Deschampsia cespitosa, commonly known as tufted hair grass, is a species of grass that is native to Europe, North Africa, and Western Asia. It is a perennial grass that is widely used for landscaping and lawn purposes due to its attractive foliage and ability to thrive in a variety of conditions. If you're looking to create a lush and vibrant lawn, here are 10 tips for growing Deschampsia cespitosa:
Understanding Deschampsia Cespitosa
Before we dive into the tips, it’s essential to understand the characteristics of Deschampsia cespitosa. This grass species is known for its dense, tufted growth habit and its ability to grow in a wide range of soils and climates. It is a cool-season grass, which means it thrives in temperatures between 40°F and 75°F (4°C and 24°C). Deschampsia cespitosa is also relatively low maintenance, requiring less watering and mowing than other grass species.
Tip 1: Choose the Right Soil
Deschampsia cespitosa can grow in a variety of soils, but it prefers well-draining soil with a pH between 6.0 and 7.0. If your soil is heavy clay or sandy, you may need to amend it with organic matter to improve its structure and drainage. A soil test can help you determine the pH and nutrient levels of your soil, allowing you to make informed decisions about fertilization and amendment.
Tip 2: Plant at the Right Time
The best time to plant Deschampsia cespitosa depends on your location and climate. In general, it’s best to plant in the fall or early spring, when the weather is cooler and there is ample moisture. Avoid planting in the heat of summer, as this can lead to stress and poor establishment.
Tip 3: Water Deeply but Infrequently
Deschampsia cespitosa prefers deep but infrequent watering. This encourages the grass to develop a deep root system, making it more drought-tolerant and resistant to disease. Aim to water your lawn about 1-2 inches per week, either from rainfall or irrigation.
Tip 4: Mow at the Right Height
The ideal mowing height for Deschampsia cespitosa is between 2-3 inches (5-7.5 cm). Mowing at this height helps to promote dense growth and prevent the grass from becoming leggy. It’s also essential to use a sharp mower blade to prevent tearing the grass and creating an entry point for diseases.
Tip 5: Fertilize Sparingly
Deschampsia cespitosa is a relatively low-fertilization grass species. Over-fertilization can lead to weak growth, disease, and environmental pollution. If you do need to fertilize, use a balanced fertilizer (e.g., 10-10-10 N-P-K) at a rate of about 1-2 pounds per 1,000 square feet.
Tip 6: Control Weeds
Weeds can compete with Deschampsia cespitosa for water, nutrients, and light. Use a pre-emergent herbicide in the spring to prevent crabgrass and other annual weeds from germinating. For perennial weeds, use a post-emergent herbicide or manually remove them by digging or pulling.
Tip 7: Monitor for Pests and Diseases
Deschampsia cespitosa is generally resistant to pests and diseases, but it’s still essential to monitor your lawn regularly. Look for signs of powdery mildew, rust, or leaf spot, and treat promptly if necessary. Common pests include white grubs and billbugs, which can be controlled with insecticides or biological agents.
Tip 8: Overseed as Needed
Overseeding can help to fill in bare spots and improve the overall density of your Deschampsia cespitosa lawn. Use a high-quality seed mix that is specifically formulated for your climate and soil type. Apply the seed at a rate of about 1-2 pounds per 1,000 square feet, and rake it in gently to ensure good contact with the soil.
Tip 9: Aerate and Dethatch
Aerating and dethatching can help to improve the overall health and appearance of your Deschampsia cespitosa lawn. Aerating involves removing small plugs of soil to improve drainage and reduce soil compaction. Dethatching involves removing dead grass and debris to promote new growth and prevent thatch buildup.
Tip 10: Be Patient
Deschampsia cespitosa is a slow-growing grass species that can take time to establish. Be patient and give your lawn the time it needs to develop a strong root system and dense growth habit. With proper care and maintenance, your Deschampsia cespitosa lawn can become a lush and vibrant oasis that requires minimal upkeep.

What is the ideal temperature for growing Deschampsia cespitosa?
+
Deschampsia cespitosa thrives in temperatures between 40°F and 75°F (4°C and 24°C), making it an ideal cool-season grass for temperate climates.
How often should I water my Deschampsia cespitosa lawn?
+
Water your Deschampsia cespitosa lawn deeply but infrequently, aiming for about 1-2 inches of water per week. This encourages deep root growth and makes the grass more drought-tolerant.
Can I grow Deschampsia cespitosa in shady areas?
+
While Deschampsia cespitosa prefers full sun to partial shade, it can tolerate shady areas with dappled sunlight. However, it may require more frequent watering and fertilization to thrive in shadier conditions.
