Last weekend we hosted another Shibui field grown tree dig.
A few friends came and helped get the trees dug from the growing beds so I could prune roots and tops then assess them to see which are ready to go into pots for sale and which would be better back in the ground for another season of development. As well as working we had time to assess and refine a couple of trees I have in training. Thanks to Joe and Matt for the help again this year.

After a couple of years these constantly growing roots have so filled the spaces in the potting mix that vital air and water cannot enter the mix and the tree will not stay healthy. It is very important to repot bonsai (and indeed, all potted plants) regularly to keep them healthy. Root pruning does not keep a bonsai small. In fact just the opposite. After rootpruning and repotting in fresh mix with new nutrients and room for new roots to grow we usually see an explosion of growth for the first year.
