Bonsai Tree Size:
This Ponderosa Pine was field collected with permission (yamadori) from Devil’s Tower area of Wyoming at 8-10,000 feet by renowned bosai artist Dan Robinson. Yamadori literally means collecting plants in the mountains. For this tree, the process took 3 years. The first year, a third of the roots were dug up and re-packed. The second year, another third was dug and repacked. The third year, the entire tree was extracted. It was donated in memory of John Carroll in 2002. It was styled by Mauro Stemberger, Italian Bonsai Master, on November 15, 2015.
It is an informal upright style. The pot is large, rectangular, unglazed, brown in color and is 10 inches deep.
They grow from British Columbia southward and eastward through 16 western U.S. states and have been successfully introduced in temperate regions of Europe, and New Zealand.
Q. What do “circa” and “in training” mean?
A. The circa date is roughly the year when the tree sprouted from its seed. The in training date is the year that it started being “trained” as a bonsai, which is to direct the growth of the tree usually by bending, pruning, and wiring its branches into a desired direction or shape.
These trees can be susceptible to red spider mites, needle cast, scale, and white fly. Treat with insecticide (malathion). For needle cast, use fungicide (daconil).
