Black Lava Bonsai Soil Component small grain - 1 gal
Lava is what most pros use as an important component in their soil. One of our favorites is a lava - pumice mix. Another is lava - pumice & akadama mix. Most particles range from about 1/4" down to about 1/8" (about 6 down to 3mm).
Though you can use it as is, some people choose to sift. Once sifted you can use larger particles in mixes for large bonsai trees and smaller particles in mixes
for small bonsai. 1 gallon bag
