Only two moles really did a number on my yard, last summer. I wouldn't care about mole holes in the yard if they didn't uproot my plants. Even worse, they will dig around the roots without disturbing the soil. The plant starts dying from lack of water, but the surface soil is moist. It's not until I step on the soil around the plant that I discover the problem, and the plant drops 4-5 inches lower in the ground.
