Quackgrass is a cool season, perennial grassy weed. Quackgrass breaks dormancy at the same time as our normal turf does in the spring. Quackgrass is often mistaken as Crabgrass but remember if you see this grassy weed in the spring or early summer it is definitely Quackgrass. Quackgrass is very hard to control oreradicate for several reasons. As with any weed your best offense is to have a healthy, dense turf. 

Quackgrass spreads through Rhizomes or underground stems one to four feet in height within the soil. Each joint has the ability to produce roots and send a new grass blade to the surface of soil. Remember not to use a rototiller in areas where quackgrass grows because this may propagate many new plants from the rhizomes.
To control/eradicate quackgrass you will need to stimulate lateral bud dormancy by applying an application on nitrogen. Nitrogen fertilizer tends to break lateral bud dormancy and helps in trans-location of herbicide to the plant tissue in order to destroy the entire plant. An application of a non-selective herbicide that contains glyphosate most commonly know as, “Round up” is needed to kill the plant. This must be used when there is no wind and no rain for twenty-four hours. For best results, the plant should be green and growing actively. Be careful because use of a non-selective herbicide can destroy almost any kind of green plant as well as woody plants. Make sure to apply this only to the areas you want to get rid of quackgrass. After a week to ten days the plant should be dead. Dig up the dead areas and remove completely. Do not rototill!  Replace with good, sterile black dirt and either reseed or resod. Another application of herbicide might be repeated every thirty to forty days if necessary. 
Quackgrass is a tough grassy weed to eliminate, but by using the proper methods it can be eradicated successfully.
