How Often to Use: Wait at least 2 months between applications.

Unlike some of our other Weed & Feed products, this one needs to be watered in right after you apply it. Give your lawn a good watering to wash the granules from the grass blades and get them down to the soil.

  • Mow First: For best results, mow your lawn a day or two before you apply.
  • Don't Overdo It: If you've recently used another weed control product on your lawn, wait at least one month before applying Bonus S.
  • Let it Dry: It's best to have the lawn to yourself during application. People and pets can re-enter the area after the granules have been watered in and the grass has dried.
  • Dress for the Job: We recommend wearing a long-sleeved shirt, long pants, shoes, and socks when applying.
  • Wash Up: After you're done, be sure to wash your hands thoroughly with soap and water.

Frequently Asked Questions

How do I store leftover product?

Got some left over? No problem. Just fold the top of the bag down, secure it, and store it in a cool, dry place like your garage or shed, safely away from kids and pets.

Southern grasses are a different breed, and they have different needs. We formulated Bonus S to be effective on tough Southern weeds while being safe for grass types like St. Augustine and centipede, which can be sensitive to other weed control products.

Yes, this is a must-do. Watering immediately after application activates the product and moves it down to the soil where it can get to work.

You'll see weeds start to show signs of dying within a week or two, but it can take up to 5 weeks for some of the tougher ones to be completely gone.

Rated 4 out of 5 by from Rid the weeds! Still a little early to determine the effectiveness of the weed and feed. I have used Scotts products almost exclusively over the years and have been satisfied. This property is new to me, so there is much work to do.

Rated 1 out of 5 by from Loyal Scotts user has Lawn decimated We use Scotts products for decades , they have been our only source of lawn support and care. We now live on the NC coast from Long Island. We had to install St. Augustine at the water because of the environment , Dollar Weed has taken root . We went to Scotts Turf Builder Bonus S Southern Weed . Used exactly as directed. It's killing my Augustine NOT the Dollar Weed. It was also used on our centipede which is fine. see pic's

Rated 1 out of 5 by from Doesn't kill the weeds Scott's products have gone down hill over the last 4 to 5 years. I applied Bonus S Southern Weed and Feed to my established centipede yard and has not killed any of the weeds this year. Grass is green and so are the weeds...Not happy at all!

Rated 1 out of 5 by from Don't waste your money This product is ineffective against dollarweed. I recommend avoiding this purchase; Lowe's product quality appears to be declining
