Troubleshooting
Engraved Cone Plant problems — and how to fix them
Engraved 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.
Summer rot
Watering during dormancy penetrates the protective sheath and rots the new body developing inside. Absolutely no water from late spring to late summer. If the sheath becomes soggy, remove it carefully and allow the emerging body to dry.
Root mealybugs
Root mealybugs (Rhizoecus spp.) are a serious pest of Conophytum, causing sudden collapse. Tip the pot, inspect roots for white waxy deposits, and treat with systemic insecticide drench. Check at every repotting.
Failure to flower
Insufficient light and incorrect dormancy timing are common causes. Ensure the plant has a true dry, warm summer rest and that watering resumes in late summer with slightly cooler autumn temperatures to trigger flowering.
