The rain stopped late afternoon, so I got after it. I had to quit because it got too dark, and I couldn't see. In about an hour and a half, I left with about 12 small stumps. The largest is maybe a five-inch diameter. I left seven that were too big for me to load up. I will get some help and get them later. I will spray off the native soil, and chain saw the bottoms flat. Maybe try a couple of them upside down, like in the Tom Vuong video Bonsai Nut posted above.
For now, they are going just on the ground. I plan on putting them all in a row on top of weed fabric with a 5" raised bed, with dicing cables in the bottom for a bit of warmth. Cover them up with hoops and plastic, kind of like a large cold frame. What is something
cheap they can be planted in? If they are not in a pot, just in these raised beds, can I use potting soil?
