Small-Flowered Rock Rose problems — and how to fix them
Small-Flowered Rock Rose (Cistus parviflorus) 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.
Winter waterlogging and root rot
Heavy or poorly drained soils in winter are fatal; ensure a very gritty growing medium and consider a raised or sloped position to shed excess rainfall away from the root zone.
Frost dieback in exposed sites
Although moderately hardy to around -5°C (23°F), plants in frost pockets or exposed, windy positions suffer significant shoot dieback; site against a south-facing wall or fence for additional shelter.
