Curly-Leaved Rock Rose problems — and how to fix them
Curly-Leaved Rock Rose (Cistus crispus) 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 wet and root rot
The greatest threat in UK gardens; prolonged waterlogging in cold, wet winters rapidly kills the root system. Improve drainage before planting, apply a grit mulch around the crown, and choose a sheltered south-facing site.
Legginess after several years
Cistus crispus becomes woody and sparse with age; it does not regenerate from hard pruning. Replace leggy plants after 5–8 years, propagating replacements from semi-ripe cuttings taken in late summer.
