We have moles and voles here that make huge holes. A neighbors horse broke its leg in one so now before I drive my horse I walk my entire trail and scuff the piled dirt back over the holes and tamp it down. We lived in the mountains in a forest before we moved to where we are now so I had never planted a tree before! We purchased vacant land to build on with no shade and planted trees. I didn't know that rabbits would gird the trees! I thought my husband had gotten them with the weed trimmer. Had to start over and I encircled all the trees with wire I had. Veggie garden is fenced now.
