Troubleshooting
Gentle Hermione Rose problems — and how to fix them
Gentle Hermione Rose (Rosa 'Gentle Hermione') 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
Dark blotches with yellowing leaves in wet summers; though fairly resistant, improve airflow, clear fallen leaves, and avoid overhead watering.
Aphids
Clusters on soft new shoots and buds in spring; dislodge with water, encourage ladybirds, or use insecticidal soap before they distort growth.
Balling of blooms
Petal-packed flowers can fail to open and rot in prolonged wet weather; gently peel away the outer browned petals to release the bloom.
Powdery mildew
White coating on leaves and stems in dry-root, humid conditions; keep roots evenly moist and prune for open structure.
