Red Lava Bonsai Soil Component - Medium Grain - 1 Gallon
If you like to mix your own soil, it's good to have some lava on hand. It's is a key ingredient in many, if not most, bonsai soil mixes, including our favorite Pro Mix, which is equal parts lava - pumice - akadama. Or sometimes a mix as simple as lava and pumice works, depending on your climate, type trees and other factors.
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 for Shohin mixes.
