Japanese Bonsai Bottom Square Net - 3 Sizes Available
Keep your substrate secure and maximize root aeration with these authentic, professional-grade bonsai drainage screens. Imported directly from Japan, these heavy-duty plastic drainage mats (園芸鉢底網) are a foundational requirement for clean potting and long-term root health.
Why They Are Essential:
- Zero Substrate Loss: Places perfectly over the primary drainage holes of your ceramic containers. It keeps premium, fast-draining gritty mixes (like Akadama, Pumice, and Lava rock) inside the pot instead of flushing out the bottom.
- Prevents Root Rot: The open-grid geometry allows water to evacuate instantly. It prevents stagnant water pools at the bottom of the pot, encouraging superior oxygen exchange to protect fine feeder roots.
- Ultimate Pest Barrier: Acting as a heavy-duty sub-surface shield, it completely blocks subterranean pests like slugs, worms, and beetles from climbing through drainage holes to feast on your tree’s root system.
- Rigid, Heavy-Gauge Plastic: Unlike soft, flimsy mesh rolls that bow under the weight of wet gravel, these pre-cut rigid squares sit entirely flat and hold their shape permanently under heavy substrates.
- Fully Reusable & UV-Stabilized: Will not rot, rust, or degrade from constant moisture exposure or intense outdoor heat, allowing you to wash and reuse them repotting after repotting.
How to Use:
Place a square directly over the main drainage hole at the bottom of your bonsai pot. Secure it flat against the floor using standard aluminum or copper training wire looped through the grid and out the bottom tie-down holes.
