Waldensian Saxifrage problems — and how to fix them
Waldensian Saxifrage (Saxifraga valdensis) 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.
Collar rot from winter moisture
The very tight, dense cushions are extremely prone to fungal collar rot if moisture sits around the crown in winter; alpine-house cultivation with an open cold frame top or overhead glass protection outdoors is strongly recommended.
Slugs and snails
Even the smallest slugs can devastate a compact cushion overnight; apply copper tape around trough rims and use iron phosphate pellets (wildlife-safe) in spring when the plant resumes growth.
