Troubleshooting
Euphorbia decaryi problems — and how to fix them
Euphorbia decaryi (Euphorbia decaryi) 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.
Stem and root rot
The creeping, partly buried stems rot if the soil stays wet. Use a very gritty mix, let it dry between waterings, and water sparingly in the dormant season.
Leaf scorch
Intense direct sun can burn the crinkled leaves. Provide bright but mostly indirect light and shade from the strongest midday rays.
Leggy growth in low light
Too little light makes the stems stretch and the rosettes sparse. Move to a brighter position to keep the mat dense and compact.
Mealybugs
Pests can lodge in the leaf rosettes and along the stems. Inspect regularly and treat with dilute isopropyl alcohol or a suitable insecticide.
