Troubleshooting
Nile Sage problems — and how to fix them
Nile Sage (Salvia nilotica) 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 rot in heavy or wet soil
Like most salvias, S. nilotica is intolerant of waterlogging; ensure sharp drainage and avoid planting in low-lying areas where water sits after rain.
Frost dieback
Stems die back below about −3°C; in marginal climates mulch the crown heavily in autumn and cut back dead stems in spring when new growth emerges from the rhizomes.
