Why is My African Milk Tree Turning Brown or Soft?

If your African Milk Tree (Euphorbia trigona) is turning brown or soft, it’s crucial to address the issue promptly to ensure the health of your beautiful plant.

First, consider the watering habits. Overwatering is one of the primary reasons that lead to browning or softening of the stems. This species, being a succulent, stores water in its stems and prefers to dry out between waterings. Make sure you're allowing the top 1-2 inches of soil to dry before watering again. If you notice that the soil remains excessively moist, you may need to repot your plant with fresh, well-draining soil to help promote better drainage.

Additionally, check for signs of rot. If the stems feel mushy and have a brownish hue, it could indicate stem rot caused by overwatering or poor drainage. In such cases, you may need to carefully remove the affected parts and let the plant dry out before repotting. You can also dust off the cut edges with rooting hormone and allow them to callus before replanting them in the soil.

Another factor to consider is light conditions. African Milk Trees thrive in direct sunlight to partial shade. If they are not receiving enough light, they may weaken and develop soft stems. Moving your plant to a brighter location can help bolster its health.

If you suspect pest infestation, regularly inspect your plant for any signs of pests such as mealybugs or spider mites, which can also contribute to stress and deterioration. Treat any infestations promptly with insecticidal soap or neem oil.

Lastly, ensure your African Milk Tree is not exposed to cold drafts or extreme temperature fluctuations. This plant prefers stable environments with warmth. Keeping it in a well-lit room at a consistent temperature will help prevent further issues.

By addressing these factors, your African Milk Tree should rebound and thrive. For more detailed care instructions, check out our African Milk Tree care guide for comprehensive advice!
