      Answer This Question

      Stop pretending this crap is “organic.” Milorganite is sewage sludge — toilets, hospital waste, PFAS, pharma residue, industrial runoff — bagged and sold as fertilizer. EPA whistleblowers walked out over this corruption. I’m not spreading processed sewe

        What about the PFAs in this product, is it true and are they risky?

        Answer This Question

        It legally contains PFAS “forever chemicals,” pharmaceuticals, heavy metals, and other toxins that don’t break down and contaminate soil and groundwater. It’s legal only because the EPA reclassified it as “fertilizer” to avoid hazardous waste laws. Sneaky

                Miloganite is a great product. Completely organic, will not burn your lawn. Use it in July and August when the weather is extremely warm without fear. Its a slow release fertilizer.

                  Milorganite truly does progressively strengthen your lawn's roots and make for lawn thicker and darker. I apply it every spring.

                  Good results but problems with product consistency
                  I have been using this fertilizer for about a year now and I am impressed with its results. However, the last bag I purchased had significant issues with the quality of its consistency. There were lots of chunks that interrupted the operation of my spreader, causing it to apply inconsistently. Shown in the picture is a sample of the chunks I picked out of just a 10 lb pour. Maybe just a bad batch. Hopefully the QC folks can look into this.

                      Bad Milorganite
                      Do NOT Buy this Product from Home Depot ( as I routinely used this brand for lawns ) now they sell with rocks inside to add weight! Unbelievable!
