Hedgingmybets... looking great. They look like mine did before the first cut, and after. Hard to believe but all that new light green growth is what will form your hedge. The old shoots are useless now. All they'll do is drop yellow leaves in the years to come. Keep pruning... every stem, every April.
Annual update as promised. Mine have just hit 3yrs since the initial cut. Around 9ft now and still in growing season (ground level is 1ft below the wooden loglap panelling). That's around 2ft per year by my reckoning. Now giving me the screening I wanted. 3yr old pic included for reference for anyone finding this thread.
