Repotting is done for several reasons: to work on and prune the roots, to change and refresh the soil, and to adjust the planting angle. Sometimes all three. Here are a few examples of each.
First up is a “normal” repotting of a Chinese quince, which is pot-bound. All soil is removed, roots are trimmed back, and heavy roots are removed from underneath the base. The tree is secured back into the same pot, and fresh soil is worked in:
This Ume only needs fresh soil, so very little root pruning is done. A couple dead roots are removed, and thoroughly rake away compacted soil from under the base of the trunk. Then the tree is secured back into the same pot, and fresh soil is worked in:
This itoigawa was restyled last year, and the planting angle was changed significantly. To change the planting angle, it will take several repotting efforts to get the roots on the new horizon.
I have been studying bonsai since 1994, in an ever-increasing obsessive fashion. In our last 5 years prior to moving from Iowa to Alabama pursuing a career in the foodservice industry, my bonsai collection was limited to a few varieties that could survive brutal winters outside, or winters under dim light in the dank basement of our humble duplex...my wife puts up with a lot. Including the trailer hitch I put on our brown 1983 Chrysler New Yorker to pull a U-Haul full of trees to Nashville for a 3-month stop along the career path that led us to Alabama. 12 years later, we no longer have the New Yorker; and not a single one of those trees remain on my bench, having given the last holdout to a new club member this summer. I prefer collecting native trees and buying the classical species used in Japan, feeding organic, and reading everything I can get my hands on.
