Troubleshooting
Golden Sage problems — and how to fix them
Golden Sage (Salvia officinalis 'Icterina') 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.
Root rot from wet soil
Cold, wet, badly drained soil rots the woody base, the commonest cause of death. Use gritty, free-draining soil and water sparingly, especially over winter.
Reversion to plain green
Variegated sage sometimes throws out solid green shoots that grow more vigorously. Cut these out promptly or they will gradually crowd out the gold-marked growth.
Woody, leggy with age
Old plants go bare and woody at the centre. Trim lightly after the main growth flush and replace every few years from cuttings to keep plants dense and productive.
Powdery mildew
A white film on the soft leaves in humid, crowded, low-light spots. Give full sun, space plants for airflow, and avoid overhead watering.
Prevent golden sage problems before they start
Most golden sage issues are care-mismatch, not bad luck. Dial in the basics:
