Troubleshooting
Tricolor Sage problems — and how to fix them
Tricolor Sage (Salvia officinalis 'Tricolor') 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.
Frost damage
This variegated cultivar is less hardy than plain sage and can be killed in hard winters; mulch the crown or overwinter in a sheltered spot or container.
Root rot
Wet, heavy soil rots the roots; plant in gritty, free-draining soil and avoid winter waterlogging.
Reversion or fading variegation
Low light or over-feeding dulls the cream and pink; grow in full sun and prune out any all-green reverting shoots.
Powdery mildew
White film on leaves in humid, still air; thin for airflow and avoid wetting the foliage.
