Description:

Kudzu is a type of flowering plant that is commonly found in fields and other grassy areas. It is a member of the Fabaceae family which also includes plants such as beans and peas. Kudzu is an annual or perennial plant that produces small purple or white flowers and clusters of seeds. The plant is often used as a cover crop to improve soil health and suppress weeds. It is also known for its ability to grow quickly and cover large areas of land. In some areas kudzu is considered a weed because of its ability to invade cultivated areas and cause allergies and other health problems.

Q: What does kudzu destroy?
A: This plant, native to Japan, stretches and expands across pastures, fields and gardens, its vines smothering and choking everything in their path including native species, wild spaces and even structures. Kudzu can grow 12 feet a day, eventually reaching more than 100 feet.

Q: Why kudzu is a problem?
A: Kudzu is extremely bad for the ecosystems that it invades because it smothers other plants and trees under a blanket of leaves, hogging all the sunlight and keeping other species in its shade.

Q: What naturally kills kudzu?
A: If the kudzu is growing in an area that can be mowed, persistent mowing from May to October each year will eventually kill the kudzu. Follow up mechanical treatment with herbicide by spraying the foliage of re-sprouts, or cutting the tops of the root crown and painting herbicide directly on to the cut surface.

Q: What eats kudzu in Japan?
A: The plant has no native predators, as it does in Japan and China, where it originated. Mother Nature is no help either.
Source

Q: Can kudzu be stopped?
A: To stop new kudzu vine growth, cut just below the root crown and remove the root crown from the soil. Kudzu cannot regrow from below the root crown, and it does not sprout from lateral roots. Sometimes vines may be buried under a few inches of organic matter and leaf litter.

Q: What was kudzu originally used for?
A: The first recorded use of kudzu in North America was as a shade plant on porches in the American South (the plant produces attractive, fragrant purplish flowers in mid-summer).

Q: What states are affected by kudzu?
A: Today, kudzu is estimated to cover 3,000,000 hectares (7,400,000 acres) of land in the southeastern United States, mostly in Alabama, Georgia, Tennessee, Florida, North Carolina, South Carolina and Mississippi.

Q: Is kudzu good for animals?
A: Kudzu is palatable, and has given first-rate results as a pasture for beef and dairy cattle; and results showed no difference in the color or flavor of milk produced from cows consuming it [9] . Kudzu can be grazed, cut for cut-and-carry feeding systems or mixed with grass to make good quality silage.

Q: Is kudzu a problem in the US?
A: While no longer on the Federal Noxious Weed list, kudzu is currently listed as a noxious weed in 13 states. It is estimated that kudzu may cover more than one- quarter million acres in Alabama. Kudzu has spread north into Pennsylvania and Illinois and west into Texas, Oklahoma, Iowa, and Nebraska.

Q: What state has the most kudzu?
A: Kudzu covers an estimated 7.4 million acres of land in the Southeast, with the heaviest infestations in Georgia, Alabama and Mississippi.

Q: Does kudzu have a purpose?
A: Kudzu is a botanical used in traditional medicine to treat alcoholism, cardiovascular disease, menopausal symptoms, diabetes, fever, the common cold, and neck or eye pain. There are several species of kudzu and both the flowers and root extract are used for their medicinal properties.
Source

Q: Why is kudzu so successful?
A: Because of its underground root crowns, kudzu can escape fire damage. During the growing season, kudzu’s underground root system can provide significant water to the foliage; the high water content stems and foliage are able to resist some fire damage that may kill nearby native plants.

Q: What animal eats kudzu?
A: According to Purdue University, continuous mowing and grazing – both cattle & goats will eat kudzu – will weaken and eventually control the plant. For larger growths, the vines should be cut near the ground and then carefully treated with one of a variety of herbicides.
Source

Q: What kills kudzu permanently?
A: RM43, your go-to for most weed control, can also kill kudzu. It is a combination of 43 percent glyphosate herbicide and a surfactant. Use it as an alternative to BRUSHTOX but only on non-crop areas as RM43 kills both weeds and grasses.

Q: Do snakes live in kudzu?
A: Snakes are one of the most common things underfoot.

Q: How does kudzu work for alcoholism?
A: Daidzin, a compound found in the kudzu vine, interferes with the metabolization of alcohol and produces effects similar to those of the anti-drinking drug Antabuse.
