Troubleshooting
Steppe Sage problems — and how to fix them
Steppe Sage (Salvia tesquicola) 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.
Powdery mildew
In humid summers or crowded plantings, white powdery coating can appear on leaves; improve air circulation and avoid overhead watering. Severely affected stems can be cut back to encourage clean regrowth.
Winter waterlogging
Although cold-hardy, this sage is susceptible to crown rot if sitting in waterlogged soil over winter; on clay, raise the planting position or add a deep gravel collar around the crown.
