Mediterranean Sage problems — and how to fix them
Mediterranean Sage (Salvia aethiopis) 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.
Invasive spread by seed
Mature plants detach at the base and tumble, dispersing up to 100,000 seeds each; remove and bag flower stems before seed set; the plant is a listed noxious weed in several western US states and must not be introduced there.
Crown rot in wet winters
Despite cold hardiness, the woolly crown is vulnerable to fungal rot in persistently waterlogged soils; plant on a slope or in raised beds and avoid mulching over the crown.
