The Scotts Miracle-Gro Company manufactures a line of products designed to promote lawn grass health with fertilizer while simultaneously killing lawn weeds. The company's "Bonus S" weed and feed products and Southern Triple Action mainly target post-emergent weeds, meaning weeds that are already growing in the yard. The company also makes weed killers for pre-emergent weeds. Generally speaking, weed-and-feed products don't eradicate crabgrass because you apply them too late in the season. Some weed-and-feed products may need second or third applications to achieve maximum fertilizer and weed-killing success.
Bonus S Southern Scotts Weed and Feed
According to the company's web pages, Bonus S Southern Scotts Weed and Feed fertilizes the lawn to strengthen the grass, providing better tolerance of both heat and drought. The slow-release fertilizer with weed control covers 5,000 or 10,000 square feet of lawn depending upon which size of bag you purchase. Bonus S Southern Weed and Feed kills dollarweed, dandelion, oxalis, chickweed, purslane and several other common weeds. Use it on St. Augustine, floratam St. Augustine, carpetgrass, centipede and zoysia lawns. Apply in spring or any time weeds are actively growing in the lawn, and water the lawn thoroughly so the product will penetrate the grass. On warm days with temperatures above 80 degrees Fahrenheit, water immediately after applying weed and feed. Bonus S Southern Weed and Feed has a fertilizer analysis of 29-1-10.

Scotts Turf Builder Weed and Feed 3 helps thicken lawns and controls weeds common in lawns in more northerly climates like crabgrass, creeping charlie and oxalis. It is good for lawns with Kentucky bluegrass, fescue, rye grass, centipede, bahia grass, Bermuda or zoysia.

Rain after weed and feed is applied will wash away the weed control particles.
