Troubleshooting
Caradonna Salvia problems — and how to fix them
Caradonna Salvia (Salvia nemorosa 'Caradonna') 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.
Flopping after the first flush
Stems can splay open, especially in rich soil or shade. Grow in full sun and lean soil; shear back spent spikes to encourage a tidy rebloom.
Fewer reblooms without deadheading
Spent flower spikes slow further flowering. Cut back faded spikes promptly to prompt a second, lighter flush later in summer.
Crown rot in wet soil
Heavy, waterlogged winter soil rots the crown. Plant in sharply drained ground and avoid overwatering, particularly in clay.
Powdery mildew
Occasional in humid, crowded conditions. Space plants for airflow and avoid wetting the foliage to keep leaves clean.
