Using Ornamental Grasses in Your Landscape. Learn from the Grey County Master Gardeners about the diverse types of ornamental grasses, how to plant and divide them, where to place them and how to use them for best effect in your garden. Grasses are a wonderful attribute in our gardens. They provide texture, movement, and sound. The Gardener in Residence program is presented by the Grey County Master Gardeners. Attend a monthly gardening demo followed by a 1-hour drop-in advice clinic for all your plant and garden queries.
