How to Use Charcoal in Bonsai Soil
Choose the Right Type of Charcoal:
Use activated carbon or charcoal pellets, as these forms are most effective for soil improvement.
Mixing with Soil:
Incorporate a small amount of charcoal into your bonsai soil mix. Aim for about 5-10% of the total soil volume to start.
Layering:
You can also use charcoal as a layer at the bottom of the pot to enhance drainage and prevent water stagnation.
Regular Maintenance:
Replace the charcoal periodically, as it can become saturated with impurities over time. Doing this annually or biannually is generally sufficient.
By incorporating charcoal into your bonsai soil, you can significantly improve the health and vitality of your bonsai tree, ensuring it thrives for years to come.
