African Milk Tree

African Milk Tree is Euphorbia trigona, a succulent member of the spurge family. Its upright angular stems carry small leaves and paired spines along their edges. [1]

The leaves are short-lived; firm green stems remain the main framework. A few lost leaves do not, by themselves, mean that the whole plant is dying. [2]

Give bright indirect light indoors. For a summer outdoor position, introduce partial sun gradually and watch the newest tissue for scorch. [1]

Keep the whole branching crown well lit. Rotate a manageable pot periodically rather than letting all new growth lean strongly toward one window. [6]

Use a free-draining cactus or succulent mix. Keep drainage holes open and size the container around the roots rather than the eventual height. [2]

A stable pot is important beneath a tall crown. Maintain the stem’s former planting depth instead of burying it for extra support. [11]

Keep African Milk Tree warm and protect it from frost. Bring outdoor containers inside before temperatures fall below 45°F / 7°C. [1]

Ventilate warm rooms and avoid cold, wet conditions. Extra humidity is unnecessary for this succulent-spurge growing approach. [4]

Feed lightly during active growth with a diluted succulent product. Follow its directions and avoid repeated feeding to force rapid height. [9]

Stop when growth slows. If the potting mix includes a slow-release feed, account for that before adding liquid fertilizer. [18]

Prune in early spring only if size or balance needs attention. Support the part being removed and make a clean cut with appropriate protective equipment. [2]

Keep cuttings and sap-contaminated debris away from children and animals. Wash tools and hands after the work. [5]

Retain a bright position through winter, with reduced watering as growth slows. Keep the pot away from cold drafts and avoid a wet root ball during rest. [4]

African Milk Tree resembles a cactus but is a Euphorbia. True cacti have areoles; succulent euphorbias have a different stem structure and irritating milky latex. [4]
