Great results, nicely presented progression...Side question, your use of Turface? Is this Turface MVP? Straight from bag, or sifted?
Great progression Greg. I'm curious as to what kind of soil you've been growing the trees in though. Up until the last picture or so, the soil looked like plain ol' Miracle-Gro??
Amazing work! Are there limitations to this method? I have a Japanese red maple with reverse taper that I wonder if this will work. Thanks.
