Euphorbia Erytrea requires little pampering, In fact more die from too much care and watering than from neglect. Make sure you give your Euphorbias well-draining soil and lots of sunlight.
Place the euphorbia plant in a location that receives bright, direct sunlight and stays consistently warm.
Unlike most succulents, Euphorbia does not handle long periods of drought well. It may need weekly watering during the summer. Water when completely dried out, drench until water comes out of the bottom then leave to dry again. Water much less in the winter.
Pot in fast draining sand and soil mix with drainage holes at the bottom.
