Vigoro Ready-To-Spray Lawn Fertilizer 20-0-0 is the fast, easy way to fertilize your lawn. There's no complicated mixing - just connect to your hose and spray. Formulated with 20 percent nitrogen to green up the lawn in 24 hours. Apply Vigoro Ready-To-Spray Lawn Fertilizer 20-0-0 to actively growing turf. Determine the size of the area to be treated, being sure to subtract all non-lawn areas from your calculation. Shake the container well before using, then connect the garden hose to the sprayer nozzle as directed. Extend hose to the furthest area to be treated and work back toward the faucet. This product feeds up to 3,500 square feet of lawn (except for Florida lawns). When using on Florida lawns, check the product label for application guidelines. Simply connect a garden hose to the hose-end sprayer nozzle and go-no manual mixing is required. Apply once every two weeks (check the label for Florida applications). For best results, fertilize your lawn when grass is actively growing and storing nutrients - for most places, this is in the spring or early fall.
