Troubleshooting
Euphorbia persistentifolia problems — and how to fix them
Euphorbia persistentifolia (Euphorbia persistentifolia) 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.
Leaf drop
Although it holds leaves longer than most euphorbias, sudden chill, drought stress or low light still triggers leaf loss. Keep conditions stable and bright.
Root and stem rot
Overwatering, cold wet soil or poor drainage causes soft, blackening stems. Let the mix dry between waterings and cut back hard in winter.
Irritant latex sap
Pruning releases caustic milky latex that irritates skin and eyes. Wear gloves, work carefully, and wash off any contact promptly.
Etiolation in poor light
Stems stretch with wide gaps and weak structure when light is too low. Move to a brighter window or add supplemental lighting.
