My dads buddy who does lawn care also, we were talking to him bout fert and he says if you put down worm crap which you can buy from fert places it will green up a yard real quick but there will be alot of flies anybody done this?
I've seen it for sale under the brand name Worm Gold but it's too bloody dear to be broadcasting on a lawn. It was about $1/ pound. They were creating a liquid from worm castings called Soil Soup or some such name that had some very impressive scientific reviews. It was also expensive but showed results VERY quickly. A professor in San Diego actually used it to REVERSE Sudden Oak Death Syndrome in Central California.
