yesterday I picked up a nice ‘Jacobsen’ mugo. I like it as it is naturally more open and showing more trunk than most mugo pines with a lot less branch whorls. In reading Vance’s recommendations he suggests repotting in mid-may to August. Why in the hot part of the year instead of early spring or fall? I would like to get it into bonsai soil but worry about stressing it during our hot dry weather here in Utah Though currently we are still in the 60’s and 70’s. This one is about 17 inches tall and 1 1/2 inch trunk diameter at the soil. This morning I did a little light pruning and tied one branch down a little with some cotton string
