A strong ground cover for grass seed protects seed from washout and wind while helping the soil stay moist; the best format depends on whether you need a small patch repaired or a larger, sloped area stabilized. This roundup compares six options: a biodegradable mat that already contains grass seed, loose straw with tackifier, straw and erosion-control blankets, and a paper mulch with starter fertilizer. Coverage, included installation supplies, and materials vary, so match the product to your seeding area and conditions rather than assuming every cover works the same way.
For quick patch repairs, a seeded roll can simplify the process. For hills or places exposed to runoff, a blanket designed to stay in place may be a better fit.
Check each product’s specific coverage and installation needs before buying.
Growtrax Grass Seed Mat leads because it combines grass seed, natural mulch, and biodegradable fabric in a roll designed for lawns, dog patches, and shade. Its 50-square-foot coverage makes it a focused option for smaller repairs, and the listed directions are simple: roll, water, and grow. For larger seeded areas or slopes, compare it with the 200-square-foot EZ Straw Erosion Blanket, which includes 15 biodegradable stakes, or the erosion-focused QuickGrass Pro Blanket.

Detailed Reviews: Best Ground Cover For Grass Seed
#1 · Best Overall
1. Growtrax Grass Seed Mat
- Material Feature: Biodegradable fabric, premium grass seed…
- Material Features: Biodegradable fabric, premium grass seed…
Best for: Quick patch coverage.
Why it ranks #1: Combines premium grass seed, natural mulch, and biodegradable fabric in a 50-square-foot roll for patches, lawns, and shade; roll and water to use.
A 50-square-foot biodegradable mat combines grass seed with natural mulch, letting you roll a prepared covering directly over lawn patches instead of spreading seed and mulch separately. GROWTRAX positions this Year Round Green roll for lawns, dog patches, and shade, with a simple roll-and-water approach for starting a repair.
The integrated seed, mulch, and biodegradable fabric keep the main components together in one roll, simplifying placement over bare spots. Its 50-square-foot coverage gives you a defined area to plan around, while the roll-and-water directions make application straightforward: unroll it where you want grass and water. The product is specifically presented for lawns, dog patches, and shade, so it suits targeted repair areas; it is a seed mat, not artificial grass.
- Combines grass seed, natural mulch, and biodegradable fabric
- Covers 50 square feet per roll
- Roll-and-water application
- Listed for lawns, dog patches, and shade
- One roll covers only 50 square feet, limiting how much area it can treat.
Skip it if you need to cover a broad area with loose straw rather than place a seed-containing mat; EZ Straw Seeding Mulch covers up to 500 square feet.
Choose this roll for a defined lawn repair, dog patch, or shaded spot where an integrated seed-and-mulch mat simplifies placement. Its 50-square-foot coverage is the key boundary when planning larger seeding areas.

2. EZ Straw Erosion Blanket
- Material Feature: Biodegradable
- Material Features: Biodegradable
Best for: Slopes with included stakes.
Why it ranks #2: Covers 200 square feet, is biodegradable, and includes 15 wood stakes and an installation guide; its straw blanket suits slopes and embankments.
Fifteen biodegradable wood stakes come with this 4-by-50-foot straw blanket, helping secure seed cover on slopes, hills, embankments, ditch bottoms, and stream banks. Its processed straw fibers form a blanket that is intended to support faster germination while limiting erosion and seed drift.
The included stakes and installation guide make it easier to secure the blanket to the ground, while its cuttable format helps adapt the cover to the area. Clean processed straw is described as non-toxic and biodegradable, and the blanket helps keep seed from washing or blowing away. At 200 square feet, it offers a defined coverage area for banks and slopes; it requires grass seed and water as part of the seeding workflow.
- Includes 15 biodegradable wood stakes
- Covers 200 square feet
- Can be cut to fit an area
- Intended for slopes, hills, embankments, ditch bottoms, and stream banks
- The 200-square-foot blanket may require additional coverage for larger projects.
Skip it if you need a moisture-retaining cover that also contains starter fertilizer; GreenView Grass Seed Starting Mulch combines mulch and fertilizer.
Pick this blanket for seeded slopes or banks where included stakes simplify securing a straw cover. Its 200-square-foot coverage sets the planning limit, and it is a protective blanket rather than a product containing grass seed.

3. QuickGrass Pro Blanket
- Weight: 16 lb
- Material Feature: Organic
- Material Features: Organic
Best for: Slopes needing erosion control.
Why it ranks #3: The 4-by-50-foot blanket is designed to stop erosion on hills and slopes, retain water, protect seed, and comply with most stormwater regulations.
A 4-by-50-foot degradable blanket helps protect seed from birds and sun heat while supporting water retention, giving slopes and concentrated-flow areas a protective cover. American Excelsior says QuickGrass Pro is weed-seed-free and intended to enhance germination and vegetation establishment, without supplying grass seed itself.
The blanket’s water-retention benefit supports germination, while its fibers cling to one another to help maintain the covering. It is identified for hills, slopes, and concentrated flow, and the product states that it complies with most stormwater management regulations. Installation calls for preparing topsoil, spreading or raking in seed, then unrolling the blanket with netting up and securing it with landscaping stakes. Those stakes are not included, so plan for them separately.
- 4-by-50-foot blanket format
- Helps retain water and protect seed from birds and sun heat
- Listed for hills, slopes, and concentrated flow
- Degradable and weed-seed-free
- Landscaping stakes needed for installation are not included.
Skip it if you want a slope blanket with stakes included; EZ Straw Grass Seed Germination and Erosion Control Blanket comes with 15 biodegradable stakes.
This is a fit for slope or concentrated-flow projects needing a degradable seed cover and a 4-by-50-foot roll. Bring landscaping stakes, and supply grass seed separately because the blanket contains no grass or weed seed.

4. GreenView Starting Mulch
- Weight: 18 lb
Best for: Moisture-retaining seed starter.
Why it ranks #4: This 18-pound pellet mulch includes starter fertilizer and holds three times its weight in water, helping keep seed moist as it germinates.
Pellets that hold three times their weight in water give this grass-seed mulch a moisture-retaining role, while included starter fertilizer supports new root development. GreenView combines paper mulch and fertilizer for newly seeded lawns and bare spots, so one applied cover addresses moisture and feeding in the same step.
Apply grass seed first, then the pellet-form mulch and water; the product expands when watered to help maintain moisture over the seeded area. Its fertilizer contains nitrogen, phosphorus, and potassium, with the stated purpose of encouraging strong new roots. That combination suits lawn renovation or fall overseeding workflows where seed has already been spread. The 18-pound bag includes fertilizer, but the supplied directions call for grass seed of your choice, not seed included in the product.
- Pellets hold three times their weight in water
- Includes starter fertilizer for root development
- Paper mulch expands when watered
- For newly seeded lawns and bare spots
- Grass seed is not included; the directions call for applying seed separately.
Skip it if you want grass seed already combined with the cover; GROWTRAX Year Round Green is a seed-containing biodegradable mat.
This fits homeowners overseeding or repairing bare spots who want moisture-retaining mulch and starter fertilizer in one application. Have grass seed ready first; the 18-pound bag is a cover and fertilizer, not a seed mixture.

5. Farm Plastic Straw Blanket
- Weight: 39 lb
Best for: Narrow slope stabilization.
Why it ranks #5: Its 2-by-112.5-foot straw blanket is designed to retain soil moisture and reduce erosion from rainfall and stormwater sheet flow.
Its 2-foot-wide, 112.5-foot-long straw blanket gives you a long, narrow strip for erosion-prone ground, while retaining soil moisture to support seed germination. Farm Plastic Supply identifies rainfall impact and stormwater sheet flow as erosion concerns this blanket addresses, making it relevant to slope and landscape cover work.
The blanket is described as a strong mat that helps prevent soil erosion from rainfall impact and stormwater sheet flow. Its moisture-retaining function supports seed germination and vegetation growth by keeping soil moist beneath the cover. At 2 feet wide and 112.5 feet long, the roll offers a narrow format that can be laid along an area; the listed dimensions are useful when planning coverage, though installation instructions and fastening details are not provided in the supplied facts.
- Helps prevent erosion from rainfall impact and sheet flow
- Retains soil moisture to support germination
- Strong mat construction
- Measures 2 feet by 112.5 feet
- The 2-foot width means it takes multiple adjacent strips to cover wider ground.
Skip it if you need a 4-foot-wide blanket to cover a broader strip; American Excelsior QuickGrass Pro measures 4 by 50 feet.
Consider this long, narrow blanket for erosion-prone landscape areas where moisture retention and seed protection matter. Its 2-foot width is the main fit consideration for wider slopes or ground that needs multiple adjacent strips.

6. EZ-Straw Seeding Mulch
- Weight: 21 lb
- Material Feature: Natural
- Material Features: Natural
Best for: Windy or washout-prone lawns.
Why it ranks #6: Natural processed straw with biodegradable tackifier helps guard seed against wind and washout; water activates the bonding agent.
A biodegradable tackifier helps this processed straw hold together in wind and washout, giving newly sown grass seed a protective cover where loose mulch may shift. EZ-Straw also says the straw protects seed from birds and other animals, making this bale a practical option for exposed seeding areas.
The natural bonding agent activates with water, helping bind the straw after it is laid over seeded ground. That cohesion is intended to reduce movement in windy conditions and during washout, while the straw helps keep soil moist and can reduce watering. The 2.5-cubic-foot bale covers up to 500 square feet, and its handled, bagged format is described as convenient; it is a mulch cover, not a pre-seeded mat.
- Tackifier helps straw stay together in wind and washout
- Protects seed from birds and other animals
- Straw helps retain soil moisture and reduce watering
- Covers up to 500 square feet
- Water is required to activate the tackifier bonding agent.
Skip it if you want a secured blanket with installation stakes included; EZ Straw Grass Seed Germination and Erosion Control Blanket includes 15 biodegradable stakes.
This suits gardeners covering seeded ground exposed to wind or washout who want straw that binds after watering. Choose it for broad mulch coverage, but account for the water needed to activate the tackifier.

Listed on Amazon as: EZ-Straw Seeding Mulch with Tackifier – Biodegradable Organic Processed Straw a 2.5 CU FT Bale (Covers up to 500 sq. ft.)
View on AmazonAvoiding washout and cover movement
On exposed ground, the main failure to avoid is cover shifting or seed washing away before it establishes. The loose EZ-Straw Seeding Mulch uses a tackifier that activates with water and helps bind straw in windy or washout conditions. For a more structured cover, the EZ Straw Erosion Blanket includes 15 wood stakes, while the QuickGrass Pro Blanket must be secured with landscaping stakes that are not included.
Those are different setup expectations: check what fastening supplies come with the product before starting. Blanket coverage does not remove the need to prepare the seedbed; QuickGrass instructions say to spread or rake seed into prepared topsoil before unrolling the blanket.
On sloped sites, match the fastening approach to the area and follow the product’s installation directions. A cover that is not secured as intended can fail to protect seed, even if its material is suitable.
Check the coverage shape before ordering
Coverage area alone can hide a fit problem: a narrow roll may not suit a broad patch without extra cutting or seams. The Growtrax Grass Seed Mat covers 50 square feet, while the EZ Straw Erosion Blanket and QuickGrass Pro Blanket each cover 200 square feet; the Farm Plastic Straw Blanket measures 2 by 112.5 feet, or 225 square feet. The 2-foot width of the Farm Plastic roll may be useful for long, narrow runs, but can mean more side-by-side placement across a wide lawn.
The 4-foot-wide blankets cover broader strips per pass. Loose mulch and pellets do not provide a listed roll dimension, so estimate the area and confirm the package’s coverage directions before relying on them.
Measure the bare or seeded area and allow for the actual shape of the site, not just its total square footage.
How to Choose Grass Seed Ground Cover
Cover format and seed inclusion
Choose a format based on whether you want the seed included or already have seed to protect. Growtrax Grass Seed Mat combines seed, natural mulch, and biodegradable fabric in one 50-square-foot roll. The other listed products are covers or mulches for seed you apply separately: the EZ Straw and Farm Plastic products are straw-based blankets, while GreenView Starting Mulch is a paper mulch and fertilizer product.
Buyers repairing a small patch who want seed in the cover may prefer Growtrax; those overseeding with their own seed can choose among blankets and mulches. Confirm the seed type is appropriate for your lawn, since the supplied data does not identify the varieties in the Growtrax mat.
Area, dimensions, and layout
Look for a listed area or roll dimension that suits the shape of your seeding site. Growtrax Grass Seed Mat covers 50 square feet; the EZ Straw Erosion Blanket and QuickGrass Pro Blanket each cover 200 square feet; and the Farm Plastic Straw Blanket measures 2 by 112.5 feet, totaling 225 square feet. A 4-foot-wide blanket can cover a wider strip in each pass, while the 2-foot-wide Farm Plastic roll may better fit narrow runs.
For small repairs, the 50-square-foot mat is more targeted. For a larger site, compare the blanket coverage and width with your measured area.
The loose straw and pellet mulch listings do not state coverage area, so check package directions for your required quantity.
Moisture and installation needs
Consider how the cover retains moisture and what you need to secure or apply it. QuickGrass Pro Blanket is described as providing water retention and needs landscaping stakes, which are not included. EZ Straw Erosion Blanket includes 15 wood stakes, while EZ-Straw Seeding Mulch uses water to activate its tackifier.
GreenView Starting Mulch pellets hold three times their weight in water and include starter fertilizer; the directions say to apply seed, spread the product, and water. Buyers prioritizing included fastening supplies can favor EZ Straw Erosion Blanket.
Those seeking a moisture-retaining mulch with fertilizer can consider GreenView, while a site exposed to wind may suit tackified straw. Follow each product’s stated preparation and application instructions.
Which Grass Seed Cover Should You Choose?
For a small lawn repair where you want seed and cover together, choose Growtrax Grass Seed Mat: its 50-square-foot biodegradable roll includes seed and natural mulch. For a slope or embankment needing a secured blanket, EZ Straw Erosion Blanket covers 200 square feet and includes 15 stakes. Choose QuickGrass Pro Blanket for erosion control on hills and slopes, especially if its 4-by-50-foot dimensions suit your layout and you can supply stakes.
For newly seeded areas where moisture retention and starter fertilizer matter, GreenView Starting Mulch offers pellets that hold three times their weight in water. Farm Plastic Straw Blanket is a 225-square-foot option in a narrow 2-foot width.
For loose straw with a bonding agent, EZ-Straw Seeding Mulch is the simpler cover format.

Frequently Asked Questions
How do I keep grass seed cover from washing away on a slope?
Choose a blanket designed for erosion control and secure it as directed so it stays in place on the slope. The EZ Straw blanket covers 200 square feet and includes 15 biodegradable stakes; QuickGrass Pro is another erosion-focused option, but you’ll need to supply stakes. Match the blanket dimensions to your layout.
Should I use a blanket or loose mulch over newly seeded grass?
Use a blanket when erosion control on a hill or slope is a priority; loose mulch is a simpler cover for seeded areas. The listed blanket options include erosion-control formats, while EZ-Straw Seeding Mulch is processed straw with a bonding agent. GreenView Starting Mulch is a pellet option for moisture retention.
How much grass seed cover should I buy for my lawn area?
Measure the area you plan to cover, then compare it with each product’s stated coverage and dimensions. Growtrax covers 50 square feet, EZ Straw’s blanket covers 200, and Farm Plastic Straw Blanket covers EZ-Straw Seeding Mulch states coverage up to 500 square feet; check the product directions for your application.
Which cover is suited to a small lawn repair?
For a small repair where you want seed and cover together, Growtrax is the focused choice. Its 50-square-foot biodegradable roll combines grass seed, natural mulch, and fabric, and the listed directions are to roll, water, and grow. Check that its coverage matches the patch before choosing it.
When should I choose starting mulch over a straw blanket?
Choose GreenView Starting Mulch when moisture retention and starter fertilizer matter for a newly seeded area; its pellets hold three times their weight in water. Choose a straw blanket when erosion control is the priority, particularly on a slope. The formats address different needs, so base the choice on the site.
Final Words
For a small repair where you want seed and cover together, Growtrax is the practical first choice: its biodegradable roll includes seed and natural mulch. For a slope or larger area, compare the 200-square-foot EZ Straw blanket with QuickGrass Pro, accounting for whether you need to supply stakes. Choose loose EZ-Straw Seeding Mulch for a simpler straw cover, or GreenView when moisture retention and starter fertilizer are priorities.
Match coverage and format to your site.
