The nutrients cannot be washed away by rain, unlike most liquids applications.

The granules cannot be mowed away because they fall immediately to the soil surface rather then sticking to the grass blades.

Granules release the nitrogen slowly, allowing your lawn to grow thicker and greener.

Liquids, on the other hand, deliver quick blasts that make your lawn grow faster and longer, keeping you behind the lawnmower.
