It's just ignorance, since my trees are more healthy than natural ones, one of my Bahuinas, is already flowering, and it's just a year old seedling (even younger) while Bahuinas in nature take up to almost 3 or 5 years to flower, I believe that a tree in the nature won't get folliar and soil fertilizer EVER, but our trees are well feed, and well treated. I was talking with a friend once, and he told me, that my trees looked happy, since their colors are better than the ones in the streets, they get their water and their food on time, and I told him that some people like this man said we were cruel or whatever, and he told me, "Trees don't feel, so their reaction to bad situations is fighting, if they don't make it they die, so if they are alive and look better than other trees, then they are doing great" And he is not a bonsai enthusiast, he only have seen my trees, and had a proof just enough to tell that we were not cruel.
What I meant is: As long as he stays closed to bonsai, he won't change his mind, because, he has to know how we treat them to be entitled to talk, or at least watch some of the World's real amazing trees, which are in pots...
Because without considering some bonsai in his books, he is just missing some of the really more amazing trees. Since I've never seen somebody wonder on a natural tree, but I've seen my friends and relatives impressed with some of your bonsai
so let's just don't pay attention to him... Although his book can be a really good source of inspiration for us
So, even if he doesn't want he is helping to Bonsai World!!!
