Nutsedge produces many nut-like tubers and rhizomes, which, in turn, produce new plants. Unlike other lawn weeds, this weed is a member of the sedge family and requires the use of specific herbicides for satisfactory control. Two professional products are available for use. Add a spreader-sticker for improved efficacy. A repeat application may be needed 10 to 14 days later.
Total kill occurs in three to five weeks.
Dandelions were in full bloom in southern Ohio by the second week of April. Most homeowners are usually anxious to apply herbicides to dandelions when they see them. However, for effective control, applications of postemergence chemicals should wait until dandelions reach the early puffball stage. These herbicides also provide good control of chickweed. It propagates from underground rootstocks and will sprout from any root pieces left after weeding.
