What are the drainage requirements for rattan outdoor tree boxes to prevent root rot?

Proper drainage is crucial for rattan outdoor tree boxes to prevent root rot and maintain healthy plants. Here are the key requirements:

1. Drainage Holes: Ensure the tree box has adequate drainage holes at the bottom to allow excess water to escape. At least 4-6 holes are recommended for medium-sized boxes.

2. Elevated Base: Place the tree box on feet or a stand to elevate it slightly, promoting airflow and preventing water from pooling underneath.

3. Well-Draining Soil: Use a high-quality potting mix designed for outdoor containers, incorporating perlite or sand to improve drainage.

4. Layer of Gravel: Add a layer of gravel or small stones at the bottom before adding soil to enhance water flow and prevent clogging of drainage holes.

5. Regular Monitoring: Check soil moisture frequently and avoid overwatering, especially during rainy seasons.

By following these steps, you can ensure your rattan outdoor tree boxes provide optimal conditions for plant health and longevity.
