Control broadleaf weeds and fertilize your lawn at the same time with natural, plant-based Weed and Feed Lawn Food from Purely Organic Products. Weed and Feed Lawn Food helps reduce existing weed infestations, and prevent new ones, while also feeding your lawn. For the best results, apply Weed and Feed to established lawns when dandelions, chickweed, and other broadleaf weeds are actively growing. For problem lawns a second application, 4-5-weeks after the first, may be needed. We recommend using a spreader to apply this product (please refer to spreader settings on product label). After application let the lawn stay dry for 2-3-days and then resume watering and mowing as usual. This 15 lbs. bag of Weed and Feed Lawn Food covers 3,000 sq. ft.
