Black Lava Bonsai Soil Component Medium grain - 1 quart
Lava is what many bonsai pros use as an important component in their soil. One of our favorites is a lava - pumice mix, or a lava - pumice - akadama mix. Most particles range from about 1/4" up to about 1/2" (about 6 to 13mm).
Though you can use it as is, some people choose to sift it. Once sifted you can use larger particles in mixes for large bonsai trees and smaller particles in mixes
for small bonsai. 1 quart bag
