How to design fabric overflow reservoirs in self-watering outdoor tree boxes?

Designing fabric overflow reservoirs for self-watering outdoor tree boxes is an effective way to ensure proper water management and prevent root rot. Here’s a step-by-step guide:

1. Choose the Right Fabric: Use permeable, durable fabric like geotextile to allow excess water to escape while retaining soil.

2. Measure and Cut: Size the fabric to fit the base and sides of the tree box, leaving extra for seams.

3. Create a Reservoir Layer: Place the fabric between the soil and a perforated plastic sheet to form a water-holding layer.

4. Install Overflow Channels: Add small gaps or tubes at the sides to let excess water drain out, preventing waterlogging.

5. Test and Adjust: Fill the reservoir and observe drainage, adjusting fabric placement as needed.

This simple DIY solution enhances plant health by maintaining optimal moisture levels in self-watering systems.
