Rosemary-Leaved Rock Rose problems — and how to fix them
Rosemary-Leaved Rock Rose (Cistus libanotis) 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.
Root rot and stem dieback
The most frequent killer; caused by overwatering or planting in heavy, poorly drained soil. Ensure sharp drainage and do not irrigate established plants except in prolonged summer drought.
Frost damage
Cold, wet winters can cause die-back of shoots and, in severe frosts below -5°C (23°F), loss of the whole plant. Plant in a sheltered south- or west-facing spot and avoid frost pockets.
