Controlling Nutsedge in St. Louis

The lawn care season is moving right along into the summer and as the weather continues to get warmer, the risk of warm-season weeds such as nutsedge increases.  Nutsedge is a perennial weed that grows across the entire U.S. and is generally light green in color with a rapid growth rate that makes lawns appear uneven.  There are many varieties of nutsedge with the purple and yellow types being the most common found in the St. Louis area.

Nutsedge is a very difficult weed to control once it establishes itself in a lawn which is why early identification is important.  Its leaves are thicker and stiffer than that of grass and they grow in sets of three at the base of the plant.  The flowers and seeds of yellow nutsedge are light brown and the flowers of purple nutsedge are reddish in color with black or dark brown seeds.  If you notice light nutsedge growth in your lawn, there are some actions you can take to help keep them under control.

Control Tips

  • Pull small nutsedge plants by hand every 2 to 3 weeks in the summer to deplete its energy sources.
  • Employ light watering techniques; nutsedge thrives in lawns with excess moisture.
  • Prune shrubs and trees to allow more sunlight to reach the lawn.
  • Fertilize regularly to promote a strong root system.

Once nutsedge appears in your lawn, it can spread quickly if the turf is not strong enough to compete for nutrients.  Nutsedge can also cause problems for vegetable, plant, and flower beds if it is not effectively controlled.  The best way to prevent nutsedge is by maintaining a thick, healthy lawn with proper watering and fertilization, but even the best maintained lawns can still exhibit weed growth.
