Troubleshooting
Sea Spurge problems — and how to fix them
Sea Spurge (Euphorbia paralias) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root and crown rot in wet conditions
The roots are very sensitive to sustained moisture; in heavy or waterlogged soil, fungal rots (Phytophthora, Pythium) quickly kill the crown. Ensure perfect drainage and avoid overhead watering or mulching against the stems.
Sap contact causing skin and eye burns
Not a pest problem but a serious handling hazard — the latex sap causes severe dermatitis and eye inflammation. Always wear gloves and goggles when pruning, dividing, or removing the plant, and wash hands thoroughly afterwards.
