Troubleshooting
Blanco's Sage problems — and how to fix them
Blanco's Sage (Salvia blancoana) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root and crown rot
Wet, cold, heavy soil over winter is the primary killer; ensure the planting site has excellent drainage or grow in raised beds amended with grit. Avoid mulching tightly around the crown.
Botrytis (grey mould)
In humid, poorly ventilated conditions the grey foliage can harbour Botrytis cinerea; space plants generously for airflow and remove any dead or damaged stems promptly.
