Does Not Work
I bought this product to repair lawn damaged by Fall army worms. I treated the worms a month before using this product and as you can see from the photo after 3 to 4 weeks of keeping the soil damp, there is still no new grass.

Jpm4, we're sorry to hear Scotts Turf Builder Thick'R Lawn didn't perform as expected. For best results, day and nighttime temperatures should be consistently between 60-80 degrees. Contact us at 877-220-3089 for assistance with our product guarantee. Scotts
    The easiest grass I ever planted!
    I was amazed, I put this down in the spring. I watered less than they suggested, but it came up within a week, was beautiful in 3 weeks. It will be the only thing I will use in the future!!

    Spreads & covers well, easy to see once on ground
    [This review was collected as part of a promotion.] First, I feel thar the sizing of this bag is perfect for smaller areas that need a little extra love and attention. It spread very well in my push spreader, and we are excited to see the difference this product makes to a yearly troubled patch at our property. I also liked how easy it was to see the product as it spread, and afterwards, making it easy for me to see if I had missed any areas. I cant wait to see how much of a difference this will make to our lawn, and anticipate purchasing more if all goes well. The bad itself had an easy to open top, with a small indication notch to pull away. The sizing was just right for what we needed, and looking online the price point is where I would expect this to be.

      Great product
      [This review was collected as part of a promotion.] This is a great 3 in 1 product to use that will help thicken your lawn. It contains seeds, fertilizer, and soil improved to help with root development. It can be used in both sun and shade. This product produces up to 50% thicker lawn. It is the easiest solution for filling in a thin law .
        good product
        [This review was collected as part of a promotion.] Received the Scotts Turf Builder Thick’R Lawn Sun and Shade the other day. I like that it has everything you need to help turn weak, thin grass into a thick, green lawn. I like the 3-in-1 solution for thin lawns, including seed, fertilizer and soil improver. I applied this to several dead spots in my yard. I put straw down so that the birds would not eat it. I checked a small section and am glad to report that I have some grass sprouting. I am hoping it will continue to grow before it turns any colder here in SWVA. It was easy to apply and seems to be doing a good job.

          Filling in bare areas very nicely….impressive
          [This review was collected as part of a promotion.] This is a unique all in one seed & fertilizer product which is great to reduce work and keep the lawn looking green and lush. This is my new go-to product to thicken up thin areas and fill-in where the lawn is bare. It works really well and the seed grows quickly. I like that this is a three in one product with the seed, the fertilizer and even the soil improving ingredients. There will always be a problem areas that need to be re-seeded but I need to keep it effective & fast so I can get to other chores. I recently had to have some interior/exterior water pipes replaced and they had to dig up part of my grass. I was able to fill it in fast and quickly get the grass regrowing and the bare spot covered.

              Little work once it comes in enough
              I bought Scott’s Sun and Shade because of the location (behind the garage) I wanted to fill in. I used both the bag seed and compost to start and watered every day for about two weeks. I’m please with how well it came in and only have a few patches I need to go back and fill.

                Applied at 2X coverage, see pics!
                I moved into a new construction house with a garbage lawn (1/2 acre) and am working on small sections at a time. The bag says this covers 4,000 square feet but that’s a lot of watering to keep up with every day for 3 weeks. My lawn was bad enough that I decided to apply the whole bag to just 2,000 square feet for double coverage. The pictures tell the story - taken exactly 3 weeks after application and watered 19 out of 21 days. I have another 2,000 square foot section I’m tackling next but I plan to mix additional seed with the THICK’R LAWN product to better fill the bald spots. I will also be applying an entire bag at double the rate (4,000 sq ft of product in a 2,000 sq ft area). I should also note that this was from June 18 - July 9, in Southern PA; not exactly the best time to grow grass but I kept up with the watering and it did well in spite of the heat.

                  We are sorry that the germination rate of your Scotts Turf Builder Thick'r Lawn Sun and Shade was unsatisfactory. There are a variety of factors that play a role in successful germination, and if even just one of these factors is not right the germination of the seed can be affected greatly. As a reminder this product is only designed for overseeding projects and will only produce sparse growth on bare areas. Here at Scotts, it is always our goal to produce the highest quality products and we stand by the promises made in our advertisements. When a product does not function as it should, we want to hear from you in order to improve our services. For this reason, we offer a product guarantee to our consumers.
