Troubleshooting
Etched Cone Plant problems — and how to fix them
Etched Cone Plant (Conophytum ectypum) 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 dormancy
Never water when the plant is wrapped in its papery sheath; any moisture at this stage invites fungal rot.
Sheath not shedding
In very low humidity the papery sheath may cling; gentle peeling by hand in late summer can help new bodies emerge.
Stretching
Insufficient direct light causes elongation; move to the brightest available spot.
Mealybugs
Check inside the central fissure; treat with isopropyl alcohol on a fine brush.
Sunscorch
Sudden exposure to intense midday sun after a dull spell can bleach or blister leaf bodies; acclimatise gradually.
