Effective Ways to Control Quackgrass

Quackgrass is known to be a weed that causes problem in gardens and lawns. It is native to Europe but has been growing in the United States for over two hundred years in all the states except Arizona, Florida and Hawaii. In the past, quackgrass are referred to as quitch, wheat, scutch, devils, witch, twitch or durfa grass. It is listed in forty-one states as a poisonous weed due to its harmful effects on different agricultural crops. However, quackgrass is helpful in controlling soil erosion.

Quackgrass can attack lawns that have vegetables or perennial flowers, which makes it very difficult to get rid of. It is necessary to know the growth process of quackgrass in order to avoid committing common mistakes in destroying this plant. Underground, quackgrass grows from one to four feet in height from rhizomes with flat, thin and bright green leaves. The quackgrass seed appears in July and grows from three to eight inches long. Usually, it is found in rye straw, so it is best to avoid using this in your home garden. Each plant produces around twenty-five seeds that can last for three to five years. It is necessary to destroy the plants before developing rhizomes.

Rhizomes or underground stems are 1/8 inch in diameter, yellow to white in color and has distinct nodes or joints. Each joint has the ability to produce roots and send a new grass blade in the soil; the rhizomes are tough and can grow through a potato or push through the asphalt pavement. If left unfettered, these rhizomes can form a solid pad that is four inches thick in the surface of the soil. One quackgrass can generate three hundred feet of rhizomes every year. Remember not to use a rototiller in areas where quackgrass grows because this may propagate thousands of new plants.

The best way to get rid of quackgrass is to use herbicide that has glyphosate. 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. Use a non-selective herbicide that 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.

You can also apply nitrogen fertilizer in order to solve lateral bud dormancy. 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. The application of herbicide must be repeated every thirty to forty days and it is necessary to avoid cultivation for two weeks after every herbicide application.

In flowering beds or vegetable gardens, there are other effective methods in getting rid of quackgrass. Numerous spring cultivations must kill and sprout any weed seeds before developing rhizomes. As much as possible, use mulch in order to smother plants. It is necessary to dig the rhizomes by hand to avoid breaking them in the soil and they must be dried and disposed. It is best to eliminate the plant blades repeatedly using a hoe.

Quackgrass is very difficult to destroy and it is necessary to know the right methods in order to eliminate them effectively and safely.
