What is post-emergent herbicide? Do I need to apply a post-emergent herbicide to my lawn?? While most people have heard about pre-emergents, many overlook the importance of post-emergent herbicide on your turf to make it looks its best.
Post-emergents attack weeds after they have shown their ugly little heads. The “post” part of this type of herbicide refers to the fact that it is used on already existing weeds. Post-emergent weed killers either attack the foliage or flow systemically to the roots of the weed. They come in spray on formulas or as granular applications. They are most useful in areas that have literally been taken over by weeds, but you must use caution when applying to prevent drift of the spray or contact with non-target plants.
