OK I didnt really get the answer I needed from my searching and numerous books so here you go. I planted 29 Blue Girl and 1 Blue Boy last year. The plants are young, maybe only 2-3 years if not younger. They were kinda rangey since they hadn't ever been trimmed. They were planted with the intention of creating a formal privacy hedge. The owner called me a little while ago and wanted them pruned to make sure they take the proper shape in the future. Nice to see that someone actually cares about there plants. So anyways I get the whole 1/3-1/2 pruning thing, but is there anything I should do to make sure that they will start growing as we intend. They are 4-5ft apart if I remember correctly, they should be about 30" tall and maybe 18" wide. Intended to grow about 5-6' high and eventually create one large wall of shrub. Should I prune all the way around, front and back, or select limbs, or what? This was a good client in a high dollar neighbor hood so I want to get it right. Thanks for any help.
