I was first exposed to the art of bonsai by two gentleman. Mr. Myagi needs no introduction and the second was my BFF's father. Ty who would become a great friend, mentor and "father" to me in time, first learned of bonsai while studying karate at a Japanese dojo during the 1960's. His method of avoiding becoming involved in The Viet Nam Conflict was successful, productive and a "treasure trove" of great stories of adventure.
These men gave me my initial bonsai lessons somewhat concurrently when I was around 12 or 13 years of age. The first tree I killed, was my first tree that had its place of honor atop the TV set in the living room.
IMO no "SERIOUS" bonsai enthusiast has failed to commit "juni-cide" or something approximating this.
The degree to which I've been involved with this amazing and vastly rewarding artform ( I hope it continues to produce unexpected moments of joy and wonder for me, as this tree has done. ) has waxed and waned over the past 38 years but never have I not been involved in some way.
Sorry to wax philosophical but your erroneous assumption provoked contemplative thoughts. Perhaps due to my completing 50 laps around the Big Bright Light this past weekend... I do agree with much of your insight regarding ERCs. Tomorrow the little guy will come home with me. As the needles are neither dry/ brittle or easily pulled loose there is a sliver of hope...
Thanks for contributing my friend.
