Dune Grass, also known as American Beachgrass and Marram Grass, is a spreading, rhizomatous native bunch grass common along the shores of Lake Michigan. Dune grass is often used as an erosion control plant for dune stabilization or on non-dune areas where soils are sandy and dry. Dune grass is attractive to many homeowners because it requires minimal maintenance-no mowing necessary, and once established, this native plant requires no irrigation or fertilizer.
Dune grass requires a sunny location and well-drained soils. The best times to plant is in the spring (April/May) and in the fall (September/October).
Stems of plant (culms) should be planted at least 8" deep. One to three culms should be planted per hole and spacing depends on how much erosion protection is needed or desired density.
18 inch spacing: For areas with flat ground and little threat of erosion. One bundle of 500 covers 1,000 square feet.
12 inch spacing: For flat or sloped areas that need some erosion protection. One or two sprigs of dune grass per square foot.
8 inch spacing: For sloped areas with moderate erosion. Two per square foot.
6 inch spacing: For high erosion areas (steep slopes and potential 70 mph winds).
Oceana Conservation District sells dune grass in April and in September.
