Treat weeds and feed your lawn with Scotts Turf Builder WinterGuard Fall Weed & Feed 3 in the fall for a better lawn next spring. This weed killer plus lawn fertilizer controls over 50 listed lawn weeds, including clover, dandelion, plantain, morningglory, chicory, eveningprimrose, and purslane. In addition, it delivers the nutrients needed to help recover from damage from the summertime and build strong roots to take on harsh winter conditions. Apply on a calm day when weeds are actively growing and temperatures are consistently between 60 Deg. F and 90 Deg. F. Make sure your grass is moist from dew or sprinkling, as this helps particles adhere to weed leaves to produce the best results. We recommend using a Scotts spreader to apply this product. For Scotts broadcast/rotary spreaders, use a setting of 3 . For Scotts drop spreaders, use a setting of 6. Do not water your lawn for 24 hours after application. This lawn care product is for use on Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass. Do not apply to St. Augustinegrass (including Floratam), Dichondra, Lippia, Carpetgrass, or Bentgrass.
