What Is Milorganite and Is It Worth Using?
Milorganite is an organic fertilizer (6-4-0) made from heat-dried microbes at the Milwaukee Metropolitan Sewerage District since 1926. It's excellent for lawns and gardens because it cannot burn, releases nutrients slowly over 8-10 weeks, contains 2.5% iron for natural greening, and is safe for pets and children immediately after application. The trade-off is lower NPK requiring higher application rates (32 lbs per 2,500 sq ft).
