Pest identification
What's eating my compassion rose?
Aphids (Macrosiphum rosae — rose aphid)
Signs: Clusters of green or pink soft insects on new shoots and buds; sticky honeydew, sooty mould, and distorted growth.
Control: Blast off with a strong jet of water; encourage ladybirds and lacewings. Use insecticidal soap or neem oil spray for heavy infestations.
Rose sawfly larvae (Arge ochropus / Endelomyia aethiops)
Signs: Skeletonised or window-paned leaflets; caterpillar-like pale larvae feeding on leaf undersides, often from late spring.
Control: Pick larvae off by hand; apply pyrethrin-based spray or spinosad as a targeted drench if populations are high.
Black spot (Diplocarpon rosae)
Signs: Circular black or dark-brown spots with yellow halos on leaves; severe defoliation by midsummer if untreated.
Control: Remove and bin (not compost) affected leaves; improve airflow by pruning. Apply a copper-based or myclobutanil fungicide at 7–14-day intervals.
Deer
Signs: Ragged, torn stems and foliage browsed overnight, especially on new growth and buds; no clean cut.
Control: Install 1.5–1.8 m deer fencing or use deer-repellent sprays (egg-solid or capsaicin-based); re-apply after rain.
