Janice, I need to send you my resident red-shouldered hawk for a couple of days. I'm sure he would make quick work of those voles and enjoy doing it.
Here is part of the 130 foot trench I dug for the rubber edging that goes around my new garden. The garden will house a couple of palms, 4 cycads and the cyms in pots. It goes along with my goal of eliminating as much grass as I can. I still need to put down the landscape cloth and cover it all with mulch.
