If you have a sloped yard, a freshly graded patch, or a ditch that washes out every time it rains, loose straw just blows away. What you need instead is a blanket — a mat of natural fibers that stays put, holds the soil, and lets grass or plants grow right through it. The challenge is picking the right material and weight so it does the job without falling apart too fast or costing a fortune.
I’m Rikta — the founder and writer behind Lawn Gear Lab. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you are covering a hillside for a new lawn, protecting a drainage ditch, or establishing ground cover on a difficult slope, the right biodegradable erosion control blanket acts like a temporary shield that disappears naturally once your plants take over.
Our Picks at a Glance
How To Choose The Best Biodegradable Erosion Control Blanket
A biodegradable erosion control blanket is basically a fabric mat made from natural fibers like jute, straw, or coir. You roll it out over bare soil, pin it down, and it protects the ground from rain and wind while grass or other plants sprout. The blanket keeps the seed and topsoil in place, then breaks down naturally over a season or two. The key decisions come down to material, weight, and coverage.
Material: Jute vs Straw
Jute is a natural plant fiber that makes a dense, burlap-like fabric. It is heavier and lasts longer — typically a year or more — so you use it on steeper slopes or areas that take longer to vegetate. Straw blankets are lighter and decompose faster, which works well on gentle grades where you expect quick grass growth. The trade-off is density: a straw blanket is bulkier and can shed fill material if cut into small pieces.
Weight and Density
A blanket’s weight per square yard often tells you how tough it is. A lightweight straw blanket might weigh around half a pound per square yard, while heavy jute nets can exceed 13 ounces per square foot (roughly 400 GSM, a unit that stands for grams per square meter — think of it as how tightly packed the fibers are). Heavier blankets stand up to harder rain and hold soil longer, but they cost more per roll and are heavier to carry.
Installation and Area
Check the length and width of the roll so you know how many you need. The dimensions also affect handling — a 4-foot wide by 50-foot roll covers 200 square feet and is manageable for one person, while a 112.5-foot roll at 2 feet wide covers 225 square feet but requires a second person to unroll neatly. You anchor the blanket with U-shaped landscape staples — typically 6-inch pins every 12 to 18 inches along seams and in the center.

In‑Depth Reviews
1. AK TRADING CO. Jute Erosion Control Blanket
Our pick — 4.5★ from 200+ verified ratings; the strongest balance of quality and price.
The heavy jute blanket that weathered a storm and kept bare soil in place.
This blanket gives you the widest coverage in the jute category — 48 inches wide by 20 yards long covers 240 square feet, meaning fewer rolls to buy and less overlapping on a big slope. It is built from premium jute fibers loosely woven with roughly 2-inch holes, so grass shoots push right through while the mat holds the dirt underneath. Buyers report that after heavy rain the blanket stayed in place and held bare soil, even on a repaired culvert.
At 12.63 kilograms (about 28 pounds) it is not the lightest roll, but that weight comes from dense jute that resists UV rays and weather breakdown longer than a straw blanket. One reviewer noted it survived chicken scratching for a full year before starting to break down naturally — right on schedule for establishment of deep-rooted ground cover. The ease of cutting and shaping it around obstacles makes it practical for irregular terrain.
Unlike the straw options below that can feel thin or shed fill, this jute blanket delivers consistent density across the whole roll. The catch is the price per roll sits at a premium tier, so for a large property the upfront cost adds up. For challenging slopes where a lightweight blanket would tear or slide, this investment pays off.
Why it stands out
- Covers 240 square feet per roll — cuts down on trips to the store
- Loosely woven (2-inch gaps) lets grass and plants grow through easily
- Buyers confirm it survived heavy rain and stayed in place on bare soil
The honest limit
- Premium price per roll — sticker shock if you need several for a large area
- Not the heaviest-duty jute available; lasts 2-3 seasons before eroding
Take it home if: you are dealing with a steep, eroding slope or a drainage area that needs a durable jute blanket that outlasts a straw mat and holds through heavy rain.
Think twice if: your budget is very tight and you need to cover a flat, small patch — a lighter blanket might do the job for less.
2. Sandbaggy Jute Netting Roll
Contractor-approved jute rated to last 6-24 months while grass roots dig in.
Sandbaggy markets this directly to construction sites and road projects, meaning it meets federal and state erosion control standards that some consumer-oriented blankets skip. It is made from 100% natural jute fiber with a density that withstands heavy rains and water runoff until plants establish deep roots — the manufacturer says it typically lasts 6 to 24 months before fully decomposing. The 48-inch by 30-foot roll covers 120 square feet, so you cover half the area of the AK TRADING Co. roll at a comparable price point.
A retired erosion control professional who bought this for his own lawn confirmed it held soil through storms and let grass germinate after two weeks. He pointed out the jute’s distinctive smell, which fades once the blanket is installed and aired out. The 1-inch gaps between the woven fibers are tight enough to stabilize soil but open enough for ryegrass and bermudagrass to push through. One review mentioned that armadillos tore through the netting after three months — a real consideration if you have digging wildlife.
Compared to the AK TRADING Co. blanket, this Sandbaggy roll is denser and has a more formal contractor pedigree, but it covers only half the area. If you are managing a large slope, you will need more rolls, and each one is pricey — one buyer mentioned they would use 6 to 8 more rolls if the price came down. It is best for a smaller critical area where you want a blanket that meets regulatory specs.
Built for the pros: Engineered to DOT standards, so it carries more documentation and testing for demanding sites. The 6-24 month lifespan gives it a longer window for slow-growing native plants.
Reach for this if: you need a blanket for a drainage ditch, roadside bank, or any area that requires a certified erosion control product that meets state specs.
Look elsewhere if: you are covering a large residential yard — the smaller roll size and high cost per square foot make it a poor value for big areas.
3. Agfabric 4x112ft Natural Jute Erosion Control
The longest jute roll at 112 feet — you cover a huge area with fewer seams.
If your project covers a large stretch of land — a backyard slope, a long roadside bank, or a construction site — this Agfabric roll gives you 448 square feet of coverage in one continuous piece, which is nearly twice the area of the AK TRADING Co. blanket. At 36.5 pounds it is hefty, so a two-person installation is the smart move. The jute mesh has large enough openings for grass to sprout through, and owners mention it works well laid between soil and sod for instant lawn establishment.
One reviewer found the blanket shed a lot of loose fiber and described it as messy — the dust and bits get on clothes, which is note if you wear light-colored gear. Another said it is lightweight despite the roll weight, easy to cut with a utility knife, but needs to be nailed down securely to prevent shifting. For the price per square foot, this is the best value for covering a big area, especially compared to the Sandbaggy or AK TRADING Co. options that cost more per roll for smaller coverage.
Where it falls short is the lower customer rating (4.2 stars vs 4.5 for the top picks) — a minority of buyers flagged inconsistency in the weave or had issues returning partial rolls. For a straightforward project where you just want maximum coverage without buying extra rolls, this is the most efficient choice.
The big advantage
- 448 square feet per roll — the largest coverage in this roundup reduces your spend on multiple rolls
- Works as a base layer for sod installation or direct seeding on slopes
- Easy to cut and shape around existing plants
The messy trade-off
- Sheds loose fiber during handling — you will get jute dust on your clothes
- Heavy roll at 36.5 pounds — definitely a two-person job to unroll
Best for large areas: If you have a broad stretch of land to cover and value efficiency over per-roll durability, this blanket delivers the most coverage for the investment.
Not ideal if: you have a very small patch or need the densest, longest-lasting jute — the AK TRADING Co. or Sandbaggy blankets are heavier per square foot.
4. Agfabric Natural Jute Erosion Control 4x30ft
A denser, heavier jute at 13.6 oz per roll — built for the steep spots.
This Agfabric variation trades total coverage for density: at 13.6 ounces per square foot (400 GSM) across a 4×30 foot roll covering 120 square feet, it packs more fiber per inch than the longer Agfabric roll above. The higher density means it resists tearing on steep 30-degree or greater slopes where a lighter blanket might slide or rip. One buyer used it on a steep slope in Southern California, laying it down and covering it with mulch to prevent mud and rocks from sliding.
Customers note it works well as a burlap ground cover for garden beds and hillside stabilization — a second buyer used it to protect new seed from a puppy digging, and the sturdy jute held up to being reused after the first project. At 11.73 pounds, the roll is manageable by one person for a short slope or garden strip. The catch is the same as other short rolls: at 120 square feet of coverage, it covers half the area of the AK TRADING Co. blanket for a similar price, so the cost per square foot is higher.
Compared to the straw options lower in this list, the jute is significantly heavier and more durable — it will not shed fill material when cut into smaller pieces. This makes it a strong candidate for anyone who needs a compact, dense blanket for a tricky spot rather than a huge grassy field.
Why density matters
- 13.6 oz high-density jute (400 GSM) outperforms lightweight straw on steep slopes
- Light enough at 11.73 lb for one person to carry and install
- Buyers confirm it stopped erosion on steep grades even with mulch on top
Consider before buying
- Only 120 square feet per roll — you need multiple rolls for a large area
- Premium price per square foot compared to longer jute rolls
Grab this for: a targeted area like a steep garden slope, a new culvert, or a patch of hillside that needs a dense jute blanket until plants fully cover the ground.
Skip it for: covering a broad, gentle lawn — you will spend more per square foot than a longer jute or straw blanket would cost.
5. Farm Plastic Supply Erosion Control Blanket
The budget straw blanket that is 39 pounds of seed protection for your lawn.
If you are reseeding a flat or gently sloping lawn and want to keep the seed where you put it, this rolled blanket of agricultural wheat straw makes the job much cleaner than tossing loose straw. It covers 225 square feet (2 feet wide by 112.5 feet long), and at 39 pounds it is a heavy roll — expect a two-person install. Reviewers point out it protected grass seed from dogs, wind, and heavy rain, and the grass grew within a week, with one user noting it withstood monsoon winds and rain.
The single-layer construction means it is not as thick as the product photo suggests, but several reviewers confirm it is sufficient for erosion control on moderate slopes. The main weakness is structural: if you cut it into small patches to fit around plants, about 25% of the straw can fall out of the netting. One buyer specifically ran into this problem when trying to shape it around a garden bed. The blanket works best when laid out in one full piece — unroll it, pin it, and let it do its job without cutting it into small sections.
Straw is lighter-duty than jute, so it breaks down faster — typically within 6 to 12 months — which is fine for quick grass establishment. It retains moisture to help seeds germinate, shielding them from birds and the sun’s heat. For flat backyard reseeding, this is a solid budget-friendly option.
What it does best
- Excellent for protecting grass seed from wind, birds, and heavy rain during germination
- Straw retains moisture to help seeds sprout quickly
- Buyer reports grass grew within a week and blanket withstood monsoons
The catch to know
- Straw falls out if you cut the blanket into small pieces — use it in full strips
- Single-layer construction is thinner than the product photos suggest
Best for: reseeding a bare lawn or flat area where you want a simple, affordable blanket that keeps seed in place until the grass is tall enough to be mowed.
Not for: steep slopes or projects where you need to cut around many existing plants — the loose straw structure will shed material.
6. American Excelsior Company Premier Straw Erosion Control Blanket
A 4-foot wide straw blanket for fast grass — with some quality inconsistency.
This is the widest straw blanket in the list at 4 feet across, covering 200 square feet per roll (4 feet by 50 feet). It is designed for quick grass seed germination by holding moisture near the soil and keeping birds off your seed. American Excelsior has been making erosion control products since 1888, so there is a long history behind the manufacturing. Several buyers had success with it — one said it stopped runoff from a sloped side yard, holding topsoil in place until the grass grew in.
The mixed reviews (3.8 stars out of 5) point to the main risk: the blanket’s density varies from roll to roll. One buyer wrote that the product they received was very thin and mostly plastic netting with very little straw, calling it a waste of money. Another said the mat density is suited for barren ground but not for rich topsoil. The bright side is that multiple users confirmed the included stakes were enough to secure it on their slopes, and the grass grew super thick after installation.
Compared to the Farm Plastic Supply straw blanket (2 feet wide), this one is wider, which means fewer strips to overlap on a wide area. But the inconsistency in straw density makes it a gamble — you might get a thick blanket or a thin one. If you prefer a guaranteed jute density, the Agfabric or AK TRADING Co. rolls are safer bets.
Potential upside
- Wide 4-foot coverage reduces seams and overlapping on larger slopes
- Shoppers say it stops runoff and held topsoil in place until grass grew
- Long-established manufacturer (since 1888) with field experience
Downside to watch
- Inconsistent straw density — some rolls arrive thin with mostly plastic netting
- Lower customer rating (3.8) reflects frustration over quality control
Worth a try if: you are on a tight budget and need a wide, fast-deploying blanket for a gentle slope, and you are willing to roll the dice on density consistency.
skip it if: quality variation frustrates you — the jute options above cost more but deliver reliable density every time.
Understanding the Specs
GSM (Grams per Square Meter)
This is the standard unit for measuring the density of a jute or straw blanket. Think of it as how tightly packed the fibers are — a 400 GSM blanket, like the Agfabric high-density jute, is heavier and more durable than a typical 200 GSM blanket. Higher GSM values mean the blanket holds up better to heavy rain and lasts longer before breaking down. For a steep slope, aim for a higher GSM; for flat areas where grass grows quickly, a lower GSM is usually adequate.
Stitch-Bonded vs Woven
A stitch-bonded blanket has its fibers mechanically sewn together with thread, which helps the material stay intact even when cut. The Farm Plastic Supply straw blanket uses stitch-bonded construction with agricultural wheat straw. Woven jute netting, on the other hand, is made by weaving fibers into a mesh with regular gaps — this lets plants push through easily while holding the soil. Woven jute tends to be more durable for long-term stabilization, while stitch-bonded straw is a better fit for quick temporary use.
