have been growing bonsai for many years, and i love my trees. embarassed to say that i have never been to an official workshop with a bonsai master. signed up for two coming up. what tree do you take? do you take one that has never been worked on? or one that you just need a professional opinion? the workshop is for 4 hours, if you just need an opinion, what do you do for the rest of the time? i'm kind of lost: any suggestions?
