The 5-oz. MegaGrow (20 yr) Weed Barrier is a polyester-blend polypropylene landscape fabric that works to keep weeds out and hold moisture in. Its breathable design allows for the application of water, fertilizer, or insecticide over the top of the fabric. The liquid will filter down into the soil without damaging or degrading the fabric itself. The MegaGrow Weed Barrier can be cut to size using household scissors. In most applications, the MegaGrow Weed Barrier should be installed fuzzy side down, which will provide the best results for weed control and soil stabilization. However, when mulch is being placed over the fabric, installing it with the fuzzy side up will help hold the mulch in place.

Greenhouse Megastore is the exclusive distributor of 5-oz. MegaGrow Weed Barrier which allows it to be shipped and sold for a lower cost than other landscape fabrics.

  • CEO Nursery
    Love the product... i replaced all my weed barrier with this product.
  • Reviews are not completed until 5 years of use
    Looks pretty, now wait five years for my review, so it will be relevant. Only users over time can accurately review merchandise.
  • Not 250 feet long...just 100 feet
    8/10 - I ordered the megagrow weedblock roll that was 3 feet by 250 feet. What I received was only 100 feet.long. I am hoping they will send me the balance. Contacting them now. Stay tuned.
  • disappointed
    It's supposed to be a heavy duty weed barrier with a felt-like backing. I've used Dewitt before and they truly have a thick felt backing. On this product, the felt backing was so thin that is wasn't even there in many spots - you could see right through to the woven top-layer. What's the point of paying for a thick, felt backed product when the felt is almost lacking making it a less rugged and an overall thinner product than it should be. Truly disappointing. If I hadn't needed this for an immediate project, I would have sent it back. Next time I'll pay the extra and go with Dewitt. I suggest if your looking for a heavy-duty, felt-backed product, go with Dewitt.
  • Pretty good
    The product is quite good, Not as good as the $150 Dewitt but so far I have no weeds coming through.
  • Great product Great price
    We use this in our berry patch and in the corn patch. Holds up well and easy to put down. They were out of stock and I purchased from a competitor for a higher price but it’s not as good.
  • Quality weed blockage here
    I just got done laying my MegaGrow weed blocker down around my small orchard and I'm impress with the quailty of material this blocker is my out of. It feels thick enough that my John Deere lawnmower doesn't tear driving over it on occasion when feeling lazy driving around the outside of my my field of fruit and bonsai trees.
  • Using under my beds
    I bought this product to lay under the area I placing my veg. Beds. I plan on covering it with multch. I live in Florida and we have a lot of weeds. Quality looks great. Cannot wait to get started
  • Seems good quality
    Fabric looks and feels good. I did a You Tube video on the 4 foot wide fabric. Hope this helps. https://youtu.be/XHrw3ZkPKTU
  • works as advertised
    keeps weeds down lets water pass
  • ground covering
    this is a great product if you want to block out weeds and grass. I have used it for years and it has never let me down yet
  • farmer
    first year using the product
  • Other uses
    I'm using the 5 oz MegaGrow (20 yr) Weed Barrier as a sight barrier/privacy fence. Attaching it to the chain link fence so my two dachshund and jack Russel are not tempted to bark at every single thing. Made the neighbors happy. Giving a 4 because 20yrs hasn't gone by yet.
  • Greenhouse ground cover
    This is truly the best ground cover for greenhouses. I have been using this for year with get results for total weed control.
  • weed barrier
    worked well, just what I needed
  • Good Product
    So far so good! Very durable product and easy to roll out. Clip stakes are substantial. Best price I could find too!
  • Retired Rob
    Great product,great value!!!
  • Order not complete
    We received the order minus the 72 pins that came with price. Very disappointed. As for the cloth, easy to lay out and heavy enough with minimal weight to stay put. Will see if works.
  • Solid Product_Timely delivery
    The online order was sketchy, as there wasn't a confirmation of the transaction; however, the product was delivered two days earlier than projected, and the 5ML weed barrier was of good quality. The weed barrier was exactly as advertised. I will buy more of this product in the spring from this retailer. Very pleased.
  • changes
    I purchased a couple rolls of this fabric last year (3' & 4' wide). I noticed that it was different in the roll I purchased this year. The first rolls had a softer top surface while the latest is a slippery plastic surface. Still tough & heavy but prefer the softer surface for my walkways between garden rows.
  • Weed Barrier
    5 oz MegaGrow (20 yr) Weed Barrier - 8' X 250' roll was great, very stong and at a great price. I needed to cover 1200 sq ft of plant area for color stones. did not bother with anchoring pins, just put the barrier down then the rocks as I went.
  • third roll and this was for a friend
    bought first roll three years ago. covered with chips and is still going strong. the second was an xmas present for a friend with a greenhouse. i am rating a third roll because we are expanding the garden. price was excellent. shipping was fast! be sure to get the landscape pins. a good deal and more convenient than making your own (i know).
  • Mr homeowner
    Product looks good, was installed last weekend. I expect it will keep the weeds down in the ditch it was installed. About two inches of crushed rock on top.
  • 5 oz 12X250 weed barrier with pins
    excellent product for weed control--do not cover with mulch unless you want weeds in a year or 2 as mulch eventually promotes weeds
  • Quality plant protection
    I bought this material so I will NOT have to weed the garden this year. This fabric is much heavier than I expected and should hold up well for several planting seasons. I plan on covering the outer edge with dirt to hold it down. The price was well worth it for the amount I ordered. 250 feet will handle several rows for me. Thanks for a good quality product.
  • ez to work with
    a good size for all kinds of projects. marked for cutting. durable. shipped quickly
  • only way to go
    We love this product and use it for walkways and preping beds for the next year. and as an underlayment for our water features including the water wheel and waterfalls.
  • good for the price
    I bought this to be reusable for field crops on plasticulture. One of the main reasons I picked this product was it had 1 ft marking lines. I just burned 1000 holes through the fabric for plant holes and the preprinted lines were of almost no help. Lines do not correspond to the side of the fabric and vary from roll to roll. BUT it should keep weeds out. IMO why have lines at all if they are inaccurate ?
  • ok but lesser quality
    i have purchased this weed barrier and the dewitt brand. The quality of this product is not the same. the felt backing seems to be stuck to both sides and the backing material seems thinner. i bought because the shipping was free. If i had a critical application i would make another choice. Having a product that does not perform would be very costly. I am very happy with the seller and will continue to purchase other products from them. they are a first rate merchant and handle items that i have not been able to find elsewhere
  • Great products
    Greenhouse Megastore is a great place to shop, place 3 different orders with no problems other than 1 item was on back order and I really couldn't wait so called them up and they found me a suitable substitute with no delay in my project. Highly recommend their product and customer service.
  • quality product
    Fairly light compared to others I have used but then the price is very reasonable. It seem to be a very good product so far for the price. I would recommend it.
  • Ground cover cloth.
    This cloth does the job. Worth every penny on setting up flower beds or other landscape features. Easy to cut and lay out. Put down almost 200 sq. ft. Great product.
  • Great stuff
    This works like nothing else we have used. this is our 2nd roll and we will be buying a 5' roll next.
  • great product
    This is the one to get, 20 year warranty, free shipping and comes with staples. Product has slick and rough side and you can choose which way to install, depending on what you need. Looking forward to 20 years of weed free life!
  • FAB fabric
    Great quality for a good price. Can't be beat to help control weeds and grass where they aren't wanted.
  • Great stuff
    Easy to use and works great makes our dry creek easy to put in.
  • Great customer service
    Was missing the pins for weed paper and they sent them right away. Great service. Thank you!
  • Property Team Head
    Easy to apply. Looks great
  • Great soil fabric
    I have used multiple rolls for community garden paths and public wayside planting. No weed has penetrated the fabric, but it allows water and air to pass easily. Worms are plentiful below it. Very pleased with the results and durability.
  • Great for a Dog Show!
    Our Kennel club used this cover to put on agricenter dirt to keep dog hair out of it. It held dup great with wire dog crates and dogs and people walking all over it for the weekend. It is now stored and we plan to use it for 5 or 6 more years.
