Troubleshooting
Euphorbia ingens problems — and how to fix them
Euphorbia ingens (Euphorbia ingens) 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.
Severe sap burns
The abundant latex can cause painful skin blistering and serious eye injury. Always wear gloves and eye protection, work in ventilation, and wash off any contact immediately.
Stem rot and corking
Overwatering causes soft, browning rot, while older lower stems may naturally cork brown. Water sparingly, keep dry in winter, and ensure excellent drainage.
Toppling and weak growth
In low light tall stems grow weak and lean, and large plants become top-heavy. Provide strong light and a heavy, stable pot, repotting only when needed.
Mealybugs and scale
Sap-sucking pests cluster in stem grooves and branch junctions. Wipe off with alcohol and treat with insecticidal soap or a systemic, taking care with the toxic sap.
