Troubleshooting
Sea Urchin Copiapoa problems — and how to fix them
Sea Urchin Copiapoa (Copiapoa echinoides) 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.
Root and basal rot
Fatal if neglected; caused by excessive soil moisture. Maintain extremely infrequent watering and ensure rapid drainage.
Loss of waxy body colour
The distinctive grey-white waxy bloom can be partially removed by handling or water splashing on the body. Handle only at the pot and water at soil level.
Mealybugs
Inspect the crown and at spine bases. Treat with isopropyl alcohol dabs and a low concentration neem oil drench around the roots.
Very slow growth
Normal for this species; growth rates of a few millimetres per year are typical and do not indicate a problem.
Sunburn from abrupt transitions
If moved from a low-light winter position directly into intense summer sun, pale corky patches can form. Acclimate gradually over 2 weeks.
