Having followed this thread for some time I finally made the plunge; here are three yamadori from this past weekend. Each of these trees were collected in South-Central Utah at approximately 7,500 ft in elevation. Conditions were seemingly ideal given the recent storm of snow and rain.
From left to right:
1) Pinyon Pine collected on a windy mesa. Although rooted in heavy clay, there was a flat rock directly beneath the tree. Sometimes you get lucky I guess
2) Pinyon Pine collected on a small outcropping (see third photo). Somewhat nervous about the percentage of roots recovered as the sand fell away almost entirely, thereby taking the fine roots (with that said I got most of the feeder roots). Fingers crossed.
3) Ponderosa Pine collected in a shallow depression. The root mat was surprisingly thick and necessitated some trimming in order to plant.
Admittedly, I was somewhat uncertain how best to plant these in their respective grow boxes. Some threads recommend cleaning the roots a bit and introducing some bonsai soil in addition to the native soil; whereas others, solely recommend planting with the collected soil and repotting in subsequent years with bonsai soil––I opted for the latter method.
Any age estimates would be greatly appreciated
