Caucasian Draba problems — and how to fix them
Caucasian Draba (Draba bruniifolia) 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 and root rot
Wet, poorly drained soil — especially over winter — rapidly kills the central rosette; plant in a raised scree bed or vertical rock crevice and mulch the crown with fine grit.
Smothering by vigorous neighbours
As a slow-growing miniature it is easily overrun by faster-spreading plants; site it away from spreading thymes, sedums, or other mat-formers and check annually.
