These plants are about 9 years old now and obviously haven't grown well since we laid the driveway. I want the privacy so haven't pruned them yet this year as they are very thin. I've tried to feed them throughout the summer with fish and bone meal and tomato feed too.
Any advice on what I should do? Should I cut them down a bit more so they can fill out and if so, is it too late to do it now? Thanks
