Bonsai Soil Grader (3 Piece) – 300mm
Designed for preparing and grading bonsai substrates, the 30cm Bonsai Soil Grader provides a simple and efficient way to separate soil components into consistent particle sizes before repotting or creating custom substrate blends. Supplied with three interchangeable mesh screens, it allows practitioners to remove unwanted fines and separate larger particles to achieve a cleaner, more uniform growing medium.
The three mesh sizes — 2mm, 4.5mm, and 7mm — provide excellent versatility when working with common bonsai substrates such as Akadama, pumice, scoria, Kanuma, and other granular soil components. Correctly grading substrate helps reduce excessive fine material while promoting the drainage, aeration, and consistency required for healthy bonsai root development.
Featuring a durable stainless steel frame and galvanised iron mesh screens, the grader has a generous 30cm diameter suitable for preparing both small quantities and larger batches of substrate. The interchangeable screens can be used individually depending on the desired particle size, making this a practical addition to any bonsai repotting setup.
Suitable for beginners through to experienced practitioners, the Bonsai Soil Grader provides an easy and effective way to prepare substrates for repotting, soil blending, and ongoing bonsai cultivation.
