Native grasses offer a beautiful and sustainable alternative to traditional lawns. They are adapted to the local climate, require less water and fertilizer, and provide valuable habitat for wildlife. Successfully planting native grass, however, requires understanding the specific needs of your chosen species and meticulous preparation. This guide will walk you through every step, from selecting the right grass to establishing a healthy, thriving native lawn.
Choosing the Right Native Grass Species
The success of your native grass planting hinges on selecting species that are well-suited to your specific environment. Consider factors such as your region’s climate, soil type, and the amount of sunlight your planting area receives.
Understanding Your Region’s Climate
Native grasses are inherently adapted to the climate in which they evolved. Planting a species outside of its natural range often leads to poor growth, increased susceptibility to disease, and a greater need for supplemental watering and fertilization.
Research the native grasses that thrive in your specific USDA plant hardiness zone. Local nurseries, agricultural extension offices, and native plant societies are excellent resources for identifying appropriate species.
Consider the average rainfall, temperature extremes, and growing season length in your area. Some native grasses prefer drier conditions, while others tolerate wetter soils. Similarly, some species are more cold-hardy than others.
Analyzing Your Soil Type
Soil type significantly impacts the growth and health of native grasses. Different species have varying preferences for soil texture, drainage, and nutrient levels.
Conduct a soil test to determine the pH, nutrient content, and texture of your soil. You can purchase soil testing kits online or from garden centers, or send a sample to a professional soil testing laboratory.
Native grasses generally prefer well-drained soils. If your soil is heavy clay, amend it with compost, sand, or other organic matter to improve drainage. If your soil is sandy, add organic matter to increase its water-holding capacity.
Consider the nutrient levels in your soil. Native grasses often thrive in soils that are relatively low in nutrients. Avoid over-fertilizing, as this can favor the growth of weeds and reduce the competitiveness of your native grasses.
Assessing Sunlight Exposure
The amount of sunlight your planting area receives is another crucial factor to consider when selecting native grass species. Some species require full sun (at least six hours of direct sunlight per day), while others tolerate partial shade.
Observe your planting area throughout the day to determine the amount of sunlight it receives. Note any areas that are shaded by trees, buildings, or other structures.
Choose native grass species that are appropriate for the amount of sunlight your planting area receives. Planting a shade-tolerant species in full sun can scorch the leaves, while planting a sun-loving species in shade can result in weak, spindly growth.
Preparing the Planting Site
Proper site preparation is essential for establishing a healthy native grass lawn. This involves removing existing vegetation, amending the soil, and ensuring adequate drainage.
Removing Existing Vegetation
Before planting native grass, it is crucial to remove all existing vegetation, including weeds, grasses, and other plants. This will reduce competition for resources and give your native grass seedlings a better chance of survival.
Several methods can be used to remove existing vegetation, including:
- Herbicide application: A non-selective herbicide, such as glyphosate, can be used to kill all vegetation in the planting area. Follow the manufacturer’s instructions carefully and apply the herbicide when the vegetation is actively growing. Note this method can negatively impact the soil.
- Solarization: Cover the planting area with clear plastic for several weeks during the hottest part of the year. The trapped heat will kill the vegetation and weed seeds in the soil.
- Tilling: Tilling can be used to break up the soil and bury existing vegetation. However, tilling can also bring weed seeds to the surface, so it is important to monitor the area closely for weeds after tilling.
- Smothering: Covering the area with cardboard or thick layers of mulch for an extended period can smother existing vegetation.
Amending the Soil
As mentioned earlier, soil testing is crucial to determine if soil amendments are necessary. Most native grasses prefer slightly acidic to neutral soil, but it’s always best to confirm with a soil test.
Amend the soil with compost or other organic matter to improve drainage, aeration, and nutrient retention. Incorporate the amendments into the top 6-8 inches of soil.
Avoid adding excessive amounts of fertilizer, as this can favor the growth of weeds and reduce the competitiveness of your native grasses. If your soil is deficient in certain nutrients, add only the amount recommended by your soil test results.
Ensuring Adequate Drainage
Native grasses generally prefer well-drained soils. If your soil is poorly drained, consider installing drainage tiles or creating raised beds to improve drainage.
Avoid planting native grasses in areas where water tends to pool or stand for extended periods. This can lead to root rot and other problems.
Planting Native Grass Seeds or Plugs
Native grasses can be planted from seed or plugs (small, established plants). Each method has its own advantages and disadvantages.
Planting Native Grass Seeds
Planting native grass from seed is a more economical option than planting plugs, but it also requires more patience and effort.
The best time to plant native grass seeds is typically in the late fall or early spring. This allows the seeds to germinate and establish themselves before the hot, dry summer months.
Prepare a smooth, firm seedbed by raking the soil and removing any rocks or debris. Broadcast the seeds evenly over the planting area, using a seed spreader or by hand.
Lightly rake the seeds into the soil to ensure good seed-to-soil contact. Avoid burying the seeds too deeply, as this can prevent germination.
Water the planting area gently and frequently to keep the soil moist until the seeds germinate. Avoid overwatering, as this can wash away the seeds or promote the growth of weeds.
Consider using a seed drill for larger areas to ensure uniform planting depth and spacing.
Planting Native Grass Plugs
Planting native grass plugs is a more expensive option than planting seeds, but it also offers a higher success rate and faster establishment.
The best time to plant native grass plugs is typically in the spring or fall. Choose healthy, vigorous plugs from a reputable nursery.
Dig holes that are slightly larger than the root balls of the plugs. Space the plugs according to the recommendations of the nursery or seed supplier.
Gently remove the plugs from their containers and place them in the holes. Backfill the holes with soil and gently firm the soil around the plugs.
Water the plugs thoroughly after planting and continue to water them regularly until they are established.
Consider using a fertilizer specifically formulated for native plants to encourage root growth.
Caring for Your Native Grass Lawn
Once your native grass is established, it requires relatively little maintenance. However, some basic care is necessary to keep it healthy and thriving.
Watering
Native grasses are generally drought-tolerant, but they may need supplemental watering during prolonged periods of drought.
Water deeply and infrequently, rather than shallowly and frequently. This encourages deep root growth and makes the grass more resistant to drought.
Avoid overwatering, as this can lead to root rot and other problems. Allow the soil to dry out slightly between waterings.
Mowing
The mowing height for native grasses varies depending on the species. Some species can be mowed relatively short, while others should be left taller.
Mow your native grass lawn only when necessary. Frequent mowing can stress the grass and reduce its ability to compete with weeds.
Leave the grass clippings on the lawn after mowing. This provides valuable nutrients to the soil.
Consider using a mulching mower to finely chop the grass clippings and return them to the soil.
Weeding
Weeds can be a problem in native grass lawns, especially during the establishment phase.
Hand-pull weeds regularly, especially during the first year after planting.
Consider using a selective herbicide to control broadleaf weeds. Follow the manufacturer’s instructions carefully and avoid spraying the herbicide on desirable grasses.
Promote the growth of your native grasses by providing adequate sunlight, water, and nutrients. A healthy, vigorous native grass lawn will be better able to compete with weeds.
Fertilizing
Native grasses generally do not require frequent fertilization. In fact, over-fertilizing can actually harm them.
If your soil is deficient in certain nutrients, apply a fertilizer specifically formulated for native plants. Follow the recommendations of your soil test results.
Avoid using fertilizers that are high in nitrogen. Nitrogen promotes rapid growth, which can make the grass more susceptible to disease and pests.
Consider using a slow-release fertilizer to provide a steady supply of nutrients over a longer period of time.
Controlling Pests and Diseases
Native grasses are generally resistant to pests and diseases. However, they can occasionally be affected by certain problems.
Monitor your native grass lawn regularly for signs of pests or diseases. If you notice any problems, take action promptly to control them.
Use integrated pest management (IPM) techniques to control pests and diseases. IPM involves using a variety of methods to minimize the use of pesticides and other chemicals.
Consult with a local extension agent or plant pathologist for help identifying and controlling pests and diseases.

What are the benefits of planting native grasses instead of traditional turfgrass?
Native grasses offer a multitude of ecological and practical advantages over traditional turfgrass lawns. They are adapted to the local climate and soil conditions, requiring less watering, fertilization, and mowing. This translates to lower maintenance costs, reduced water consumption, and decreased reliance on chemical inputs, contributing to a more sustainable lifestyle and environment.
Furthermore, native grasses provide vital habitat and food sources for local wildlife, including pollinators like bees and butterflies, as well as birds and beneficial insects. They contribute to increased biodiversity, create a more natural landscape aesthetic, and enhance the overall health and resilience of the surrounding ecosystem. By choosing native grasses, you’re supporting a healthier planet.
How do I determine which native grasses are best suited for my region and soil type?
Identifying the right native grasses for your specific location is crucial for successful establishment and long-term growth. Consult with your local extension office, native plant society, or a reputable native plant nursery. These resources can provide valuable information about native grass species that thrive in your climate zone, soil type, and average rainfall.
Pay attention to factors such as sunlight exposure (full sun, partial shade, or full shade), soil drainage (well-drained, moderately drained, or poorly drained), and soil pH (acidic, neutral, or alkaline). Choose grasses that are specifically recommended for your area and that match your site conditions to ensure optimal performance and minimize maintenance needs.
What is the best time of year to plant native grasses?
The optimal planting time for native grasses depends on your region’s climate. In general, the best times are early spring or late fall. Spring planting allows the grasses to establish roots before the heat of summer, while fall planting gives them a head start before the winter dormancy period.
Consider planting in late spring if you live in an area with cold winters to avoid frost damage to young seedlings. In warmer climates, fall planting can be ideal, allowing the grasses to take root during the cooler, wetter months. Always check with local resources or a native plant expert for specific recommendations tailored to your area’s weather patterns.
How should I prepare the soil before planting native grass?
Proper soil preparation is essential for successful native grass establishment. Start by removing existing turfgrass, weeds, and debris from the planting area. This can be done manually, with herbicides, or through solarization. Next, conduct a soil test to determine its pH and nutrient levels.
Amend the soil based on the soil test results, adding compost or other organic matter to improve drainage, aeration, and fertility. If the soil is compacted, till it to a depth of 6-8 inches to loosen it. Rake the soil smooth and level before planting, creating a firm seedbed.
What are the different methods of planting native grass?
Native grass can be planted using various methods, including seeding, plugs, and sod. Seeding is the most common and cost-effective method, especially for large areas. However, it requires more patience and careful attention to watering and weed control during the initial establishment phase.
Plugs are small, pre-grown plants that are transplanted into the ground. This method provides faster establishment and better weed competition, but it is more expensive than seeding. Sod is a less common method for native grasses, but it can be used for small areas requiring immediate ground cover. Choose the method that best suits your budget, time commitment, and desired outcome.
How often should I water native grass after planting?
Watering frequency after planting native grass is crucial for successful establishment. During the first few weeks, water daily or every other day to keep the soil consistently moist but not waterlogged. This helps the seeds germinate and the young plants develop strong roots.
Once the grasses are established (usually after a few months), gradually reduce watering frequency. Native grasses are drought-tolerant and require minimal supplemental irrigation once they are mature. Overwatering can lead to fungal diseases and weed problems, so it’s important to allow the soil to dry out slightly between waterings.
How can I control weeds in a native grass lawn?
Weed control is an important aspect of maintaining a healthy native grass lawn, especially during the establishment phase. Manual weeding is effective for small areas and allows you to target specific weeds without harming the native grasses. Mulching with organic materials like straw or wood chips can also suppress weed growth.
For larger areas, consider using pre-emergent herbicides before planting to prevent weed seeds from germinating. Post-emergent herbicides can be used to control existing weeds, but be sure to choose products that are safe for native grasses. Regular mowing can also help to prevent weeds from going to seed, maintaining the health and beauty of your native lawn.
