Troubleshooting
Euphorbia ferox problems — and how to fix them
Euphorbia ferox (Euphorbia ferox) 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.
Basal rot
Wet, poorly draining soil rots the clustering stem bases. Water only when fully dry, use a sharply draining mix, and keep nearly dry in winter.
Soft, stretched growth
Low light produces pale, elongated stems with weaker spines. Provide full direct sun or strong supplemental lighting.
Mealybugs
Hide deep among the dense spines and ribs. Treat with 70% isopropyl alcohol on a swab and re-inspect, as the spine cover makes them easy to miss.
Spine and sap hazard
The stout spines injure and the cut latex is caustic. Wear thick gloves and eye protection when handling, repotting, or pruning.
