Controlling Nutsedge in Your Lawn

Nutsedge is a warm-season, perennial grassy weed found on many home lawns across the U.S. Its three-leaf structure, light green color, and rapid growth rate create a non-uniform lawn, making it distinguishable from desirable grasses  Although there are many different types of nutsedges, yellow and purple are the most common varieties of these turf pests.
The leaves on nutsedge are thicker and stiffer than most grasses and are arranged in sets of three at the base. Yellow nutsedge has light brown flowers and seeds, while purple nutsedge flowers feature a reddish tinge with dark brown or black seeds.  
Control Tips
  • Remove small plants by hand every 2-3 weeks during the summer, as this will weaken the plant by depleting its energy reserves.
  • Do not overwater. Excess moisture will cause nutsedge to thrive in your yard. 
  • Prune shrubbery and surrounding trees to provide your lawn with optimal sunlight. 
  • Fertilize regularly to encourage healthy turf.  
Nutsedge will spread rapidly on your lawn if there is no competition from healthy turf to crowd it out.  It will also impact your vegetable, plant, and flower beds throughout the growing season if not kept in check. Because nutsedge becomes more difficult to control once it is present on established turf, preventative measures play a critical role in management. Maintaining a thick, healthy lawn is the best defense for keeping out unwanted weeds.  
In cases where large infestations are present, an application of a control product may be necessary. Your Weed Man professional can help you find the best solution for keeping your lawn healthy, dense, and weed-free for years to come.
