Vole repellant expansion
I was reading about a recipe to keep voles from killing plants that was mentioned in the "fall cleanup" thread, and I thought it deserved more attention. I haven't lost any plants that I know of, but I have dug down near the base of some plants to find extensive holes or tunnels. The recipe called for one TBLS of castor oil, and one cup human urine in one gallon of water. This mixture was sprinkled near the roots of susceptible plants. Apparently, the castor oil is quite sticky. I wonder if adding a bit of dish soap would make it easier to work with. Any ideas? Do you think that would decrease its effectiveness?
