Water: Euphorbia trigona like to dry out between waterings. Dip your finger about an inch into the soil: if it's damp, you can wait on watering; if it's dry, you know it's time to water again.
Light: Prefers bright light. Direct sunlight is ok but take care to ensure this does not scorch the plant. Water: Allow the soil to dry out before watering. Do not over water.
Provide Euphorbia trigona with a light feeding of balanced water-soluble succulent fertilizer monthly during the spring and summer. Reduce watering and do not fertilize at all during the cooler months (fall and winter).
You needn't worry much about pH level as Euphorbia trigona grow in acidic, neutral or alkaline soil. Water when you plant the cuttings, keep the soil lightly moist until signs of rooting and growth appear.
A warm place throughout the year is fine. But Euphorbia trigona also grows good with a temperate winter rest period at about 15 °C (59 °F). Minimum temperature is 10 °C (50 °F).
Euphorbia trigona, known commonly as the African Milk Tree, is a member of the Euphorbia genus. Members of the Euphorbia genus emit a milky latex that is quite toxic and can irritate the skin and mucous membranes of all animals. This latex can cause redness, swelling, and temporary blindness.
