Rudbeckia 'Goldsturm' problems — and how to fix them
Rudbeckia 'Goldsturm' (Rudbeckia fulgida var. sullivantii 'Goldsturm') 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.
Powdery mildew
White coating on leaves in humid, crowded conditions late in the season. Improve airflow, avoid overhead watering and cut back affected foliage.
Crown and root rot
Caused by wet, poorly drained winter soil. Plant in free-draining ground and avoid mulching directly over the crown.
Slugs and snails on new growth
Young spring shoots are vulnerable. Use barriers or wildlife-safe controls until foliage toughens.
Flopping stems
Over-rich soil, too much shade or excess nitrogen causes lax growth. Site in full sun and avoid heavy feeding.
