🏡 African Milk Tree Care
🌞 Lighting Needs
- Thrives in bright, indirect light but can also tolerate full sun.
- Needs at least 4 hours of bright light daily to grow properly.
- If keeping it in direct sun, monitor for signs of sunburn (browning or dry patches).
💡 Tip: If your plant is leaning toward one side, rotate it every few weeks to ensure even growth.
💧 Watering Needs
- Water only when the soil is completely dry (typically every 1-2 weeks in summer, less in winter).
- Use the soak and dry method—water deeply and allow excess water to drain out.
- Overwatering can lead to root rot, especially if the pot lacks drainage.
🚫 Do not mist—high humidity can lead to fungal issues.
💡 Tip: Stick your finger 2 inches into the soil—if it’s dry, it’s time to water. If it’s still moist, wait a few more days.

🌡️ Temperature & Humidity
- Prefers warm temperatures between 65-80°F (18-27°C).
- Cannot tolerate temperatures below 50°F (10°C)—bring it indoors during cold weather.
- Enjoys dry air—no need for misting or extra humidity.
🪴 Soil & Potting
- Use a well-draining, sandy soil mix, such as:
- Cactus/succulent mix or
- A blend of potting soil + sand/perlite for better drainage.
- Ensure the pot has drainage holes to prevent root rot.

🌿 Fertilization
- Feed once a month in spring and summer with a cactus or succulent fertilizer diluted to half strength.
- Do not fertilize in fall and winter, when growth slows down.
✂️ Pruning & Maintenance
- Trim dead or damaged stems with gloves and caution (the sap is toxic and can irritate skin).
- Wipe dust off the stems with a dry cloth to help with photosynthesis.
- If your plant leans too much, stake it or move it to a brighter location for stronger growth.

🌱 Propagation
African Milk Trees are easy to propagate from stem cuttings.
How to propagate:
- Wear gloves and use a clean knife to cut a healthy stem.
- Let the cutting dry for 1-2 days to allow the sap to seal.
- Plant it 1-4 inches deep in dry succulent soil.
- Wait a week before watering to avoid rot.
- New roots should develop in a few weeks!
🚫 Avoid touching the sap—it can cause irritation!
