Bonsai Drainage Mesh: When You Need It & How to Use It

Watering bonsai is an art—too much or too little kills. Proper drainage is non-negotiable.

The Hole Problem

Every bonsai pot needs drainage holes. Many have oversized holes that leak soil. Solution: drainage mesh.

Choosing & Installing Mesh

• Buy plastic or metal mesh (hardware/garden stores). Small squares covering holes.
• Prefer smaller holes—water still drains, soil stays.
• Held in place by soil weight.

DIY Alternative

Use bonsai wire to form a small loop/coil over the hole. Experiment for fit.

Critical Rule

Never let a bonsai sit in water. Mesh prevents soil loss while maintaining free drainage—the foundation of root health.
