Troubleshooting
Cupcake Miniature Rose problems — and how to fix them
Cupcake Miniature Rose (Rosa 'Cupcake') 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
Fungal disease causing black-edged spots and leaf drop in damp conditions; improve airflow, water at the base and remove infected leaves.
Powdery mildew
White coating on young leaves and buds in humid, crowded conditions; space plants, prune for airflow and avoid drought stress.
Aphids
Cluster on soft new shoots and buds; dislodge with water, encourage ladybirds or use insecticidal soap.
Poor flowering
Usually too little light or over-feeding with nitrogen; ensure 6+ hours of sun and a balanced rose feed.
