Mountain Germander problems — and how to fix them
Mountain Germander (Teucrium montanum) 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 in wet winters
The primary threat; perfect drainage — ideally in a raised rock garden or scree bed — is the best preventive measure, as no amount of treatment reverses crown rot once established.

Newly planted specimens are vulnerable to slug damage in spring; apply grit mulch around the crown, which deters slugs and improves drainage simultaneously.
