You don't say what type of nutsedge you're trying to control.

*I'm* not trying to control anything. Please learn how to
quote/reply/attribute/post.

If it's yellow
nutsedge, controlling it is about all that can be done until it runs out of
energy and stops sending up shoots.

Horsehockey. Sedgehammer will knock it right out. A treatment again, before
the plant goes dormant, will take the dose of herbicide right down to the
tuber, effectively killing it (if the first app doesn't do it, though under
proper conditions it should).

Purple nutsedge, on the other hand,
might have some method of killing it, from what I've seen in some obscure
article on the internet;

Ahh! So you get your information on the internet. We /all/ know that it
*must* be true, then! Especially if it's an obscure article. The more
obscure, the more truth, yup!

but don't hold your breath. Spray the shoots with
anything that will kill the shoots,

Sure, spray "anything" that will kill the shoots. Hell, glyphosate will
kill the shoots. It'll also kill any plant in the local area, that it
touches. Much better advice would be to spray a product with
methanearsonate in it.

but don't expect to kill the seed-nut
because it will continue sending out shoots until it depletes its energy
source.

No, if you're just spraying anything, willy-nilly, you probably won't get
the tuber. BTW, it's a tuber, not a "nut".

Of course, you can alway try to dig it out, but it no guarantee that
you'll find the nut. Just keep spraying, and pull out the occasional lone
shoot. The nuts are edible, in case you wish to gather a fistful and clean
them and roast them. Just about the time you begin to enjoy them, they'll
probably die off!

The first full-truth you've made. The tuber is edible.

By the way, nutsedges are allelopathic (like walnut trees) and secrete a
chemical that discourages growth of other plants in order to assure its own
survival.

More internet wisdom? Cyperus esculentus and C. rotundus are known for
their allelopathic abilities against (please try and keep up, here)
*CERTAIN* plants (most notably corn and cotton). This does *not* apply to
turf grass. Unless their yard is full of corn or cotton, I doubt they'd
have to worry.

Definitely a good idea to get rid of it if you can.

Again, *I'm* not the one with the nutsedge problem. But, were I, that would
be good advice.
