Now in Winter I can see the progress a years vigorous growth has made to my Quercus cerris. The guy wires will come off for repotting in Spring at this new angle and then go back on until next Winter. Next year I will comission a suitable pot for it (if finances allow).
Some may not like the rangey branches on this tree, but this is really how old oak trees often grow. This is not suposed to look like an idealised tree, but a real tree.
It is partially inspired by this magnificent Sweet Chestnut at Tortworth, one can imagine from this what the bonsai will look like with much more branch ramification. It will take many years of horticulture for this bonsai to reach a mature image.
