I have this line of shrubs (that now look like trees, 10+ ft tall) on my lot line. I was talking to the neighbors who said that the people who lived here a long time ago used to keep them pruned such that they were a 6 ft tall hedge that you couldn't see through. The people who lived here before us for 8 years did nothing to them and now they look like junk. They get no flowers or berries. So! Can anyone tell me what these are and how I might be able prune them back into hedge form? BTW, I am in south central WI.
