Planting and Transplanting Dragon Tree
Choosing the Right Spot
Dragon trees thrive in bright, indirect sunlight but can adapt to lower light conditions. Place it near an east or south-facing window for optimal light. Avoid direct sunlight as it can scorch the leaves.
Planting in the Right Soil
Use a well-draining potting mix, such as one formulated for cacti or succulents. You can also mix standard potting soil with sand or perlite to improve drainage. The key is to prevent water from pooling at the roots, which can cause rot.
Transplanting
Dragon trees need repotting every 2–3 years or when the roots outgrow the pot. Choose a container that is 2 inches larger in diameter than the current pot.
Steps for Transplanting:
- Water the plant a day before repotting to reduce stress.
- Gently remove the plant from its pot, being careful not to damage the roots.
- Place the tree in the new pot, filling around the roots with fresh soil.
- Water thoroughly and allow excess water to drain.
Dragon Tree Care
Caring for a dragon tree is straightforward, but consistency is crucial.
Watering
Dragon trees prefer soil that is evenly moist but not soggy. Water when the top inch of soil feels dry. During winter, reduce watering since growth slows down. Always use a pot with drainage holes to prevent root rot.
Light Requirements
While dragon trees can survive in low light, they thrive in bright, indirect light. Rotate the plant occasionally to ensure even growth.
Temperature and Humidity
Dragon trees prefer temperatures between 65°F and 80°F. Avoid placing them in drafty areas or near heating vents. They also appreciate moderate humidity, so consider misting the leaves or using a humidifier during dry seasons.
Fertilization
Feed your dragon tree with a balanced liquid fertilizer every month during the growing season (spring and summer). Avoid over-fertilizing, as this can lead to brown leaf tips.
