White-Leaved Rock Rose problems — and how to fix them
White-Leaved Rock Rose (Cistus albidus) 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 in wet or clay soils
The number one killer of Cistus albidus in the UK; poorly drained winter soil causes rapid root death. Plant on a raised bed or add grit to improve drainage, and choose a sheltered south- or west-facing position.
Honey fungus (Armillaria)
Cistus albidus is susceptible to honey fungus, which can kill plants suddenly. There is no chemical cure; remove and dispose of affected roots away from the garden, and avoid replanting Cistus or other susceptible plants in the same spot.
