Troubleshooting
Iceberg Rose problems — and how to fix them
Iceberg Rose (Rosa 'Iceberg') 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 in wet climates
Generally resistant but can spot in prolonged damp; remove affected leaves and keep foliage dry.
Aphids
Cluster on flower buds and new shoots; dislodge with water or treat with insecticidal soap.
Spent-bloom clutter
Heavy flowering leaves many faded clusters; regular deadheading keeps it tidy and prolongs bloom.
Spindly winter growth
Can become twiggy if unpruned; cut back hard in late winter to maintain a dense, shapely bush.
