Blanc Double de Coubert Rose problems — and how to fix them
Blanc Double de Coubert Rose (Rosa 'Blanc Double de Coubert') 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.
Few or no hips
The double blooms set little fruit, so gardeners wanting autumn hips may be disappointed. Grow a single rugosa alongside if hips are the goal.
Rain-spoiled blooms
Delicate papery white petals brown and ball after heavy rain. An open, sunny, airy position helps flowers dry and reduces marking.
Suckering habit
Spreads by suckers on its own roots. Pull or dig out unwanted suckers, or use the trait deliberately for an informal hedge.
Chlorosis on alkaline soil
Yellow leaves with green veins signal lime intolerance. Plant in neutral-to-acid soil, avoid lime, and mulch with acidic organic matter.
