I'm looking for some advice. I have a cedar hedge that I neglected to prune last year and now it's way too big. If I cut it back beyond the green ends and thereby get rid of all or almost all of the needles, will it grow back over time? I'd like to cut it way back to get it back under control. I realize it will look bad for a while (does anybody have an idea how long?) but I'm willing to accept that. Thanks.
