Okay, admittedly this may seem to be an odd question/topic. This winter, deer ate a 300' row of arborvitae along oneside of our backyard property line...each tree was eaten down to the bare branches from the ground up to a height of about 5 feet...leaving the tops of the shrubs full. One day the shrubs were full...next day...not so full!! We trimmed about 2' off the top of each shrub, hoping it would encourage the bottom of each shrub to "fill in". Will it work? Or, are these shrubs done for? We thought it might be worth a shot...short of digging up the row and replanting...certainly, it was the budget approach at this point. They had been such a nice privacy barrier, too!! Argggh!!! Anything else we might be able to do to encourage the shrubs to fill in? Any similar experiences, advice, etc...greatly appreciated!!!
