Milorganite® is an All-Purpose Fertilizer
What does Milorganite do? 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.
Milorganite® Will NOT Burn Your Lawn or 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 your lawn, trees, shrubs, or 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.
Milorganite® Helps Green Your Lawn
Milorganite's iron greens 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. Read our blog, What Color Should My Grass Be? to learn about what shade of green your lawn should be, what makes grass green, and tips for a greener lawn.
Milorganite® is a Slow-Release Fertilizer
Milorganite’s slow-release formula provides nitrogen and other nutrients for up to 8-10 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 are released 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 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.
Milorganite® 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.
Milorganite® is Environmentally Friendly
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. The production of Milorganite is guided by our dedication to being a good steward of the environment.
Milorganite® is Safe
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.
