Scotts® MAX™Weed & FeedI is an innovative combination product that kills existing weeds, including dandelion, dollarweed, clover, knotweed, purslane, bindweed, and more (as listed). In addition, it feeds grass and strengthens the lawn. Essential nutrients include kelp meal, worm castings, iron, and manganese. Scotts® MAX™Weed & FeedI is for use on on Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass lawns. Apply when lawn is wet with dew or after watering, as the moisture helps the particles adhere to weed leaves to produce best results. Use when grass and weeds are actively growing and daytime temperatures are consistently between 60° and 90°F. We recommend using a Scotts® spreader to apply this product. For Scotts® broadcast/rotary spreader, use a setting of 3 1/2. For Scotts® drop spreader, use a setting of 7 1/4. For Scotts® Wizz® spreader, use a setting of 4 1/4. Wait at least 24 hours before watering your lawn, as water will wash the product off the weed leaves and reduce the effectiveness of the product. Mow tall grass a day or two before application. One 39.50 lb. bag of Scotts® MAX™ Weed & FeedI covers 14,000 sq. ft.
