Troubleshooting
Mouse Head Plant problems — and how to fix them
Mouse Head Plant (Muiria hortenseae) 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.
Rotting of the old leaf body
The old sheath must be allowed to dry and shrink naturally before the new body emerges. Do not remove the old skin and do not overwater during this transition period.
Root rot from excessive watering
Despite needing more regular moisture than many mesembs, standing wet soil will still cause root rot. Ensure excellent drainage and always allow the top centimetre of soil to dry before re-watering.
Surface fungal spots
The downy surface can trap moisture and develop fungal spots if humidity is too high or ventilation is poor. Improve airflow and avoid wetting the leaf surface when watering.
