Jose,
I am hoping that the trees will fill out in the coming years, so I will not do much pruning exept pinching new shoots( I allready begun doing this).
Mister Crow,
Thanks for sharing these wunderfull pictures ! Of course my group will never reach this level. My boxwoods lack the great movement in the trunks, but I can use this for reference. I tried to mantain a triangular form and I think I succeeded in doing this. Oh well, maybe I should just wait and see how it developes. Patience, patience...
Thanks ! René
