The purple nutsedge is the most “common” member of the Nutsedge family in the Southeast. Yellow Nutsedge and Green Kyllinga are two other Nutsedges found in the South, though not as frequently. Nutsedge is a very difficult weed to control. Nutsedge grows taller than your turf and can be identified by the shiny leaf coating. This is a perennial, grassy weed that spreads aggressively through its seeds, rhizomes (under-creeping stems), or nuts (tubers). The underground “nuts” can lie dormant for several years, requiring an active vigil over previously treated areas.
Sedges are immune to premergence barriers and tend to proliferate during periods of excess rain. Small “invasions” of purple nutsedge and yellow nutsedge can be effectively combatted by digging out the offending Nutsedge. There is also a product available that can suppress Nutsedge in situations with large populations. This product, applied in late spring or early summer, will selectively control the Nutsedge after it has emerged from dormancy. In bad infestations, a follow-up treatment may be needed later in summer for controlling potential regrowth. Even with treatment, nutsedge is likely to return.
As you can tell, this product works to suppress purple and yellow nutsedge activity during the growing seasons and is not a one-time, complete-kill product. If you wish to schedule this extra weed control treatment, please call our office.
