We've had a warm winter in Pennsylvania and the sedge has popped up in mid-February and is actively growing. It's been in the 40s and 50s, but the night temperatures are around freezing many nights. Can I apply it now or is that a waste? Should I wait until at least it isn't freezing at night?
Temperatures can have an effect on the SedgeHammer Herbicide. As long as the nutsedge is actively growing it can be applied, however, the colder temperatures can prohibit growth of weeds as well, but you should still get some use out of the product as long as it is applied while soil (not air) temperatures are a minimum of 65 degrees or higher consistently for a week or more. Please be sure to review the product label for more information and complete application instructions.
