Troubleshooting
Royal Flush Split Rock problems — and how to fix them
Royal Flush Split Rock (Pleiospilos nelii 'Royal Flush') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Rot during leaf splitting
Watering while the old leaf pair is being resorbed almost always results in rot. The plant draws water from the old leaves to grow the new pair; extra water from the soil overwhelms this process and causes the new leaves to burst and rot. Withhold all water until the old leaves are papery and fully spent.
Multiple leaf pairs (over-watering symptom)
A healthy split rock produces one new leaf pair per year. If two or three pairs are present simultaneously, the plant has been watered during its rest phase. Remove excess water access and allow all but the newest pair to fully dry and resorb before resuming a correct watering schedule.
Loss of purple colour
The distinctive purple pigmentation of 'Royal Flush' fades to green in insufficient light. Ensure maximum direct indoor sun. Even a slightly dimmer spot can cause rapid colour loss. A grow light positioned 15–20 cm above the plant can supplement a south-facing window in winter.
