Milorganite is the ideal choice for “Organic Option” programs frequently offered by professional lawn care and landscape operators, providing the best value of any organic-based fertilizer on the market. It won’t burn turf and is so versatile that it can be used wherever customers need fertilizer. Produced and sold since 1926, Milorganite delivers the results customers demand.

Cool-Season (Northern) Grasses

Cool-Season Grasses such as Kentucky bluegrass, Fescue, and Perennial Ryegrass should be fertilized four (4) times per year.

In spring, fertilize your lawn with Milorganite after the last frost and once your lawn begins to grow and green. A good rule of thumb is when daytime temperatures are consistently in the 60s, which means soil temperatures are in the mid-50s. Check out this online tool to learn your current soil temperature. If you fertilize too early, the plant will focus on shoot growth, and you will sacrifice root growth. Deep roots help your lawn better withstand drought conditions during summer months.

For the last application, fertilize with Milorganite as late in the season as possible—just before the first deep freeze or snowfall. This fertilizer application, known as “dormant feeding,” encourages a healthier, greener lawn in spring.

Warm-Season (Southern) Grasses

Warm-Season Grasses, such as Bermuda, St. Augustine, Centipedegrass, Bahia, and Zoysia, should be fertilized four (4) times per year. Centipedegrass and Bahia grass prefer spring and summer feedings, and to help prevent winterkill, avoid fertilizing these varieties in the fall.

In spring, fertilize your lawn with Milorganite after the last frost and once your lawn begins to grow and green. A good rule of thumb is when daytime temperatures are consistently in the 70s, which means soil temperatures are in the 60s. Check out this tool to learn your current soil temperature. If you fertilize too early, the plant will focus on shoot growth, and you will sacrifice root growth. Deep roots help your lawn better withstand drought conditions during summer months.

Avoid fertilizing southern grasses too late in the fall. The grass is trying to go dormant and when you fertilize you’re encouraging it to grow. This may cause your lawn to be less hardy as it enters cold weather and more susceptible to winter injury. The last time to fertilize warm-season grasses in fall is one month before dormancy or the average first killing frost.
