Milorganite Eco-Friendly 6-4-0 Fertilizer for Lawns, Flowers, and Gardens

From the Brand

Over 95 Years of Recycling

Milorganite fertilizer represents one of the nation’s oldest recycling initiatives. Since 1926, Milwaukee has been converting nutrient-rich microbes from its water reclamation process into Milorganite's slow-release nitrogen fertilizer. These recycled nutrients are safely applicable to lawns, flowers, vegetables, shrubs, and trees.

Natural Commitment to the Environment

Milorganite and MMSD (Milwaukee Metropolitan Sewerage District) are dedicated to sustainability. We constantly strive to cut down on energy use, waste, and emissions. Our commitment extends through our products, services, operations, and community activities, focusing on efficient resource use to benefit both people and the planet.

A Sustainable Vision

MMSD leads nationally in green solutions to safeguard our freshwater sources. By 2035, MMSD aims to source 80% of its energy from renewable sources. To support this goal, Milorganite is already utilizing alternative energy sources like solar power, landfill gas, and digester methane in its production processes.

Product Description

Does Milorganite have an odor?

Milorganite has an earthy smell upon application, which should dissipate within a few days. Rain or watering can help reduce the odor.

How to store Milorganite?

Store Milorganite, like all fertilizers, in a cool, dry place away from children and pets. If kept in a dry shed or garage, seasonal temperature changes will not impact the product’s quality or effectiveness.

What is a biosolid?

Biosolids are residual microbes that have processed nutrients from sewage waste streams.

Does Milorganite expire?

Milorganite does not have an expiration date and remains effective indefinitely when stored properly in a cool, dry location. Seasonal temperature variations in a dry shed or garage will not affect its quality.

Can I apply Milorganite on top of mulch?

Yes, you can apply Milorganite on top of mulch, although it will take longer to integrate into the soil. Alternatively, you can rake back the mulch, apply Milorganite, work it into the soil, and then replace the mulch.

When can my dog return to the lawn after applying Milorganite?

Some dogs might be attracted to Milorganite’s odor, which could lead to them rolling on or eating the freshly fertilized areas. To minimize this, water the lawn after application.

What should I do if my dog ate Milorganite?

If your dog consumes Milorganite, there’s no need for panic. It’s not life-threatening or an emergency. However, your dog might experience some discomfort.

Is Milorganite safe?

Milorganite meets federal and state standards for public health and environmental protection. It can be used safely for fertilizing lawns, trees, shrubs, flowers, and vegetables.

Is Milorganite effective in clay soil?

Milorganite works well in clay soils due to its 85% organic matter content. Organic matter enhances soil drainage, aeration, temperature regulation, and provides pore space, all essential for optimal plant growth.

Is Milorganite effective in sandy soil?

Milorganite is beneficial for sandy soils as well, adding organic matter that improves soil structure. Its water-soluble nutrients release slowly, reducing leaching and promoting healthy microbial activity for robust soil health.

Does Milorganite cause streaks or burn the lawn?

Milorganite contains minimal salts, so it will not burn your lawn, trees, shrubs, or plants, even under extreme conditions. It also delivers iron without staining, providing a deep, vibrant green lawn without the risk of concrete staining.

How long does Milorganite last?

Milorganite’s slow-release formula supplies nitrogen and other nutrients for up to 8-10 weeks after application and doesn’t require watering in. It covers 2,500 sq. ft. and supports strong root development and sturdy stems in lawns, flowers, shrubs, trees, and gardens, ensuring a bountiful growth.
