Where to Use: This seed is perfect for starting a new lawn from scratch or for thickening up an existing one. It grows best in areas that get a good amount of sun.

How to Use: Use it to start a brand-new lawn or to overseed the one you've already got.

When to Use: The best time to plant is in the spring or fall when temperatures are consistently between 60°F and 80°F.

How Often to Use: For best results, overseed your lawn with this product once a year to keep it thick and healthy.


For a New Lawn:

  1. Get the Ground Ready: Grab a rake and loosen up the top couple of inches of soil, clearing out any rocks or dead grass.
  2. Spread the Seed: Pour the product into your Scotts spreader, dial in the ""New Lawn"" setting, and apply it evenly.
  3. Gently Tuck it In: Lightly rake the seed into the top layer of soil. You just want it barely covered.
  4. Give it a Drink: This part is key. Water daily (or as needed) to keep the soil moist until the new grass is at least 2 inches tall.

For Overseeding:

  1. Get Your Lawn Ready: Mow your lawn nice and short (about 2 inches). Then, give it a good rake to loosen the soil and clear out any dead stuff.
  2. Time to Spread: Fill up your spreader, set it to the ""Overseeding"" setting, and walk at a steady pace to get even coverage.
  3. Just Add Water: Water every day, or as needed, to keep the soil damp until the new seedlings are at least 2 inches tall.

New Lawn:

  • Scotts Broadcast/Rotary Spreaders: 6 ½
  • Scotts Hand-Held Spreaders: 5 (2 passes)
  • Scotts Drop Spreaders: 16
  • Scotts Wizz Spreader: 5
  • Scotts Elite Spreader: 5 ½

Overseeding:

  • Scotts Broadcast/Rotary Spreaders: 3
  • Scotts Hand-Held Spreaders: 4
  • Scotts Drop Spreaders: 9 ½
  • Scotts Wizz Spreader: 3 ¾
  • Scotts Elite Spreader: 3 ½"

You'll want to water the newly seeded area every day for at least three weeks to keep the soil surface moist. This is the most important step for success. An automatic timer can be a real game-changer here, making sure you don't miss a watering.

  • Let it Grow: We know you're eager to mow, but let the new grass grow until it's at least 2 inches tall before its first trim.
  • Keep it Fed: To keep that awesome new lawn looking its best, give it a good meal every 8 weeks with a Scotts Lawn Food product.
  • A Note on the Seed: We've treated the seed with a fungicide to protect it from disease. Because of this, it's not meant for food, feed, or oil.
  • Store it Smart: Keep any leftovers in the original bag and store it somewhere cool and dry, away from kids and pets.
  • Keep it Tidy: If any product ends up on your driveway or sidewalk, just sweep it back onto the lawn. This helps keep our local waterways clean.

Frequently Asked Questions

How do I store leftover product?

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

It's the go-to for a classic, beautiful lawn. It grows a really dense, dark green turf, and it's tough enough to stand up to everyday wear and tear.

Kentucky bluegrass takes a little longer to get going, so be patient. With proper watering, you should start to see the first green sprouts in about 14-21 days.

This mix really loves the sun. If you have a lawn with a lot of shady spots, you'll get better results with our Scotts Turf Builder Grass Seed Sun & Shade Mix.

Rated 5 out of 5 by from Scott shipping Shipping was a reasonable time. Much better than order that was shipped September 5 and I’m still waiting for delivery.

Rated 2 out of 5 by from Undesirable light green color This product is 100% Bluegrass (4 different varietals), however it seems to be a much lighter green than Bluegrass I've grown before. This product also produces a grass with very thin and whispy blades of grass that get tangled up and mat down too easily. I have taken a few pictures two of them show some bare spots that I seeded last fall, Fall of 2024; it is now June 2025. In a way I feel it grows too densely. The patches are distinctly much lighter in color than the old bluegrass lawn which surrounds it. Two months ago (in 2025), as controlled experiment I grew some of this product in a small pot. One can see the thin, tangled blades of grass up close; they are undesirably lighter than other bluegrasses that I have used in the past.

Rated 1 out of 5 by from Unhappy with results I’ve bought Scott’s Bluegrass seed for many years with good results but after second time of poor results I’m done with it. Not cost effective nor do I like wasting my time to grow mostly weeds. Last year I had a beautiful lawn but my lawn wasn’t looking as plush so I seeded my entire yard and this year I have a wide bladed ugly grass taking over that I can’t get of. This year I filled in some low spots, seeded with Scott’s Bluegrass Seed Mix and more weeds and crabgrass growing than should be if only 1% of seed is weeds. I’ve pulled weeds twice now from the areas and again the areas are full of weeds and crabgrass. Before submitting I seeded a small area with prime top soil vs pulverized dirt, same results.

Rated 1 out of 5 by from scotts blue grass I put down grass seed covered with pear moss and watered it 2 times every day .About a third came up and doesn't seem to be growing taller even tho I am still watering every day . I am not very satisfied

Rated 2 out of 5 by from Not worth the money, doesnt work I dethatched my yard, scarified it. Put down the seed and put peat moss over it with a roller. Watered exactly as instructed and not a single blade of grass can be seen after a month. The spots where I tossed the seed down without any care or prep, growing like crazy. $300 in materials and time totally wasted.

Rated 1 out of 5 by from Used to love (GREEDY) I use to love Scott's blue grass seed and Scott's rye grass seed, I use to buy both and of course Scott's starter fertilizer. I use to reseed every 2. 3 years for about 50 yrs Now I most use another brand because Scott's wants to be greedy and make all their grass seed combination of seed, fertilize and soil improvers. ALL their grass seed. I looked high and low, everywhere, just these weighted down bags with less seed and soil improvers. Why couldn't you make both. So I had to buy Jonathan Green.

Rated 5 out of 5 by from Easy to apply ! This stuff works great. I recently added a water line for my rose bushes. Then when I bought some topsoil I mixed this right in the bucket with my fresh dirt and laid a nice layer right on top of the lawn and within 2-2.5 weeks being patient and watering on the regular it filled it like it was never disturbed. I was happy to see weeds didn’t come in and it was only good grass
