Comprehensive Care Guide for Your African Milk Tree

Light Requirements

Thrives in bright, indirect sunlight but can tolerate some direct sunlight. Too much direct sun can scorch the leaves, whereas too little light may stunt growth.

Watering Requirements

Water sparingly, allowing the soil to dry out completely between waterings. Overwatering can cause root rot, especially in cooler months.

Humidity & Temperature

Prefers warm temperatures (65°F to 80°F or 18°C to 27°C) and low to moderate humidity. Avoid temperatures below 50°F (10°C) as it can damage the plant.


Fertilize lightly during the growing season with a diluted cactus or succulent fertilizer. Avoid fertilizing in winter when growth slows.


Repot every 2-3 years in spring using a well-draining cactus or succulent mix. Choose a pot only slightly larger than the current one to prevent overwatering issues.

Common Problems & Solutions

  • Root Rot: Caused by overwatering. Ensure the pot has good drainage and let the soil dry out between waterings.
  • Yellowing Leaves: A sign of too much water or not enough light. Adjust care accordingly.
  • Pests: Susceptible to mealybugs and spider mites. Treat with insecticidal soap or neem oil at the first sign of infestation.


Can be propagated from cuttings. Use gloves to protect your skin from the sap and allow the cutting to callous over for a few days before planting in well-draining soil.

Pet Safety

The sap of the African Milk Tree is toxic to both humans and pets if ingested and can cause skin irritation on contact. Handle with care and keep out of reach of children and pets.
