Milorganite fertilizer works by slowly releasing organic-nitrogen into your lawn as it grows. Each application feeds for up to 10 weeks. Milorganite also contains iron that enhances the color of your lawn throughout the feeding period. The salt-free formula won't burn your lawn, so you'll never have to worry about streaking or burn spots.

Healthy soil is the key to a great lawn. Milorganite is composed of 84% organice material, which promotes healthy soil and, in turn, improves the soil's ability to grow plants.

Milorganite runs more tests than any other fertilizer manufacturers because we want to deliver a product that is safe for you, your children, and your pets.
