Troubleshooting
Trumpeter Rose problems — and how to fix them
Trumpeter Rose (Rosa 'Trumpeter') 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.
Aphids
Cluster on the abundant new buds; rinse off with water or use insecticidal soap before colonies build up.
Occasional blackspot
Resistant but possible in prolonged wet; clear fallen leaves and water at the base to keep foliage dry.
Spent-bloom buildup
Its non-stop clusters leave many faded florets; deadhead trusses to a strong leaf to keep the show going.
Stem dieback in hard winters
At the cold edge of its range, protect the base with mulch and prune out dead wood in spring.
