We live in the northern third of Ohio Last winter all of these plants died. So we got new ones that have done well Should we trim, and then cover? Some sights say woven row cover?.? We do get snow, and many below freezing days We would really like to keep them. We have them along our front walk Would the white styrofome cones work? Thanks Newt
