Beach Salvia problems — and how to fix them
Beach Salvia (Salvia africana-lutea) 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
Can occur in warm, humid conditions with poor air circulation; improve spacing between plants, avoid overhead watering, and apply a copper-based fungicide at first sign.
Legginess from inadequate pruning
Without an annual cut-back by one-third in late spring after flowering, the plant becomes woody and open; hard pruning into bare wood is risky — always leave some green foliage on the stem.
