I have had success with it before. I'm trying to figure out what caused the nutsedge to take off like it has in the last 3 weeks. Does nutsedge spread by seed? I haven't seen any seed heads on any in my yard. Wondering if my neighbor dropped seed from his mower when he cut my grass.

Seed - I don’t think so, largely the underground tubers. In my yard usually July when it starts emerging. A couple sprays with Sedgehammer 3 or 4 weeks apart controls it for the year. Not sure why your emergence is so late - I’m not seeing any emergence at this time in my yard.

Nutsedge will spread rapidly if it’s raining a lot. Also, a few plants go unnoticed for the most part so all of a sudden it seems like hundreds grew overnight
