What's eating my constance spry rose?
Aphids (Macrosiphum rosae)
Signs: Dense colonies on soft shoot tips and bud stalks; honeydew leads to sooty mould and bud distortion.
Control: Encourage beneficial insects; spray with insecticidal soap or diluted neem oil, targeting undersides of leaves and growing tips.
Rose sawfly larvae
Signs: Window-paned or fully skeletonised leaflets; pale, multi-legged larvae visible on undersides, active late spring to early summer.
Control: Hand-pick larvae; spray with a pyrethrin or spinosad product in the evening to avoid pollinators.
Black spot (Diplocarpon rosae)
Signs: Dark spots with feathery edges on upper leaf surface, yellowing and early leaf drop reducing vigour.
Control: Clear fallen leaves; mulch to prevent soil splash. Apply fungicide (myclobutanil or trifloxystrobin) preventively in damp conditions.
Rabbits
Signs: Clean 45-degree nibbles on young stems at ground level, particularly on newly planted or low-branching growth.
Control: Wrap base stems in spiral tree guards or fine wire mesh to 60 cm height; remove guards to check for stem rub in summer.
