Troubleshooting
Cleveland Sage problems — and how to fix them
Cleveland Sage (Salvia clevelandii) 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 from summer irrigation
Phytophthora and Pythium root rots are triggered by summer watering on established plants; reduce or completely cease irrigation by June in Mediterranean-climate gardens.
Spittlebug (froghoppers)
Froghoppers (Philaenus spumarius) produce frothy masses on stems in spring and early summer; generally cosmetic but heavy infestations weaken young growth — blast off with a water jet.
