I like hostas, but I got tired of them spreading and taking over the whole garden. So I cut all the plants, including the roots, down to the size I wanted using a spade. Then I cut some 12-in. lengths of 8-in. diameter galvanized duct, and drove them into the ground around each plant. It works great to keep the plant from spreading. \u2014 Tom DvorakCheck out these amazing plants to spice up your shade garden.
