Troubleshooting
Pineapple Sage problems — and how to fix them
Pineapple Sage (Salvia elegans) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Frost dieback
The plant is killed or knocked back hard by freezing temperatures; lift or move pots under cover before the first frost in cold climates.
Leggy, floppy stems
Insufficient light or skipped pinching causes sprawling growth; cut back by a third in midsummer and grow in full sun to keep it bushy.
Powdery mildew
Crowded, damp foliage develops white mildew; thin stems for airflow and avoid wetting the leaves when watering.
Few autumn flowers
Over-feeding with nitrogen or too much shade suppresses the scarlet blooms; reduce feed and ensure full sun for the late-season display.

Most pineapple sage issues are care-mismatch, not bad luck. Dial in the basics:
