Troubleshooting
Wall Monanthes problems — and how to fix them
Wall Monanthes (Monanthes muralis) 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.
Desiccation in dry indoor air
Unlike typical succulents, Monanthes muralis can suffer in very dry indoor environments, particularly near radiators. Leaves shrivel and drop. Move to a more humid spot or use a pebble tray with water below the pot.
Root rot from compacted or poorly draining soil
Despite its greater moisture tolerance, waterlogged roots will rot. Ensure the pot has drainage holes and the compost contains enough grit or perlite to prevent compaction and standing water.
Mealybugs and scale insects
The dense, low mat of rosettes provides shelter for mealybugs and scale insects. Inspect regularly at the base of rosettes; treat with isopropyl alcohol on a cotton swab or a systemic insecticide if infestation is heavy.
