The grass is greener with the help of Scotts® Green Max™ lawn food. This fertilizer plus iron supplement feeds your lawn and provides deep greening in just three days. The product contains 5 percent iron, a micronutrient that enhances the greening process for fast results, and features the exclusive Scotts® All-in-One Particles® technology to blend the ideal ratio of nutrients into each individual particle. Plus, it is guaranteed not to stain concrete, driveways, or other surfaces surrounding your lawn (when used as directed). Scotts® Green Max™ lawn food can be applied to any grass type in the spring, summer, or fall. We recommend using a Scotts® spreader to apply this product. For a Scotts® broadcast/rotary, use a setting of 3-3/4 for the recommended rate or 3-1/4 for the regular rate. For Scotts® drop spreaders, use a setting of 7-1/2 for the recommended rate or 7 for the regular rate. For fast results, lightly water in.
