Chestnut-Flowered Sage problems — and how to fix them
Chestnut-Flowered Sage (Salvia castanea) 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.
Slug and snail damage
The soft, textured foliage is attractive to slugs and snails, especially in spring when new growth emerges; use grit mulch or organic slug deterrents around the base.
Winter waterlogging
Despite needing moisture, roots rot in waterlogged soil over winter; improve drainage by planting on a gentle slope or incorporating grit, and avoid heavy clay.
