Troubleshooting
Prosperity Rose problems — and how to fix them
Prosperity Rose (Rosa 'Prosperity') 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 spotting and leaf drop in humid, wet seasons. Limit it with fallen-leaf clearance, base watering, mulching and pruning to an open, well-ventilated canopy.
Powdery mildew
White coating on shoots and buds, worsened by dry roots and humid air or training against warm walls. Keep roots evenly moist, water at the base and ensure good air movement.
Aphids
Greenfly mass on soft new growth and buds, distorting shoots and depositing sticky honeydew. Hose off, squash by hand or rely on ladybirds and other predators.
Sparse bloom in deep shade
Though shade-tolerant, flowering thins and growth becomes leggy in heavy shade or hungry soil. Give the brightest practical position and feed well with organic matter.
