Use this product to overseed your lawn once in the late spring and once in the late summer or early fall.

    • Lots of annual grass seed.
Size: 40 lb.
I spread this last summer and lawn really greened up but this spring there are dead spots. I read the label and saw it contained lots of annual grass seed. I had to overseed with a perannial grass seed. It's good for 1 year but be ready to overseed the second year.

    • Transformative Lawn Care All-in-One!
Size: 40 lb.
As a homeowner, I've always aimed for the perfect lawn, and the Scotts Turf Builder THICK'R LAWN Grass Seed, Fertilizer, and Soil Improver has made that goal achievable. This 40 lbs. bag covers an impressive 4,000 sq. ft., offering a comprehensive solution for lawn care that's hard to beat. First, what sets this product apart is its multifunctionality. It combines grass seed, fertilizer, and soil improver all in one, simplifying the lawn care process. It's suitable for both sunny and shaded areas, making it versatile for various parts of your lawn. The grass seed component is impressive. It's a mix of premium grass varieties that have thrived in my yard, filling in patches and thin spots, creating a lush, green carpet of grass. I was thrilled to see how quickly the grass began to grow and how much thicker and healthier it looked within a few weeks. The fertilizer and soil improver are equally essential. They nourish existing grass and provide a rich foundation for new growth. My lawn's color improved noticeably, and it became more resilient to foot traffic and environmental stressors. Application is straightforward, thanks to the detailed instructions on the bag. I used a spreader, and it distributed the product evenly. Watering it in afterward helps activate the seeds and nutrients effectively. I appreciate that this product is backed by Scotts, a trusted name in lawn care. It's clear they've invested in research and development to create a formula that works wonders. While the initial cost might seem higher than just grass seed alone, the convenience and results it delivers are well worth it. In summary, Scotts Turf Builder THICK'R LAWN is a game-changer for anyone seeking a thick, healthy lawn. It's efficient, easy to use, and delivers remarkable results. If you're looking to transform your lawn, whether in the sun or shade, this product is the answer you've been waiting for. I couldn't be happier with the results, and I highly recommend it to all lawn enthusiasts. ... show more

    • Good Soil Amendment - Better Options Exist for the Midwest
Size: 12 lb.
I started using Thick'r about five years ago and really enjoyed it. The more and more I've gotten into lawn care the more I've realized that there are better ways of getting this result (buying soil amendments like lime and biochar separately, better grass seed, organic fertilizer like Milorganite). Biggest issue I have is the rye blend they use with the grass seed. It looks great but cannot handle midwest summers. Product works and the grass does thicken up - great for beginners - but I'm giving it 3 stars as you can make a similar blend at a much more cost effective price point that simply works better. ... show more

    • Nothing grew. 4.8 lbs of total grass seed in 40 lbs bag

I purchased this hoping it would fill in some bare spots and areas that were thin. I had first dethatched my lawn and then scarified it as well preparing the soil as best I could for the seed. I had delivered from a landscaping company their best lawn soil mixture. I purchased a lawn leveling rake so I could level the lawn from some low spots. I went ahead planted the seed with the fresh soil and leveled the lawn. Kept it watered and in over a month now zero nothing not a blade of grass. I had only used 1/2 of the bag because the area I was covering was around 1000 sq feet and the bag says up to 4000 sq feet so I was planning on reseeding in the fall. It’s laughable to think 4.8 lbs of grass seed will cover 4000 sq feet of lawn when on average they recommend 4-7 lbs per 1000 sq feet for over seeding. So I wasn’t even using half of the recommender area and half the bag so I was well covered. So after a couple weeks I decided I would try a old trick of putting grass seed in my wheelbarrow and grow it under optimum conditions. I went and purchased SCOTTS LAWN SOIL FOR SEED. Keep it in the family I thought. Can’t blame the soil If it’s their own I went and mixed up a co side table amount of the product with the soil In my wheelbarrow. I watered it and covered it and put in my shed. I monitored it every day and then I decided to bring it out in the sun when the temps went up. It was easy to keep it moist. I have a raised bed vegetable garden a Hosta garden so I am an avid gardener. I love plants and gardening. I have Window boxes I grow flowers in every year so I’m not some rookie who doesn’t understand how grass grows. Grass needs warmth, moisture and direct contact with soil. That’s it the seed will do the rest as it has all it needs to sprout. Keep it moist warm and in contact with soil. Why the wheelbarrow is a great place to jump start seeds. It’s been 18 days and not a single blade of grass. This seems almost impossible unless this bad had no grass seed in it at all. Idk but I looked on the bag and here is what’s included. 3.68% Alloy Perennial Ryegrass 3.62% Vision Perennial Ryegrass 1.85% Bolster Chewings Fescue 1.75% Boreal Creeping Fescue .61% Starr Kentucky Bluegrass .61% Dauntless Kentucky Bluegrass Other ingredients: 87.81% Inert Matter .06% Other Crop Seed .01% Weed Seed This comes to 12.1% Seed 4.8lbs 87.88% Inert Matter 35.15 lbs Total 40lbs So they expect us to believe 4.8 lbs of grass seed can fill in your lawn of 4000 sq feet? And if I called and asked them how much grass seed would I need for 1000sq feet I would be told 4-7 lbs to overseed it. So in this bag they put in little seed and tell you it covers 4000sq feet but if you buy straight grass seed you need as much as 7 lbs for 1000 sq feet? Something isn’t right. So I am done with Scott’s grass seed. There so called guarantee. Guaranteed you will look to another company for your lawn care products after using ours. ... show more
