Stribrny's Saxifrage problems — and how to fix them
Stribrny's Saxifrage (Saxifraga stribrnyi) 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.
Crown rot
The most serious problem; caused by excess winter moisture sitting on the rosette. Prevent by growing in an alpine house, ensuring perfect drainage, and placing a collar of grit around the neck of the plant.
Vine weevil
Larvae feed on the roots and can kill plants quickly; check the root zone when repotting and apply a biological control (Steinernema kraussei nematodes) in late summer.
