Laurel-Leaved Rock Rose problems — and how to fix them
Laurel-Leaved Rock Rose (Cistus laurifolius) 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.
Honey fungus (Armillaria)
Cistus laurifolius shares the genus-wide susceptibility to honey fungus; affected plants wilt and die rapidly with no chemical treatment available. Inspect new sites for Armillaria rhizomorphs before planting, and remove all infected root material promptly.
Failure to regenerate after hard pruning
Like all Cistus, C. laurifolius will not break new growth from old, bare wood. Limit pruning to lightly trimming back the softer growth immediately after flowering; replace aging or wind-damaged specimens with young plants rather than cutting back hard.
