecticidal soap or neem oil; plant companion flowers to attract aphid predators

Rose sawfly (Arge pagana / Blennocampa phyllocolpa)

Signs: Tightly rolled leaves or skeletonised leaflets where larvae feed; damage most visible May through July

Control: Hand-remove affected leaves; apply pyrethrin spray if colonies are spreading; avoid broad-spectrum pesticides that kill beneficial insects

Black spot (Diplocarpon rosae)

Signs: Dark blotches on leaves causing yellowing and premature leaf fall; weakens flowering and overall vigour

Control: Collect fallen leaves; spray with myclobutanil or trifloxystrobin; thin dense growth for airflow

Rabbits

Signs: Stems gnawed near the base, sometimes severed; bark chewed away; damage worst in winter when other food is scarce

Control: Fit spiral guards around stems; protect beds with low wire-mesh fencing; reapply rabbit deterrent spray after rain
