Some weed and feed feature slow-release formulas so you don’t have to fertilize as often. Granular versions offer a better value for your money, but you do need to water your lawn after application for it to penetrate the grass. Granular weed and feed covers more area, often 5,000 square feet or more, and are available in 18-lb bags and larger. Spray or liquid weed and feed are designed for small yards.
