The Easy-To-Grow Native Grass That Controls Erosion In Sloped Yards

From dangerous mowing conditions to significant erosion problems, sloped yards are challenging for homeowners. The erosion risk increases with the steepness of the slope. New construction and natural disasters such as floods that disturb the landscape also exacerbate erosion. And on slopes without vegetation, up to 70% of rainwater runs off, while slopes with plants and trees experience only abound 20% runoff. That's just one reason that planting on slopes is a solid strategy for fighting erosion, especially when the use of plants and trees to reduce soil erosion also beautifies your yard. A delightful native grass, side oats grama (Bouteloua curtipendula), is a terrific option for erosion control.

Penetrating, 4-foot taproots and rhizomes spreading 1.5 feet anchor side oats grama to the soil, making it a champ for controlling erosion, especially when combined with other grasses and plants. These powerful, fibrous roots hold the soil in place and help stabilize it. In fact, side oats grama is sod-forming, meaning rhizomes extend horizontally to form solid sod, further controlling erosion. Here's how to incorporate it into your landscaping.

Planting side oats grama—or any plant—on a slope takes special care, and it pays to know a few tips for gardening on a slope. Steepness planting considerations begin at a 20%, meaning the land rises one foot for every five feet of lateral distance. Slopes beyond 50% can't often support plant growth. Low-maintenance plants such as side oats grama are also ideal for slopes, because you can avoid trekking up and down the slope to tend to it.

Side oats grama is hardy in USDA Hardiness zones 3 through 8, and is extremely cold-tolerant. You can grow it from seed or potted nursery plants, which are preferred if you want to arrange the grass in specific locations. It germinates in about seven days and is known for vigorous seedlings. If you don't have a full-sun spot for the plants, they will tolerate partial shade. Side oats grama needs watering only once a month and should not be overwatered. Plant with other grasses and plants for optimal erosion control. Here are four native ornamental grasses you should consider for your yard.

Side oats grama tolerates just about every negative condition imaginable including poor soil that's sandy and clayey and severe weather conditions such as heat, cold, and drought. It is also deer-resistant, and supports wildlife by providing seed for birds, forage for grazing animals, and cover for small critters. It acts as a host plant for the caterpillars of several butterfly varieties. You'll be charmed by the unique appearance of side oats grama; its arching seed stalks feature small, tightly packed spikes hanging uniformly along one side. This dangling display gets colorful when the plant flowers with orange anthers coupled with its blue-green leaves.
