Sedgehammer is meant more for nutsedge control in turf grass and it cannot be used near a vegetable garden or anything edible. For nutsedge in landscaped areas it is recommended to spot treat the sedge with a glyphosate or Round Up type product directly. We recommend Roundup QuickPro 1.5 oz. packs for ease of use
No, you do not have to pull the weeds after applying SedgeHammer Herbicide, however, continually removing shoots eventually depletes the energy source reserves in the tubers. Tubers are key to nutsedge survival. If you can limit production of tubers, you’ll eventually control the nutsedge itself.
Sedgehammer Herbicide is applied to the foliage of the nutsedge or other labeled weeds you are targeting.

You could also spot treat with a glyphosate based product like GlyPhoSel Pro and then reseed/so the area. The University of Florida has some information here about.
