Troubleshooting
Split Rock problems — and how to fix them
Split Rock (Pleiospilos nelii) 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.
Bloated, splitting, or rotting body
Classic overwatering — the leaves take up too much water and burst or turn mushy; cut watering hard and ensure the mix is fully mineral and fast-draining.
More than two leaf pairs at once
A reliable sign of overwatering or feeding during dormancy; a healthy plant keeps only this year's new pair plus last year's shrivelling pair.
Pale, stretched, or splitting-open growth
Etiolation from insufficient light — move to the brightest possible spot or add a grow light.
Old leaf pair not shrivelling / mushy dormant leaves
Too much water during the rest period stops the natural absorption of the old pair and invites rot; withhold water and let the cycle complete.
Refuses to flower
Usually a missing dormancy — give a cool, nearly dry winter rest with strong light to trigger the daisy-like autumn-to-spring blooms.
Root or basal rot
Standing moisture around the taproot; unpot, trim any black roots, and replant in dry gritty mix in a deep, well-drained pot.
