Queen Elizabeth Rose problems — and how to fix them
Queen Elizabeth Rose (Rosa 'Queen Elizabeth') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Blackspot
Black-edged spots and leaf drop in humid, wet conditions; remove infected leaves, water at the base and ensure good airflow.
Powdery mildew
White film on young leaves and buds in still, humid air; prune for airflow and keep plants evenly watered.
Leggy, bare base
This tall grandiflora can grow leggy with sparse lower growth; prune hard in late winter to encourage bushier, well-clothed canes.
Aphids
Cluster on soft new shoots and buds; dislodge with water, encourage ladybirds or use insecticidal soap.
