What we liked

  • + Listed as pure natural red clay from Ibaraki Prefecture, with no binders, fillers or additives, which suits a classic bonsai mix.
  • + Small 3-6 mm grain fits shallow bonsai pots and small trees, and is described as giving steady aeration and drainage.
  • + Air-dried in greenhouses for hardness, and the listing says sun-drying for 2-3 days before use can harden it further.

Trade-offs

  • - Only 2 lb in the bag, so larger repotting jobs will need several bags or a bigger pack of akadama.
  • - Hardness is described as varying with the season, so grain durability may differ from bag to bag.
