Scotts Turf Builder Triple Action1 provides three benefits in one bag. This 3-in-1 formula kills and prevents listed weeds, all while feeding and strengthening your lawn. Ideal for DIY homeowners working outdoors in the yard. It streamlines weed control and prevention and lawn fertilization as a seamless part of your regular lawn maintenance during the spring lawn care season. This clover and dandelion weed killer for lawns plus grass fertilizer not only helps kill listed broadleaf weeds, it also prevents crabgrass for 4 months. It also prevents barnyardgrass, fall panicum, foxtail, and annual bluegrass. Scotts Turf Builder Triple Action1 can be applied to Kentucky Bluegrass, Perennial Ryegrass, Tall Fescue, Fine Fescue, Bermudagrass, Bahiagrass, Centipedegrass, and Zoysiagrass. Apply with a Scotts spreader when dandelions are actively growing. Make sure the grass is wet from dew or watering before applying so the particles adhere to weed leaves. After 24 hours, water the lawn to wash particles into the soil to prevent germination of crabgrass and other listed grassy weeds. Do not allow people and pets to re-enter the treated area until dusts have settled. One 33.94 lb. bag treats 12,000 sq. ft.
