FAQs
What is Kyodama soil made of?
Kyodama is a type of volcanic clay that is fired at high temperatures, resulting in a hard, porous granule.
Can I use Kyodama for all bonsai species?
Yes, Kyodama is versatile and can be used for most bonsai species, often mixed with other substrates to tailor the soil to specific needs.
How does Kyodama help with drainage and water retention?
Its coarse, gritty nature allows water to pass through easily, preventing root rot, while its porous structure absorbs and holds water like a sponge.
Does Kyodama break down over time?
No, Kyodama is a highly durable material that does not break down, meaning its structure and performance remain consistent.
How much Kyodama should I use in my bonsai mix?
This depends on the species and climate. A common ratio is 50% Kyodama with 50% other substrates, but adjustments can be made based on plant requirements.
Can Kyodama be used as a top dressing?
Yes, it is often used as a top dressing for its aesthetic appeal and to help retain moisture while allowing surface evaporation.
Troubleshooting
Soil appears too dry
Ensure even watering and consider mixing with a more water-retentive substrate if used alone for thirsty species.
Excessive waterlogging
Increase the proportion of Kyodama in the mix or ensure adequate drainage holes in the pot.
Dust during application
Rinse the Kyodama thoroughly before adding it to the pot or mixing with other soils.

Setup, Compatibility & Care Instructions
Kyodama is ready to use straight from the bag. For repotting, it can be used as a component in a custom soil mix or as a top layer. When mixing, aim for a ratio that suits your specific tree species and climate. A common starting point is 50% Kyodama with 50% of another substrate like Akadama. Before use, it can be beneficial to rinse the material to remove fine dust, especially if using it as a top dressing. Store unused Kyodama in a dry place to maintain its structure. No special care is required beyond its incorporation into your bonsai's potting medium; its durability means it does not degrade or require replacement due to breakdown.
