Care Guide for the Euphorbia Trigona
To maintain a healthy Euphorbia trigona, keep the plant preferably in a sunny, dry location where the mininum temperature is around 55°F (12°C). To encourage new growth on the Euphorbia trigona, water once a week during the warm seasons and every two weeks during the cold climates. Always allow the soil to dry out between watering and whenever in doubt about watering, do not water. You can propagate by cuttings. Like all Euphorbias, the "African Milk Tree" will release whitish sap when cut. To stem the flow, place the cut edge under cold running water. Then, spray the cut end on the mother plant with water. Allow the cutting to dry out for a few days to prevent rot. The best time to propagate these plants is during the spring and summer, yet propagation works best when the temperature is about 70°F. When planting these cuttings, be sure to wear heavy leather gloves or wrap the cut stems in several layers of newspaper for handling. Use a small container that is proportionate to the size of the cutting. If the container is too large, the soil may stay moist and lead to rot. After repotting, wait several days before watering.
