Use a fertile, free-draining mix (e.g., potting soil amended with perlite and peat/coconut fiber). Ensure strong drainage (avoid waterlogging) while retaining moderate moisture; a small proportion of fine bark can improve aeration. Use a pot with drainage holes and do not let the rootball sit in water.

Seed propagation is possible but uncommon; sow fresh seed indoors in warmth (about 24–29°C) on a sterile, free-draining medium, cover very lightly, and keep evenly moist with high humidity and bright indirect light. More reliable propagation is by semi-ripe stem cuttings: take 10–15 cm tips, remove lower leaves, allow latex to stop bleeding, and root in a warm, humid environment; pot on when well-rooted. Transplant/repot in spring into a well-drained potting mix and avoid cold drafts.

Feed during active growth (spring through early autumn) with a balanced liquid fertilizer at reduced strength; apply about every 2–4 weeks, flushing the pot occasionally to limit salt buildup. Reduce or stop fertilizing in winter when growth slows; avoid overfeeding, which can cause leaf edge burn and weak growth.

Outdoors in tropical climates, apply a light organic mulch (bark/wood chips) to conserve moisture and reduce root-zone temperature; keep mulch a few centimeters away from stems. For containers, a thin top-dressing (e.g., clay pellets) can reduce evaporation without blocking gas exchange.

Stake container-grown plants if stems become tall or top-heavy; tie loosely with soft ties to avoid bark damage. Use a cane inserted near the main stem and adjust ties as the plant grows.

Pinch or prune shoot tips to promote bushiness; hard-prune leggy stems in spring or early summer to encourage branching. Remove weak or damaged growth. Wear gloves—milky sap can irritate skin.
