Troubleshooting
Crimson-Spot Rock Rose problems — and how to fix them
Crimson-Spot Rock Rose (Cistus ladanifer) 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.
Chlorosis on alkaline soils
Unlike most other Cistus, C. ladanifer is sensitive to high soil pH as plants mature, developing yellowing between leaf veins. If planting on chalk or limestone, acidify the planting hole with composted bark and monitor pH over time; severe cases may require replacement.
No recovery from hard pruning
Cistus ladanifer cannot regenerate from cuts into old, woody stems; any pruning should be restricted to removing dead, damaged, or straggly shoots promptly after flowering. Leggy specimens are best replaced with young plants propagated from cuttings.
