Copiapoa krainziana problems — and how to fix them
Copiapoa krainziana (Copiapoa krainziana) 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.
Overwatering and rot
Soft, discoloured or collapsing stems mean the roots have rotted. Use very gritty soil, water only when bone-dry, and keep dry through winter.
Sparse, weak spines
Too little light produces thin spination and pale stretched stems. Maximise direct sun to keep the dense white spine cover that defines this species.
Mealybugs
They nest in the crown wool and dense spines where they are hard to spot. Check regularly and treat with systemic insecticide or alcohol swabs.
Sunburn after a move
Plants raised in shade scorch if suddenly exposed to full sun. Introduce stronger light gradually over a couple of weeks.
