Troubleshooting
Yellow Cone Plant problems — and how to fix them
Yellow Cone Plant (Conophytum flavum) 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
Caused by summer watering or poor drainage. Allow soil to be bone dry during June–August.
No flowers
Insufficient direct sunlight is the main cause; move to a brighter spot and ensure flowers can open in full sun.
Sheath retention
If the papery skin does not shed naturally in late summer, gently remove it to allow new bodies to emerge.
Mealybugs
Inspect the fissure and base of the plant; treat with isopropyl alcohol.
Pale or bleached leaf bodies
Caused by sudden overexposure to hot direct sun; acclimatise plants gradually.
