Japanese beech, Fagus creanta.
Some may wonder why I make the tree so much uglier after it looked quite good already.
Well, most amateurs would never do this, I understand. They want their trees to look their best all the time. So their trees don't really improve a lot. I believe that I can still improve this beech and accept that it will look ugly with these guy wires for one to two years. If I have done the right thing now the tree will be clearly better then. Even award winning show ready trees can be improved and should be. The better is the enemy of the good.
