Many-spiked Sage problems — and how to fix them
Many-spiked Sage (Salvia polystachya) 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.
Stem breakage
The brittle hollow stems are prone to snapping in wind; site plants in a sheltered spot among other vegetation or provide loose staking before flowering spikes elongate.
Root rot in wet winters
Plants lose their roots in cold, waterlogged soil over winter; in zones 8–9 mulch heavily in autumn and ensure raised, well-drained beds to improve survival.
