Lawns across the country are infested with a troublesome weed grass called quackgrass, sometimes referred to as couch or twitch grass.
Quackgrass is faster growing and lighter green in color than desirable lawn grasses such as Kentucky Bluegrass.
Weak lawns are ideal sites for the invasion of unsightly quackgrass.
Infrequent grass cutting and poor watering habits encourage Quackgrass invasion.
Quackgrass also thrives in undernourished, weak lawns and will quickly spread throughout the lawn.
Quackgrass reproduces most often by vigorous underground stems called rhizomes.
Few people are aware of quackgrass invasion until desirable grasses such as Kentucky Bluegrass are crowded out.
Quackgrass gives the lawn a coarse uneven appearance.
There are no selective weed control materials for quackgrass. The most effective procedure for control and/or suppression of quackgrass is to "stunt it out" or "crowd it out". This is accomplished by:
applying a good fertilizer program, such as Weed Man slow release granular fertilizer, to the lawn in order to thicken desirable lawn grasses.
in addition, the lawn must be cut frequently (every 3-4 days) at a slightly lower height than is normally recommended, approximately 1 ½ to 2” (4-5 cm).
These procedures have the effect of stunting the taller growing quackgrass. Desirable grasses will then begin to crowd the stressed quackgrass and will ultimately result in a vigorously growing, healthy green lawn.
Patience and diligence are essential ingredients in this procedure. It may take 2-3 years to control quackgrass naturally. Ask your Weed Man for tips on watering.
