Troubleshooting
Compassion Rose problems — and how to fix them
Compassion Rose (Rosa 'Compassion') 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.
Black spot
Possible in prolonged wet weather despite good resistance; gather fallen leaves and water at the base to limit infection.
Aphids
Green or pink colonies on tender shoots and buds in spring; wash off with water or use insecticidal soap before damage occurs.
Bare base
Climbers trained too vertically flower only at the top; bend and tie canes horizontally to break apical dominance and bloom lower down.
Powdery mildew
White powdery growth on young leaves in dry, stagnant spots; improve air circulation and avoid drought stress at the roots.
