Troubleshooting
Summit Sage problems — and how to fix them
Summit Sage (Salvia summa) 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.
Root rot in heavy or wet soil
Its native limestone cliff habitat drains perfectly; any compacted or poorly drained garden soil will cause root rot — raised beds with gritty, alkaline compost are strongly recommended.
Slug and snail damage
The compact, low-growing habit makes young foliage and flowers vulnerable to slugs; use iron-phosphate pellets and gritty mulch around the crowns to deter molluscs.
