Erosion Control Blankets and Turf Reinforcement Mats
1. Straw
Straw erosion control blankets are a budget-friendly and lightweight option for stabilizing soil in various projects [3]. Crafted from natural straw fibers, these blankets provide an affordable way for property owners to establish vegetation quickly while protecting against erosion.
Biodegradability
Straw blankets naturally break down over time, making them perfect for situations where fast vegetation growth is a priority [1][3]. As the fibers decompose, they enrich the soil with nutrients, improving its fertility [2][3]. This process not only offers short-term erosion control but also enhances the soil’s overall quality in the long run.
Lifespan
The lifespan of straw blankets depends on their composition and the surrounding environment. Typically, straw-based blankets decompose within 90 days to 1 year [1], making them suitable for short-term projects focused on rapid vegetation growth. For longer-term needs, straw/coconut blend blankets can last between 9 and 24 months [1]. Most straw blankets biodegrade within 6 months to 2 years [3], which is much faster compared to coir blankets that take 4 to 6 years to decompose [3]. This variability in lifespan allows for flexibility depending on the project’s requirements and environmental conditions.
Soil Stabilization Effectiveness
Straw blankets are most effective on gentle slopes, such as those with a 3:1 or 2:1 gradient, and in areas with minimal water flow [3]. While they may not be the best choice for steep slopes or regions with heavy water runoff, they do a great job of shielding soil from erosion caused by wind and light rain.
Vegetative Growth Support
A major benefit of straw blankets is their ability to promote healthy plant growth. They help retain soil moisture, which is critical for seed germination and early plant development [2]. As the blankets decompose, they further improve the soil by enhancing its structure and nutrient content [2][3]. This makes them an excellent choice for encouraging strong and healthy vegetation.
For Maryland property owners, straw blankets offer an eco-friendly and efficient solution for soil protection and quick vegetation establishment.
2. Coconut Coir
Coconut coir erosion control blankets are crafted from the natural fibers found between a coconut’s hard shell and its outer husk. Known for their strength and environmentally friendly qualities, these blankets are a practical choice for projects that need extended soil protection.
Biodegradability
One of the standout features of coconut coir blankets is their ability to break down naturally over time. As they decompose, they release organic matter into the soil, improving its structure and fertility. This natural process ensures that erosion protection continues as vegetation takes root and grows. The slower breakdown rate of coir blankets aligns with their durability, offering long-term support for soil stabilization.
Lifespan
Compared to straw alternatives, coir blankets last significantly longer, making them a great fit for projects that span multiple growing seasons. Their extended lifespan ensures that soil remains protected while vegetation establishes and matures.
Soil Stabilization Effectiveness
The tightly interwoven fibers of coir blankets provide excellent soil stabilization, especially on steep slopes. They effectively manage water flow, reducing soil displacement while maintaining moisture levels to prevent erosion.
Vegetative Growth Support
Coconut coir blankets create an ideal environment for seed germination and plant growth. They retain moisture, allow for proper air circulation, and filter sunlight, which helps protect seedlings from extreme temperatures. This combination promotes strong root development and healthy vegetation.
For Maryland property owners dealing with steep slopes or extended erosion concerns, coconut coir blankets offer a dependable and environmentally conscious solution. Pro Landscapes MD ensures expert installation for consistent and long-lasting results.
3. Wood Fiber (Excelsior)
Wood fiber erosion control blankets, commonly known as excelsior blankets, are crafted from curled wood fibers that naturally interlock to shield soil from erosion. The most effective versions use Great Lakes Aspen fibers, a renewable resource grown in the United States specifically for erosion control. This material stands out from alternatives like straw and coir, offering unique advantages for soil stabilization and vegetation support.
Biodegradability
Excelsior blankets break down gradually, ensuring soil protection during the critical establishment phase. As the material decomposes, it leaves no harmful residues, blending seamlessly into the soil. This gradual process allows vegetation to develop strong root systems, enhancing long-term stability.
Lifespan
The durability of excelsior blankets depends on their design. For instance, Curlex I is suited for moderate slopes, while Curlex II is engineered for more demanding terrains, offering extended durability. These blankets can perform effectively for several months to years, combining longevity with superior technical performance compared to more temporary materials.
Soil Stabilization Effectiveness
The fibers’ fine barbs and coils expand when exposed to moisture, improving their grip on the soil. Curlex I can stabilize slopes up to 2H:1V with a shear resistance of 84 Pa (1.75 lb/ft²). Meanwhile, Curlex II is designed for steeper slopes, handling up to 1.5H:1V with a shear resistance of 108 Pa (2.25 lb/ft²). It also contains approximately 50% more fibers (≈400 g/m² compared to 270 g/m²) [4], enhancing its stabilization capabilities.
Vegetative Growth Support
The interlocking fibers of excelsior blankets create a favorable environment for vegetation. They retain moisture, regulate temperatures, and protect seedlings, encouraging uniform growth. Even as the netting decomposes, the remaining fiber matrix continues to support root development, ensuring long-term erosion control.
For steep slopes and challenging sites in Maryland, excelsior blankets offer a reliable solution. With proper installation by Pro Landscapes MD, these high-performance materials deliver immediate soil protection and long-lasting support for vegetation establishment.

4. Jute Netting
Jute netting is an affordable and environmentally friendly choice for erosion control. Crafted from natural jute fibers woven into an open mesh, it provides temporary soil stabilization while vegetation establishes itself. The design allows for excellent seed-to-soil contact and water absorption, making it a practical foundation for erosion control efforts. Let’s take a closer look at its biodegradability, lifespan, soil stabilization capabilities, and support for vegetation.
Biodegradability
One of the standout features of jute netting is its ability to decompose naturally without leaving behind synthetic residues. Since it’s made entirely from biodegradable materials, it blends into the ecosystem as it breaks down, enriching the soil with organic matter. This eliminates the hassle of removal once vegetation has taken hold.
Lifespan
Jute netting typically lasts between 6 and 24 months, depending on environmental conditions. Under ideal circumstances – such as low-to-moderate slopes (up to 3:1) and water flows not exceeding 6 feet per second – it remains effective for about 6 to 9 months [5][6][7][8][9]. Factors like moisture levels, sunlight exposure, and proper installation play a significant role in determining its durability.
Soil Stabilization Effectiveness
This material works best on gentle to moderate slopes with manageable water flow. Its open mesh design protects the soil from raindrop impact and surface erosion, while still allowing plant roots to penetrate easily. However, on steeper slopes or areas with faster water flow, its lightweight nature may limit its effectiveness [8]. Proper installation, including overlapping rolls and ensuring tight contact with the soil, is critical for achieving the best results.
Vegetative Growth Support
Jute netting’s open weave design creates an ideal environment for seeds to germinate and plants to grow. The large openings allow sunlight and air to reach the soil, while also retaining enough moisture to promote even germination. As plants grow, their roots weave through the jute fibers, anchoring the soil and providing long-term erosion control as the material naturally decomposes.
For properties in Maryland dealing with moderate erosion issues, jute netting is an economical and sustainable solution that promotes healthy vegetation.
