Blue-flowered African Sage problems — and how to fix them
Blue-flowered African Sage (Salvia africana-caerulea) 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 poorly drained soil
Standing water in winter rapidly kills established plants; if growing in containers ensure drainage holes are unobstructed and use a terracotta pot rather than plastic.
Spider mites in hot, dry indoor conditions
When overwintered under glass, fine webbing and stippled leaves signal spider mites; raise humidity around the pot, remove with a strong water spray, and apply insecticidal soap if persistent.
