Birches are great trees to be used as a bonsai. Despite the fact there are a lot of confusions, myths and rumors... Shame on those who say "not worth the effort". I know, It sounds much better than simple "I cannot do it". At least for ones EGO.Thank you, Maros, for keeping the birch flag so high. Very realistic B. pendula.
It is easy if you do what you like and have your own way. Thanks my friend
