Back in May I air layered 3 American elm trees and I am now about ready to separate the air layer and plant into a growing box. I was planning on using my regular bonsai soil mix for the growing medium (1/4 haydite, 1/4 turface, 1/4 crushed lava rock, 1/4 pine bark). Any other suggestions or something I should know about. This is my first time doing this. Thanks!
