Munby's Rock Rose problems — and how to fix them
Munby's Rock Rose (Cistus munbyi) 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.
Frost damage and dieback
More frost-tender than many rock roses due to its North African coastal origin; temperatures below 0°C (32°F) can damage stems. Protect with horticultural fleece or grow in a pot that can be moved under cover in winter.
Root rot in wet soils
Like all Cistus, it is highly intolerant of winter wet; plant in very gritty, free-draining soil or a raised bed to prevent root and collar rot.
