Lifelong Saxifrage problems — and how to fix them
Lifelong Saxifrage (Saxifraga paniculata) 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.
Overwatering and root rot
The leading cause of loss in cultivation; ensure containers and beds drain freely and never allow the plant to sit in a saucer of water. Signs include mushy rosette bases and yellowing leaves.
Vine weevil
Adult weevils notch the leaf margins in summer and larvae destroy roots over winter; use nematode drenches (Steinernema kraussei) in late summer and check the root zone of container plants each spring.
