The African milk tree, also known as milk bush, euphorbia trigona, or trigona rubra, is a popular succulent plant prized for its striking appearance. This tree-like plant boasts a shallow root system and thrives in full sun, making it ideal for indoor and outdoor settings. While it can tolerate partial shade, optimal growth occurs with direct sunlight.
As a succulent, the milk tree stores water in its stems, so allowing the soil to dry completely between waterings is crucial. This low-maintenance plant, often gifted as a friendship or cathedral cactus, features vibrant green leaves and produces a milky sap when damaged.
Exercise caution when handling this sap, which can be irritating. With proper care, including well-draining soil and moderate watering during the growing season, the African milk tree, a symbol of resilience and beauty, will grace your home or garden for years to come.
Physical Characteristics
The African milk tree boasts triangular stems adorned with small thorns and teardrop-shaped leaves. Its unique structure gives it a distinct, almost architectural look, making it a popular choice for indoor and outdoor gardening enthusiasts.
Growth Habits and Size
The African milk tree can soar up to 9 feet tall when planted outdoors. Indoors, it usually reaches around 4-5 feet, making it a manageable yet impressive houseplant. Its upright growth habit means it won’t take up too much floor space, but it will certainly draw the eye upwards.
Toxicity to Humans and Pets
It’s essential to note that the African milk tree is toxic. The milky sap can cause skin irritation and is harmful if ingested by humans or pets. Always handle it with care and keep it out of reach of curious children and animals.
Care Requirements
Light
The African milk tree thrives in bright, indirect sunlight. While it can handle some direct sunlight, too much can cause sunburn. It’s perfect for a sunny windowsill or a well-lit spot in your garden.
Soil
Good drainage is crucial for the health of your African milk tree. Use a well-draining soil mix, ideally one designed for succulents or cacti. The soil should be slightly acidic to neutral, with a pH level between 6.0 and 7.5.
Watering
This plant is drought-tolerant, which means it prefers to dry out between waterings. For indoor plants, water every 2-3 weeks, allowing the soil to dry completely. Outdoor plants may need more frequent watering, especially in hot climates, but always ensure the soil is dry before the next watering.
Temperature and Humidity
African milk trees prefer warmer temperatures, ideally between 65°F and 80°F. They can tolerate temperatures as low as 50°F but should be protected from frost. They do well in typical indoor humidity levels and can handle dry air, making them suitable for most indoor environments.
Fertilization
Feeding Schedule
Feed your African milk tree during the growing season, typically spring and summer. A balanced, water-soluble fertilizer diluted to half strength works well. Feed once a month to encourage healthy growth.
Type of Fertilizer
Choose a fertilizer formulated for succulents and cacti. These usually have the right balance of nutrients to support your African milk tree without overloading it with unnecessary chemicals.
Pruning and Maintenance
Importance of Pruning
Pruning is essential to maintain the stability and shape of your African milk tree. It helps prevent the plant from becoming top-heavy and falling over.
How to Prune Safely and Effectively
Wear gloves to protect your hands from the sap. Use a sharp, clean knife or pruning shears to remove unwanted branches. Always make your cuts at a slight angle to prevent water from pooling on the cut surface.
Propagation
Methods of Propagation
The African milk tree is easy to propagate from cuttings. Cut a healthy branch and let it dry for a few days to form a callus. Then, plant it in well-draining soil and water sparingly until new growth appears.
Safety Precautions
Due to the plant’s toxicity, always wear gloves when handling cuttings. Avoid touching your face, and wash your hands thoroughly after working with the plant.
Potting and Repotting
Best Practices for Potting
Choose a pot with drainage holes to prevent water from sitting at the bottom and causing root rot. Use a succulent or cactus soil mix for the best results.
Repotting Frequency and Techniques
Repot your African milk tree every 2-3 years or when it outgrows its current pot. Gently remove the plant from its pot, shake off excess soil, and place it in a new pot with fresh soil. Water lightly to help it settle.
Pest and Disease Management
Common Pests
Mealybugs are a common pest for the African milk tree. They appear as small, white, cotton-like masses on the plant. To treat, wipe the affected areas with a cotton swab dipped in rubbing alcohol.
Signs of Overwatering and Related Diseases
Overwatering can lead to root rot and fungal infections. Signs include yellowing leaves, mushy stems, and a foul smell. If you notice these symptoms, reduce watering and allow the soil to dry out completely.
Common Problems and Solutions
Yellowing Leaves
Yellowing leaves can be a sign of overwatering, poor drainage, or insufficient light. Adjust your care routine to address these issues. Ensure the plant receives enough light and that the soil drains well.
Preventative Measures and Remedies
Regularly inspect your plant for signs of pests or disease. Maintain proper watering practices and provide adequate light to keep your African milk tree healthy and vibrant.
