Why Use Milorganite?
Proven for 90 years
Golf course professionals and homeowners have trusted Milorganite’s consistent, long-lasting results for nine decades. Now that’s proven!
Truly All Purpose
Milorganite is an all-purpose slow-release nitrogen fertilizer that can be used safely on lawns, flowers, vegetables, shrubs and trees, as well as a carrier when spreading grass seed.
Doesn’t Burn Plants
You don’t have to worry about streaks, stripes or accidentally burning your lawn when you use Milorganite! It contains virtually no salts, so it won’t burn plants, even in the hottest temperatures or driest conditions. You don’t have to water it in. It’ll stay in the soil ready to work when moisture becomes available.
Iron for Greening without Staining
Grass needs iron for the long-lasting, deep, vibrant green lawn you want. Milorganite delivers organically complex iron throughout the feeding period and won’t stain concrete, unlike iron salts in some synthetic fertilizers.
Slow-Release: Steady Growth, Less Runoff, Fertilize Less Often
Milorganite’s slow-release formula provides nitrogen and other nutrients for up to 10 weeks after application. This provides even growth and better root development over a longer period of time, instead of a sudden growth spurt and excessive grass clippings. Remember: the best defense against weeds is a healthy lawn!
Slow release is also good for the environment; Milorganite’s nutrients release at a rate that plants can use making it less likely to leach into groundwater.
Slow release is good for gardens, too. The slow release organic-nitrogen feeds plants evenly and gradually. It doesn’t interfere with flowering or fruit development. Milorganite also encourages root development, which results in abundant yields.
Adds Organic Matter to Feed the Soil
Healthy soil is the key to healthier grass and plants. Milorganite is composed of 85% organic matter, which nourishes the plant and feeds the soil microbes. This improves the soil’s ability to grow grass and other plants. Milorganite is ideal for sandy soils, because it adds organic matter and doesn’t leach, which means the water-soluble nutrients aren’t washed away.
Environmentally Friendly, Sustainable
Milorganite has been recycling since 1926, to make a nutrient-rich byproduct that is transformed into a highly effective fertilizer. There are no mined resources or synthetics in Milorganite. Production of Milorganite is guided by our dedication to be good stewards of the environment.
Safety is our number one concern. Milorganite meets stringent criteria imposed on any fertilizer product for health, safety, and environmental concerns. Milorganite complies with all federal and state regulations, which allows Milorganite to be used for all of your fertilizing needs when used as directed.
