What is that light green grass that seems to grow quickly
You may be looking at nutsedge.
Have you noticed a kelly green, light bladed plant that pops up a day or two after the lawn has been mowed?
Nutsedge (commonly called “water grass”) is an annoying problem. Botanically it is a sedge, not a grass. Nutsedge is difficult to eliminate because it spreads in three different ways: by its seeds, by its rhizomes (roots that run laterally,) and by “nutlets” —tiny onion like nodules that grow at the end of the rhizome and sit dormant in your lawn (which is why Nutsedge may reappear after you pull it.) Nutsedge, like most weeds, grows fast.
How can you prevent and control Nutsedge?
The best defense is a lush lawn. A grass canopy blocks sunlight and keeps soil cool, frustrating the Nutsedge. Monsanto has developed a product called “Manage” for Nutsedge control. Manage is designed to control Nutsedge without stressing or damaging turf. A second application may be required 6–10 weeks later, however; no more than two applications per year are recommended by the label.
