At the end of the first year, the tree is usually transplanted from its training pot (or from the ground) into a pot suitable to its dimensions. Retain some of the original soil, and trim the roots if necessary. Cut away any abundant growth of new roots at the base of the trunk before repotting. If only a few roots have formed around the taproot, prune these roots slightly. Prune the taproot again at the end of the second year, and cut it short at the end if the third year. This final cutting should be done when the new roots have appeared at the base.
