I've been following your "Organic lawn care for the cheap and lazy" advise for over 10 years and have been using organic fertilzers on my lawn for as long. I've used Ringer and a Ringer clone "Purely Organic" and for the last 2 years "Dr. Earth". The "lawn care nuts" on youtube are always promoting the use of a fertilizer called Milorganite. It is a biosolid that is a waste product of the Milwalkie sewer system that is supposed to be organic. What is your opinion of this fertilizer? Is it something that would be ok and good to use or is it something to stay away from?
