I live in south Louisiana and have nut sedge actively growing. It was 84 degrees today (Oct 27th).
Temperatures can have an effect on the SedgeHammer Herbicide. As long as the nutsedge is still actively growing it can be applied. Colder temperatures can prohibit growth of weeds, but you should still get usage out of the product with those temperatures.
