I've just gotten started with camellias and planted my first one in the front yard near some azeales. I have a lot of voles and moles in my front yard. The moles have nearly ruined the lawn, and the voles killed a couple of the large azaleas with their tunnels. It took them two years to completely kill my new little camellia -- two years of circumnavigating the root system (and my replanting) and then two days after the most recent replanting, completely knawing the trunk clear through (looked like an underground beaver at work).

So now I've just brought home a new camellia that I want to plant in the same spot. I also bought "Vole Block", a sharp and crunchy material that you put in the planting hole. Have any of you had similar problems with voles? What did you do? Any other recommendations to deter these critters? Thanks.
