Oak tree, around 37 years old, always in a tray.
Bought it some time ago in Gingko bonsai center.
65cm high, 21cm circumference. Leave size reduced to appr. 1/3 of the normal size.
At this point I'm gonna cut the biggest leaves to 1/3 , to bring light in the tree
Now, that is quality answer Frank! Well done on leaf reduction. Do you say that the tree was planted as an acorn in shallow pot and grown in it since or that it was transplanted into shallow pot 37 years ago?
