Repotting a big trident maple bonsai

It is springtime. So time to repot your trees.

All trees? No. Not all trees. Repot with a reason! One reason could be that the tree has been in the pot so long, that it is filled with roots. Or, as in the case of this trident, because you are working on building a good nebari. Then more frequent repotting can help build the base you are looking for.

Tell me what you think!
