Thanks for reading for my post. Quick synopsis of my ordeal, I have this circle in my front yard which used to be a hibiscus tree, but unfortunately due to my stupidity I killed it and to add to my problems , my whole front yard is inundated with vole tunnels. The vole has its burrow in that circle. I want to plant something that will not provide ground cover for the voles and also requires the least amount of care. What would you all recommend I can plant there? or would you recommend going a totally different path?
