Lord Mugo
I think this 800 mile gap in latitude may have some say so in the future of this tree. Your on par with mid Oregon, we are 200 miles from Death Valley. I know hundreds of bonsai people in the American west and North west, I have yet to see a mugo in an exhibit or a collection. I don't know why. Maybe out here there is not much affinity for the species when Black Pines are so easy to come by and with good bonsai traits for less money.
I also am not sure on repotting in summer here when temps are 106 today, 109 for Tuesday, and an average of 104 for the last three weeks in a row. I am sure you can't treat these as an olive or pomegranite here can you?
If the Mugo can be grown in a landscape it can be grown as a bonsai. I believe that most people that attempt to grow a Mugo try to apply JBP technique and in doing so kiill the tree. I don't know many (read that as any) people even here in Michigan that can grow them because----- they try to grow them with JBP technique. When people come to me they will admit at some point trying to do the JBP thing to their Mugo and state clearly that's what they are doing-----just like they are supposed to with a ------ya' know-----two needle Pine. Isn't that what I'm supposed to do with Two-Needle Pines? People just don't seem to get it. They will tell me how impressed they are with my Mugos but forget almost everything I have been telling them about the tree. Well thankfully we have a few making the effort and we are starting to see some successes-----I hope.
I guess the best thing I can tell people at this point is this: If you are serious in growing a Mugo Pine Bonsai think of the tree as a totally alien species and don't treat it like anything anyone who does not have one tells you to do with it.
