I dug up an entire nutsedge and thought I'd post a photo. I don't get a lot of the nuts when I remove them. You can't just pull it out, that nut breaks right off. That's a fairly large nut, I've seen several much smaller. Sometimes that nut is an inch or so underground, not as deep as this one was.
This one looks like it had been broken off before. That nut just keeps sending up new shoots it seems like forever. That nut does not run out of energy very fast.
I pretty much got it at the right time, before it reproduced. Eventually it would go to seed but the way I hate is that when they get about this much growth above-ground they start sending out Rhizomes which become new plants. Also they form nutlets underground that will become a new plant. They start reproducing really young, if you don't stay on top of it they can quickly become a thick mat. Nutsedge loves a wet poorly drained soil, like the swamp muck that makes up a lot of my soil.
