This is probably the worst product that I ever bought in my many years of shopping at Home Depot and doing yard work. it's a complete waste of your money. It won't help grow your new grass seed, even when watered faithfully. Six weeks later it's stuck to the ground and blowing around the yard after I finally ran the mower over to try to get rid of it. It's totally a worthless product. Stick to hay / straw to cover you new grass seed.

    Worked for me
    It’s been about 2 weeks and lots of heavy rain. Although some of the grass is growing underneath. Well see what happens.

      Avoid patchy growth: Read this first.
      Just did a reseeding project on a 16’ x 3-4’ patch. First time, so I did a lot of research on videos and websites, from Scott’s to YouTube lawn care guys to try to find a consensus on how to “do it right.” When using this seed mat, this proved to be a mistake. Started first week of September, did appropriate ground prep, and put down Scott’s Lawnstarter soil. Put Scott’s sun and shade seed, and applied starter fertilizer. So far, so good. My error was adding the thin layer of Lawnstarter soil 1/8” on top of seed. Maybe it was the light raking. I dunno. I later found people wishing they hadn’t done this since it is too easy to add a little too much soil and bury the seeds, and just too hard to consistently keep a light layer. Ditto for peat moss. At any rate, looks like you can get a patchy growth based on areas with too much coverage. Seems obvious to me now, but this mat means you *don’t need any further layer*! If I could do it again, I would spread the seed evenly over the entire soil, then maybe lightly walk on soil (or use a roller?) to gently press seed into soil. Then spread the starter fertilizer next as per directions. Then apply the mat directly on to soil. You do need to initially use a shower hose to ensure the entire mat has been soaked enough to secure it so soil. Then twice a day watering maybe just 10-15m to keep soil moist for at least first few weeks. It’s pretty cool to see the growth pop through, but disappointing to see those bare patches and know exactly why. I’m pretty sure that extra layer business it to keeps seed secure and not eaten by birds, but the mat will already do this. (Personally I don’t buy the “mat choking out new grass” theory. I’d be willing to bet those folks may also have thrown an extra layer or raked in a way that left the seed distribution really erratic. Like me). Here’s some weekly time lapse pics up to my first cut this weekend. Hope this helps somebody.

        Never degraded.
        Liked at first because seed under mat sprouted but then it became dense and choked out everything including weeds. The seed I planted outside the mat grew.

          The mat rolled out easily over the grass seed, even on our little hillside. Seeds sprouted and grass is growing nicely up through the Pennington seed starter mat. Completely satisfied with my purchase!

          Three weeks!
          I purchased enough to try an area due to the price but with seed starter and a good seed its great. I planted over red clay and the left side is the mat i put down over the area i did not three weeks ago.

            Works great if you know what youre doing!
            Bought this to cover brand new seed and it completely did the job! Soaked it after puttung it down and never had an issue with it coming up. It is a little pricey, but its worth every penny!

              Totally Works, Especially on Slopes
              Like anything, the prep work os essential. After cultivating (2”) and adding some quality topsoil, I seeded and used this mat to keep seed in place on my slightly sloped, small front yard. 4 rolls were used for this area, and I found it easy to work with once I got comfortable with it’s texture. I used a high quality, shade fescue seed and watered it 2x each day for a week. I left town for a 4-night work trip and was worried about not being able to continue watering per the instuctions for the seed. Long story short, I came home last Friday morning and found the results attached in the photo. I’ll recommend this to anyone starting a new lawn.

                Easy to install. Keeps the seed moist (if you water as recommended). Protects the seed from washing away. I highly reommend the product. We have grass growing through the green mat less than one week after planting the seed!
