1 quart bag. Also available in 5 & 10 quart bag sizes. Calcined clay is an essential soil amendment for bonsai trees. It's basically like ground up bricks. Fired at over 1200 degrees, the clay becomes rock hard. It will remain the same for years, used as an alternative to sand as most sand is too fine. Do not confuse this with cat litter or Turface! Calcined clay will help your trees develop a fine root system and provide oxygenation.
