We use Milorganite on our lawn and gardens. Works great!
My secret recipe for southern lawns (saint Augustine grass)
50# of miloganite
25# of magnesium sulfate
50# of weed and feed
Mix in wheel barrow and spread on lawn
Grass will be so green it looks blue
Fertilize in September and January
I went out to pick up some Milorganite. Took a close look at the bag and found some disturbing information. First: On the bottom of the bag “Manufactured by: Milwaukee Metropolitan Sewage District, 260 W. Seeboth St., Milwaukee, WI 53204.” Next: In the area where it says 6-4-0 Guaranteed Analysis “Derived from Biosolids, 4.0% Nitrogen Derived from Biosolids.” I’m pretty sure, based on the manufacturer, that biosolids are...well...turds. Lastly: In the big paragraph on the back that starts with Growing Beautiful Lawns, Trees, Shrubs and Flowers since 1926 “WARNING: This product can expose you to chemicals, including lead, known to the State of California to cause cancer and birth defects or other reproductive harm.” Kind of scary. I did not buy it.
