## Overview

Milorganite All Purpose Eco Friendly Slow Release Nitrogen Fertilizer (6-4-0) is a 5-pound pack of 4 bags designed to feed up to 2,500 sq. ft. of lawn and garden space. Its unique slow-release formula provides nitrogen and essential micronutrients for 8-10 weeks without burning plants, thanks to virtually no salts. The iron-rich content promotes vibrant green growth without staining surfaces. Made sustainably from heat-dried microbes sourced from wastewater, Milorganite supports strong roots and healthy plants across lawns, shrubs, flowers, trees, and vegetable gardens.

## Description

Each bag delivers primary nutrients Nitrogen and Phosphorus to plants as well as important micro-nutrients that they need to develop. Milorganite is made from microbes that eat the organic material found in wastewater, die when they have nothing else to eat, and are heat-dried in dryers that operate at 900-1200 degrees Fahrenheit. There’s no immediate, excessive release of nutrients after fertilizing, which causes a flush of growth. This slow-release formula results in uniform growth and a well-established root system. Milorganite has no expiration date. It will work indefinitely if stored properly in a cool and dry area out of the reach of children and animals.
