Key Features

  • THE 3-IN-1 SOLUTION FOR THIN LAWNS: This all-in-one mix has it all - seed to fill gaps, fertilizer for thicker, greener grass, and a soil improver to build stronger roots
  • GET UP TO A 50% THICKER LAWN*: Just one application is all it takes to get you on your way to a thicker lawn
  • STRENGTHENS & PROTECTS: This mix does more than just thicken; it improves your soil, building a strong root system to help your lawn stand up to stresses like heat and drought

*Subject to proper care. Results may vary based on current condition of lawn.

A thin, weak lawn can be a real bummer. But getting it back to its thick, green glory doesn't have to be complicated. Scotts Turf Builder Thick'R Lawn Tall Fescue Mix is the simple, all-in-one solution you've been looking for. We've combined three essentials into one easy-to-use product. First, there's the seed, which fills in those thinning areas and gaps. Then, we added fertilizer to give both new and existing grass the nutrients they need to grow thicker and greener. Finally, there's a soil improver that enhances root development, creating a stronger foundation for your lawn. It’s a straightforward, three-pronged attack that will get you a lawn that's up to 50% thicker (subject to proper care, results may vary based on the current condition of your lawn).

Where to Use: This is for your whole lawn, and it's a real hero on those thin, struggling areas.

Where Not to Use: Steer clear of applying near water, like storm drains or ditches. And it's best to hold off if you've got heavy rain in the forecast.

How to Use: This is your go-to for thickening up a thin lawn.

When to Use: The sweet spot for applying is in the spring or in the late summer/early fall.

How Often to Use: For a truly top-notch lawn, we recommend applying once in the spring and again in the late summer or early fall.

  1. Get the Lawn Ready: First things first, mow the lawn down to about 2 inches. Then, grab a rake and give it a good going-over to loosen up the soil and clear out any old, dead grass.
  2. Time to Apply: Pour the product into your Scotts spreader, set it to the right number, and take a steady walk across your lawn to make sure you get nice, even coverage.
  3. Just Add Water: This part's a biggie. For the first two weeks, you'll want to water every day (or as needed) to keep the soil moist. This helps the new seeds get their start. You can get back to your regular mowing routine once the new grass is tall enough.
  • Scotts Broadcast/Rotary Spreaders: 9 1/2
  • Scotts Hand-Held Spreaders: 5 (3 passes)
  • Scotts Drop Spreaders: 14 (2 passes)
  • Scotts Wizz Spreader: 5 3/4 (2 passes)

Don't be shy with the water for those first two weeks. Keeping the soil consistently moist is the secret to getting those new seeds to sprout. Think 'damp,' not 'drenched.' Once the grass is established, you can cut back.

  • Know When to Go: You'll get the best results if you apply this in the spring or late summer/early fall when the weather is just right.
  • Give the Mower a Break: Let the new grass grow until it's as tall as the rest of your lawn before you mow it for the first time.
  • Handling Bare Spots: Got some really empty patches? For those, we'd point you to Scotts EZ Seed Patch & Repair. It's made just for that
  • Heads-Up on the Seed: We've treated the seed with a fungicide to protect it from disease. Because of that, it's not meant for food, feed, or oil.
  • Store it Smart: Keep the bag in a safe place, away from food and out of reach of children.
  • Keep it Tidy: Use a broom or blower to sweep any granules that land on your driveway or sidewalk back onto the lawn. It helps keep our waterways clean.

Frequently Asked Questions

How do I store leftover product?

Got some left over? No sweat. Just keep it in the original bag in a cool, dry spot like the garage or shed, safely away from kids and pets.

You'll start seeing that hard work pay off in about 2-3 weeks, as long as you're giving it the proper care. Every lawn's a little different, so your results might vary depending on where you started.

This product is really meant for giving a boost to a lawn that's already there but just a bit thin. If you're starting a whole new lawn from scratch, you'll want to grab one of our Scotts Turf Builder Grass Seed products instead.

For the first two weeks, you bet. Keeping the soil consistently moist is the most important part of the job. It's what wakes up the seeds and gets them growing.

Rated 5 out of 5 by from Grass Can Grow in Spring I planted this seed in late Spring, as there was a bare spot that I wanted to cover before summer. Typically I plant grass in the fall. Although it took a bit longer than I expected to grow in, I am very pleased with the results and the grass has withstood some stress and heat this summer. I was meticulous about following the preparation steps prior to planting and the grass eventually grew thick and tall as advertised. I would purchase this product again.

Rated 5 out of 5 by from Will give you great looking grass We decided to use this product in our side yard that tends to get a lot of shade from our neighbors tree. This has helped fill in the area and it is a nice dark green lush grass with very little weeds.

Rated 5 out of 5 by from Best Yet I used the Scott 3 in 1 and grass last year after cultivating and redoing my yard. I add topsoil grass seeds along with 3 in 1 cover it with EZ Straw. This year in March my grass has never look better and look at it now. On May 12 I will be used the Scott Turf Builder Lawn Food. I highly recommend this product. Will be using it in early Fall.

Rated 5 out of 5 by from Great Product Scott's products are easily one of the best on the market. When I used the grass seed with fertilizer it grew and filled in all the areas that didn't have grass. They also stand behind their product. I will continue to use their products as does all my family. Thank you for making such a great product.

Rated 5 out of 5 by from Surprising Results My lawn is a seeded lawn not sod. Thus, it's been a laborious effort to develop it into a beautiful setting. I've had numerous bald areas and much weeds and clover. My plan has been to energize it by applying the Thick'R Lawn product as a phase 1 step. Would follow-up in a few weeks with the Weed & Feed. After a season opener mowing, I applied this product. 3 weeks later, it grew very thick, tall, and heavy. Mowed it and saw the real results. Lush, rich, deep green lawn!! almost 100% coverage of the bald areas. I'm highly satisfied that my base lawn condition has emerged. My area is approximately 3/4 acre. Employed 5 bags (5,000sqft each). This was worth the expense and effort. I'm anxious to move to the next phase (Weed & Feed) to strength it and create more beauty!!

Rated 5 out of 5 by from Unbelievable Results Bought Thick'RLawn expecting average results and the lawn I now have is the best it has been in years. Watered everyday using my sprinkler system for 2 minutes and it's greener and thicker than anytime before. Highly recommend!
