Vole protection? I'm in. Last winter the voles chewed the roots off of my Nanidina hedge. I was so up set, I was only able to salvage 5 of 10 and 1 left in the ground. I wonder if onions or alliums would be as effective as cages. What's to stop them from coming up and over the cages? I started planting onions around my wife's roses and they did great the first year, by the second year she was onboard with the idea, and ordered more ornamental alliums.
