The house I bought recently was not completely fenced so there were deer in the yard who ate the lower parts of the cedar hedge over many years (see photo). I have now fenced the property so there are no more deer. There is still some green growth on the bottom of the hedge. I am wondering whether the bottom of the hedge will eventually grow out to fill in the gaps. Should I be clipping the upper part of the hedge back to allow more sunlight to reach the lower branches? I know that I can't clip the hedge back too far into the old wood so I'm not sure if a minor clip will do any good. I'm looking for advice.
