Well, I got a chance to see them at this tree farm not far from my house. I had told my neighbor about this tree farm selling 18ft trees for 150 dollars (he wants INSTANT trees)so he went up there to buy them since it was the last day for $150 dollars trees before they increase price to $450. The next day, my neighbor asked me to ride with him so I went there. Not bad. It was your "backyard nursery" type but it's a huge backyard. Lol. The owners lives by them and the area around it is a pasture land for their cows. I'm very impressed how they even knew about Rootmaker, Inc. I think that's their "retirement" job. Something to do. Lol.

Anyway, I am convinced that in ground knit fabric for large trees is the best way to grow large trees while developing superior root system. You get so much more fibrous root system than ordinary B&B that would lead to much faster root establishment without any problems that you'd see in conventional large containers.

Surprisingly, it was pretty easy moving 18ft trees with small root system (18 or 24 inches wide). Probably around 200 lbs. Typically, with ordinary B&B, it'd be 600,800 lbs. Who knows for 200g containers for that size that I've seen a couple weeks ago. No way we'd be able to move them without any machines...
