Native grasses are a practical solution for managing soil erosion and stormwater runoff in Maryland. Their deep roots stabilize soil while improving drainage and supporting local wildlife. Here’s what you need to know:

• Why It Matters: Erosion damages property, clogs waterways, and harms ecosystems like the Chesapeake Bay.
• Top Choices: Switchgrass, little bluestem, and river oats excel in various soil types and conditions.
• Cost Advantage: Over 20 years, native grasses cost around $3,000 per acre, far less than non-native turf grasses at $20,000 per acre.
• Planting Tips: Assess soil, slope, and sunlight. Prepare the site by removing weeds, testing soil, and choosing the right planting method (seeds or plugs).
• Maintenance: Regular care like watering, mulching, and weed control ensures long-term success.

Native grasses not only protect your landscape but also create habitats for pollinators and birds. For tailored solutions, consider professional services to address your property’s specific needs.

Switchgrass planting for wildlife cover and erosion control

Top Native Grasses for Erosion Control in Maryland

Maryland’s diverse soils call for native grasses that can effectively combat erosion. Below are three standout options, along with their benefits and planting tips.

Switchgrass (Panicum virgatum)

Switchgrass is a powerhouse when it comes to erosion control, thanks to its deep root system that extends 5–6 feet into the ground. This underground network helps stabilize slopes, even during heavy storms^[3]. Its versatility is unmatched – it thrives in both drought conditions and waterlogged areas, making it ideal for regions prone to seasonal flooding or dry spells^[3]. Plus, it gets a head start on the growing season, with active growth beginning in April as the soil warms up^[5].

Switchgrass is a great choice for rain gardens and can even grow under black walnut trees, where many plants struggle^[3]. In nutrient-rich soils or partially shaded areas, the grass may grow so vigorously that clumps need staking for support^[3]. Before planting, it’s wise to test your soil and add phosphorus and potassium if necessary, but hold off on applying nitrogen until the seedlings reach at least 4 inches tall^[7]. Keep in mind that switchgrass can spread quickly through self-seeding in the right conditions, making it a strong alternative to invasive species like Chinese silvergrass^[3].

Little Bluestem (Schizachyrium scoparium)

Little bluestem is a standout for poor, dry soils and thrives in full sun, making it perfect for Maryland’s upland areas^[4]. Its ability to perform well in well-drained, low-moisture environments makes it a reliable option for stabilizing spaces like driveways, walkways, and property edges. For challenging upland sites, little bluestem is a dependable choice^[2].

River Oats (Chasmanthium latifolium)

River oats excel in areas with average to wet soils and can tolerate more shade than many other native grasses^[6]. This makes it an excellent option for streambanks, drainage zones, and other moist, shaded areas.

"Using native plants for erosion control is an excellent biological method to help protect the landscape from erosive forces. Native grasses and sedges are particularly effective due to their fibrous roots that grab and hold the soil, keeping it from washing away." – U.S. National Park Service^[8]

To tackle erosion effectively, choose a mix of grasses that match your site’s conditions. Switchgrass is great for wet or steep areas, little bluestem shines in dry, challenging spots, and river oats thrive in shaded, moist locations. By tailoring your selection to the environment, you can set up a strong foundation for erosion control across Maryland.

Preparing Your Site for Planting Native Grasses

Getting your site ready is a key step in ensuring native grasses grow strong and provide lasting erosion control.

Site Assessment

Start by walking around your property to evaluate four main factors: slope, soil type, drainage, and sun exposure. These factors will help you choose the right native grass species and plan your planting approach.

• Slope: Measure the steepness of your slopes. Steeper areas benefit from grasses with deep, sturdy roots, while gentler slopes can support a broader range of species. You can use a clinometer app or a simple rise-over-run calculation to estimate the slope.
• Soil Type: Examine the texture and composition of your soil. Sandy soils, which drain quickly, may suit species like little bluestem, while clay-heavy soils retain moisture and support different grasses. Watch for hardpan or rocky layers that could block root growth.
• Drainage: Look for areas where water pools or flows rapidly after rain. This will guide you in placing grass species that match the drainage conditions of each zone.
• Sunlight: Observe how much sunlight different areas receive throughout the day. Most erosion-control grasses thrive in full sun, so identifying shaded or partially shaded spots is essential.

This assessment will shape your next steps in soil preparation.

Soil Preparation

Getting the soil ready is essential for establishing native warm-season grasses (NWSGs).

"Remove existing vegetation, especially invasive species, to give NWSGs a clean slate." – Joe Brown ^[2]

Start by removing weeds and other vegetation that could compete with your grasses. Follow up with a soil test to check pH and nutrient levels, and adjust as needed ^[2]. You can get soil test kits from your local Maryland extension office.

In small areas, consider removing turf and topsoil to eliminate weed seeds. Although it might seem counterproductive, native meadow plants often thrive in the less fertile soil found beneath the top layer ^[9].

Address drainage issues by filling in deep ruts or holes where water might collect and cause root rot. For persistently wet areas, installing French drains or creating shallow swales can help redirect water.

Finally, lightly till the soil to create a proper seedbed. Keep tilling shallow – no deeper than 2–3 inches – to avoid disturbing dormant weed seeds. Make sure the soil isn’t wet when you work it, as this can lead to compaction ^[12].

Once your soil is ready, timing your planting is the next step.

Best Planting Times in Maryland

Maryland’s location in a transition zone provides some flexibility in planting schedules, but timing is still critical for success.

• Fall Planting: Mid-August to mid-October is ideal for most native grasses. Planting in the fall allows roots to establish before winter sets in.
• Spring Planting: Early March through April is another option ^{[10] [11]}. However, spring plantings may face more weed competition and require extra watering during the summer.

Avoid planting after mid-October, as seeds may struggle to survive the winter and compete with winter weeds for nutrients ^[10]. Maryland’s first frost typically occurs between mid-October and mid-November, depending on your location.

Warm-season grasses like switchgrass grow best in summer (June–August) ^[1], but for strong root development, they should be planted in the fall or early spring.

If you’re not ready to plant immediately, sow a cover crop like cereal rye to improve soil structure and suppress weeds ^[12].

Planting and Establishing Native Grasses

When it comes to planting native grasses, the method you choose and the care you provide in the early months are crucial. These steps not only help the grasses take root but also ensure effective soil stabilization.

Seeding vs. Plug Planting

Both seeding and plug planting are effective ways to establish native grasses, each with its own advantages depending on your needs and budget.

Seeding is a budget-friendly option, especially for larger areas. It allows you to create custom seed mixes tailored to your site’s conditions, making it ideal for open spaces where erosion control is a priority. To seed properly, spread the seeds evenly over prepared soil at a depth of about 1/4 inch, lightly rake to cover them, and then firm the soil by rolling or packing the surface. This ensures good seed-to-soil contact, which is essential for germination and growth^[12].

Plug planting, on the other hand, is better suited for smaller areas or spots where erosion risk is higher and faster results are needed. Plugs, which typically cost about $1 each, come with established root systems, making them more resistant to surface runoff. Planting one plug per square foot helps achieve quick canopy closure. For best results, follow spacing recommendations and consider adding mulch between the plugs to protect the soil until the plants are fully established^[13].

Here’s a quick comparison:

For many projects, a combination of both methods works best – using plugs in high-risk areas and seeds for the rest. This approach balances cost and effectiveness^[14]. Once planted, proper watering and mulching are essential for success.

Watering and Mulching

Watering and mulching play a key role in helping native grasses establish strong roots.

Watering Tips: During the early stages, water seeds lightly and often to keep the topsoil moist. Once the grass reaches about 1 inch in height, shift to deeper, less frequent watering. This encourages the roots to grow deeper into the soil. Watering early in the morning is best – it minimizes runoff and reduces the risk of plant diseases^[15].

Mulching Guidelines: Organic mulches, like shredded bark, wood chips, pine needles, or straw, help retain soil moisture, regulate temperature, and add nutrients as they decompose. However, in dry or sunny areas, mulch can sometimes hold too much moisture, so it’s important to assess your site’s conditions before applying it^[9].

By focusing on these care practices, you’ll give your grasses the best chance to thrive.

Erosion Control During Establishment

The first few months after planting are critical for preventing soil erosion, as the grasses won’t yet have fully developed root systems.

Temporary Protection: To guard against erosion, consider using erosion control blankets or applying a light layer of straw mulch over seeded areas. These measures help reduce the impact of raindrops and slow down surface water movement.

Weed Management in the First Year: During the first year, monitor your planting closely and remove weeds promptly. Weeds compete with grasses for water and nutrients, so hand-pulling them early can make a big difference^[13].

With consistent care in the early stages, your native grasses will establish strong roots, creating a low-maintenance system that stabilizes soil, enhances your landscape, and supports local wildlife.

Maintaining Native Grasses for Long-Term Soil Stabilization

Once native grasses take root, they need consistent care to stay healthy and effective at preventing erosion. A little regular attention goes a long way in ensuring these plantings continue to stabilize your soil for years.

Managing Weeds and Unwanted Plants

Weeds can be a real nuisance, competing with native grasses for water, nutrients, and space. To keep them in check, monitor your landscape regularly, learn to identify common weed species, and act quickly when you spot new growth. Keeping the soil covered year-round is a smart way to block light, which reduces weed seed germination. For young weeds, manual removal works best – just be sure to get the roots out without disturbing the soil too much.

If you’re dealing with a particularly stubborn area, consider smothering seedlings with UV-stabilized plastic for two years. Once that’s done, plant a cover crop right away to prevent weeds from returning. Invasive plants are another challenge since they spread aggressively. Even after removing them, keep an eye out for regrowth and replace them with hardy native species that thrive in your local conditions.

Pruning and Seasonal Care

With weeds under control, shift your focus to pruning. Annual pruning, especially in early spring, helps keep native grasses in top shape. Trim back old growth and spent flowers to encourage fresh, vigorous growth. If clumps of grass start to look tired or overgrown, divide them to rejuvenate the stand.

In some cases, native prairie grasses respond well to periodic fires, which mimic natural processes. However, if you’re concerned about protecting insects that overwinter in your landscape, cutting back the grasses is a good alternative. Seasonal care like this not only supports plant health but also ensures long-term success.

Monitoring and Making Adjustments

Regular monitoring is key to keeping your native grasses thriving. Check for bare patches, weak growth, or invasive weeds, and address any issues as soon as they arise. During the early years, it’s especially important to manage competing vegetation through mowing, mechanical removal, or other targeted methods to give your grasses a solid foundation.

While native grasses require less maintenance than traditional lawns, occasional upkeep is still necessary. Periodic mowing, prescribed burns, or even controlled grazing can help maintain plant health and prevent invasive species from taking over. By staying attentive and making adjustments as needed, you can ensure your native grasses not only protect your soil but also support local wildlife and enhance the beauty of your Maryland landscape for years to come.

Adding Native Grasses to Your Landscape Design

Native grasses do more than just stabilize soil – they can elevate your landscape design with their natural beauty and practical benefits. When incorporated thoughtfully, these resilient plants create ecosystems that support local wildlife and require little upkeep, making them an excellent addition to any outdoor space.

Supporting Local Wildlife

Native grasses play a vital role in supporting wildlife by offering shelter, food, and nesting sites for pollinators, birds, and small mammals. Their unique structure, particularly that of warm-season grasses, creates habitats that cater to a variety of species. The bunching growth pattern of these grasses leaves open spaces at ground level, which are perfect for smaller creatures, while their vertical growth provides essential cover for birds and beneficial insects ^[1][2]. For a balanced habitat, aim for a mix of 50% native warm-season grasses and 50% forbs and shrubs ^[1].

Beyond shelter, native grasses also support pollinators in other ways. Butterflies use them as larval hosts, while native bees gather nesting materials from their stalks ^[20]. To maximize these benefits, avoid cutting back grasses like switchgrass until early spring, as their stalks provide crucial winter cover ^[3]. These ecological advantages make native grasses a seamless addition to landscapes, even when paired with hardscape features.

Combining with Hardscaping Features

Native grasses complement hardscape elements like patios, walls, and pergolas, creating a harmonious blend of natural and architectural design. While hardscaping provides structure and definition, grasses soften the edges and add privacy ^[18]. Plant beds with native grasses can frame patios and walkways, softening their rigid lines and enhancing the overall aesthetic ^[19].

When designing your outdoor space, consider dividing it into zones for activities like cooking, lounging, and dining, and use native grasses to create smooth transitions between these areas. For example, prairie dropseed, with its delicate seed heads, can add charm near seating areas, while the bold stature of big bluestem makes a striking backdrop for fire pits or outdoor kitchens. By varying heights and textures, you can create a dynamic and inviting landscape.
