Care and Maintenance

Care and Maintenance of African milk tree

Caring for the African Milk Tree Cactus (Euphorbia trigona) is relatively straightforward, making it an excellent choice for both seasoned plant enthusiasts and beginners. Here are detailed care and maintenance guidelines to ensure your African Milk Tree thrives:

Light Requirements

The African Milk Tree prefers bright, indirect sunlight. It can adapt to some direct sunlight but avoid prolonged exposure to prevent scorching its leaves. A spot near a window that receives filtered light is ideal. Rotate the plant occasionally to ensure even growth on all sides.


This plant is drought-tolerant, requiring minimal watering. Allow the soil to dry out completely between watering sessions. Overwatering can lead to root rot, so it’s crucial to ensure proper drainage. In the winter, when the plant’s growth slows down, reduce watering significantly.


The African Milk Tree likes soil that drains water well, so its roots don’t get too wet. A special cactus or succulent potting mix is perfect for it. These mixes usually have ingredients like sand and tiny rocks that let water flow through easily. If you want to make your own mix, just mix some regular potting soil with sand and a bit of perlite or pumice. Also, make sure the pot you use has holes in the bottom so extra water can escape. This keeps your plant happy and healthy, just like in its natural dry home.

Temperature and Humidity

The African Milk Tree thrives in warm conditions and is quite adaptable to average indoor temperatures and humidity levels. It prefers a temperature range of 60°F to 85°F (15°C to 29°C) and should be protected from temperatures below 50°F (10°C) to avoid cold damage. While it doesn’t require high humidity and can handle dry indoor air, it may benefit from occasional misting or a pebble tray to slightly boost humidity in extremely dry environments. However, it’s important to ensure that it’s not exposed to excessive humidity, as this can lead to problems like root rot. With its forgiving nature towards temperature and humidity, the African Milk Tree is a robust and easy-to-maintain choice for indoor gardeners.


Pruning is not usually necessary for the African Milk Tree. However, if you wish to control its size or shape, you can prune it carefully. Always wear gloves when handling the plant to protect yourself from the thorns and the toxic sap.

Handling Sap

Be cautious of the plant’s toxic sap when pruning or repotting. Wear gloves and wash your hands thoroughly after handling the plant. Keep it out of reach of children and pets, as the sap can cause irritation and is harmful if ingested.
