# Best Bonsai Repotting Supplies Source: https://bonsainest.com/best/best-bonsai-repotting-supplies Updated: 2026-09-14 Publisher: Bonsai Nest. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://bonsainest.com/how-we-research#our-score A repot is a soil decision plus a few minutes of cutting, and the soil half is settled almost entirely by particle size and hardness. Aggregates are sold by grain: three to six millimetres for small pots and shallow trays, around a quarter inch for anything with depth, and mixing grades carelessly is how you end up with a pot that stays wet in the middle and dries at the rim. Hard fired akadama holds its structure for a couple of seasons before it slumps, while soft grades collapse into clay within one, so the wording on the bag matters more than the region it came from. Pumice and lava do the opposite job, staying dimensionally stable indefinitely, with pumice holding water inside its pores and lava mostly holding air, which is why the ratio between the three is how a mix gets tuned to a species instead of replaced. Sieving stops being optional once you buy in volume, and a stack of interchangeable screens at one, three, six and nine millimetres separates out the dust that would otherwise clog a pot. On the hardware side, rigid two inch drainage screens stay flat where soft netting curls, anchor wire in the one to three millimetre range ties a root ball down so it cannot rock, and root shears around one hundred ninety to two hundred fifteen millimetres give leverage to cut a woody root cleanly rather than crush it. ## Picks ### 1.
