Kudzu has dark-green, hairy, alternate, compound leaves, 2 – 8 inches (5 – 20 cm) in length with three oval- to heart-shaped leaflets 3 – 4 inches (8 – 10 cm) long at the end; these leaves may be slightly or entirely lobed. Warmth and humidity are important factors, with greater colonization corresponding to warmer average annual temperatures and higher average humidity. In the late summer, August or September in the southeastern United States, purple-reddish, spike-liked fragrant flowers appear on the vine. You can use a shovel to expose the base of the root crown and then use an axe to severe the root below the root crown. Up to 30 vines can grow from a single root crown. Above ground, start by cutting the vines at the ground level, then follow up by regularly mowing or hand-cutting any emerging shoots until there is no more new growth. That being said, there have been studies to … Kudzu control costs can be as high as $200 per acre per year. The leaves have tiny hairs and feel fuzzy when you touch them. It can also be dispersed through seeds. Once kudzu gains access to the forest canopy, the liana formed can spread faster and more aggressively through a forest. Cut the vine above and dig around the crown to remove it from the taproots. You likely won't find kudzu root being prescribed by a doctor, but it's actually a staple of alternative medicine. Cut into the crown and apply a solution of 50 percent glyphosate or 50 percent triclopyr and 50 percent water. The vines may directly damage colonized trees by strangulation. You will … Ko-hemp, a more refined version of kudzu fiber has long been used for cloth weaving in China. Applying Herbicides Choose the right herbicide for your needs. Kudzu is an herbaceous to semi-woody, climbing or trailing, nonnative, deciduous, perennial vine or liana (a vine that is rooted in ground-level soil and uses trees and other vertical supports (telephone polls, buildings, etc.) They turn brown as they dry. Kudzu accumulates and maintains substantial carbon reserves in large woody, tuberous roots, again giving it a competitive advantage. Kudzu sends out new growth from the root crown but not the entire root below it. For more details, see our, 9 Species of Fig (Ficus) Trees for Indoor and Outdoor Gardening, Best Vines to Grow on Pergolas and Arbors. Begin by following the vine down to where it enters into the ground. This part is the root crown and is what you will remove. A cold winter will kill young vegetative growth to the root crowns, but the vine resumes growth again in spring. As many as thirty vines may grow from a … It can also smother entire forests. It was first introduced to North America in 1876 in the Japanese pavilion at the Philadelphia Centennial Exposition. Make certain to consult your state’s environmental conservation or natural resource management agency to determine which herbicides are legal for kudzu control in your state. You need to remove this to kill the plant. For homeowners, it is crucial to identify and control kudzu early because once it has taken hold, it is very difficult and lengthy to eradicate. Root Crown Method: Follow the young or resprouting stem of the plant to the root. It engulfs even man-made structures such as power lines, road signs, and buildings. This growth tactic appears to aid the plant in the formation of lianas in forested areas. Management Strategies: DO NOT PLANT KUDZU. In some areas, kudzu blossoms have been prized for their use in making kudzu blossom jelly and jam. Stems are also hairy. Each pod contains from 3 to 10 kidney bean-shaped seeds, of which only 1 or 2 seeds are viable. Kudzu is an invasive plant species in the United States.Its introduction has produced devastating environmental consequences. Perennial, deciduous, semi-woody climbing vine; stems are yellow-green and are covered with golden and silver hairs. Use a shovel or pickaxe to dig the area until you see new bud growth. Nodes and crowns are the source of all kudzu vines, and roots cannot produce vines. Without the crown, the plant would die. “See this? The vine can grow up to 100 feet long into the crown of the tallest trees, depriving them of light and choking them, or making them collapse from the sheer weight of the vine, which can reach ten inches in diameter. For more information, please visit iMapInvasives. Kudzu produces clusters of 20 – 30 hairy brown seed pods, 1.6 – 2 inch (4 – 5 cm) long pods. All of the kudzu debris should be removed and burned to prevent it from re-growing. Follow stems to where they sprout from the ground and dig down until you find the root crown -- the area from which the roots radiate. Apply a 50% glyphosate solution or 50% triclopyr solution to the main root crown and any below ground runners. As many as thirty vines may grow from a single root crown. It’s important to keep a close eye on the area for a couple of years before you declare victory. The central leaflet has three lobes, whereas the two outer leaflets have only one to two lobes. Each seed pod contains three to ten seeds. Kudzu was heavily promoted in the early-1900s when the government paid farmers to use the vine for erosion control (more than a million acres are estimated to have been planted as a result) and as a drought-tolerant, nitrogen-fixing legume (capable of bacterial growth with stem and root nodules converting free nitrogen to nitrates, which the host plant utilizes for its growth in low nitrogen soils) for livestock feed. Kudzu roots are fleshy, with massive tap roots 7 inches or more in diameter, 6 feet or more in length, and weighing as much as 400 pounds. She works as a freelance copywriter, editor, translator, and content strategist. Kudzu is native to Asia, particularly China, Japan and Korea, and has been used in Eastern medicine for centuries. Most herbicides, including glyphosate as the active ingredient (Roundup), have only limited effect and only when the plants are fairly small. Learn tips for creating your most beautiful (and bountiful) garden ever. As heavy infestations of kudzu can completely cover trees of almost any size, kudzu lianas can both fell trees from their extreme weight or nearly eliminate light availability within the forest canopy, weakening or killing shade-intolerant species, particularly pines. The formidable tubers continue to regenerate new growth unless you use a chemical herbicide. As you walk closer to the vines you will locate intertwined clusters of them. Kudzu lianas can cause weakened trees to fall from the weight of the overgrowth of vines or by pulling down trees attached to the liana when one weak tree succumbs to the weight of ice freezing onto the tree and/or the vines. Mowing of trailing vines and root crowns every two weeks may take up to ten years to eradicate small, immature patches of kudzu, assuming that all root heads are mowed. They do this at intervals on the vine of roughly 1-2 feet. An established kudzu plant grows quickly, up to one foot per day up to 100 feet long. to climb to the forest canopy to get access to light. It’s related to five species in the genus Pueraria (P. montana, P. lobata, P. edulis, P. phaseoloides and P. thomsoni). Crowns form from vine nodes that root to the ground, and range from pea-size to basketball-size. to climb to the forest canopy to get access to light. Kudzu populations spread both asexually and by seed germination. Mechanical harvesting of kudzu foliage limits the production of new food reserves by reducing photosynthesis; regrowth helps to deplete starch stored in the root system. In Maui, kudzu threatens nearby taro loi and natural areas. Kudzu roots are fleshy, with massive tap roots 7 inches or more in diameter, 6 feet or more in length, and weighing as much as 400 pounds. As many as thirty stems may grow from a single root crown. During the Great Depression, thousands of acres of kudzu were planted by the Civilian Conservation Corps for hillside stabilization projects. Kudzu has dark-green, hairy, alternate, compound leaves, 2 – 8 inches (5 – 20 cm) in length with three oval- to heart-shaped lea… Vines can grow up to 30 to 100 feet (9 – 30.5 meters) per year. Kudzu was widely promoted as a drought-resistant, high-nitrogen forage crop. Areas of more than 100 acres (40 hectares) with 1 – 2 plants per square foot, or 40,000 to 85,000 plants per acre (107,000 to 215,000 plants per hectare) can be found in the American South. If the root crown is still intact or any vines are left in the soil, kudzu will grow back. In areas where the plant cannot be tolerated at all, kudzu control is basically kudzu eradication. It establishes very quickly and aggressively invades open areas, forest edges and agricultural fields. The trailing, prostrate stems found in open areas die back to the root crown following the 1st frost. These government-sanctioned uses of the vine, combined with its innate, aggressive, range-expansion capabilities resulted in a rapid spread of kudzu throughout North America. This is the root crown. 400 pounds. Research in the 1930s examined optimum planting density, fertilization (Ahlgren, 1956), and the optimum time of mowing to maximize yield without depleting the kudzu root starch so much as to prevent regrowth each spring (Sturkie and Grimes, 1939). It has been observed that kudzu in North America is more likely to grow asexually than by setting seed. If there is a such thing as a super weed, this is it. Do not leave it bare because this increases the risk of kudzu reestablishing itself. To stop new kudzu vine growth, cut just below the root crown and remove the root crown from the soil. This approach is moderately successful. Kudzu is most readily identified by its growth habit of quickly and completely covering surrounding vegetation and structures. The flowers are typically red, purple, or magenta with a strong, grape-like aroma; pink or white flowers occur occasionally. For a long time, it was viewed as a “wonder plant”—in the 1930’s the government paid landowners in the southeastern United States eight dollars per acre to plant kudzu for erosion control and cattle grazing. It was estimated in 2001 that kudzu covers more than an estimated five million acres of forest land, which is more than five times the size of Rhode Island. Absence of data does not necessarily mean absence of the species at that site, but that it has not been reported there. For kudzu vines that are climbing trees, walls, other plants, fencing, or even trellises, cut them off and remove them manually or using garden shears. You can also remove the root crown. Kudzu is reported as one of the weeds of greatest concern in the Great Smoky Mountains National Park and is said to be capable of replacing native vegetation through rapid vegetative expansion (Loope 1992). Kudzu sends out new growth from the root crown but not the entire root below it. Introducing "One Thing": A New Video Series, The Spruce Gardening & Plant Care Review Board, The Spruce Renovations and Repair Review Board. Kudzu can grow up to 60 feet or more in one season and its roots can reach 14 feet deep. It’s the very top of the root system, the point from which all new growth sprouts. The long kudzu fibers are also used in basket making. Crowns form from multiple vine nodes that root to the ground, and range from pea- to basketball-sized. 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. Defoliation forces the plant to call on root starch reserves to resume foliage growth activities, helping to diminish reserves of starch and prevent storage of new reserves. For this reason, kudzu vine control may start with mechanical means but has to end in chemical treatments to fully kill all the plant … than around bare tree trunks. The older the crowns, the deeper they tend to be found in the ground. Kudzu is an herbaceous to semi-woody, climbing or trailing, nonnative, deciduous, perennial vine or liana (a vine that is rooted in ground-level soil and uses trees and other vertical supports (telephone polls, buildings, etc.) Kudzu puts out 5 runners from each crown so if you start with one you will have five vines. Kudzu can now be found in 30 states from Oregon and Washington State to Massachusetts, particularly infesting states from Nebraska and Texas eastward most heavily; the vine is most common in the South. Kudzu mainly occurs in the southeastern United State but has also been reported in northern states like Pennsylvania. Trailing stems in open areas tend to die back in the winter. Kudzu is a perennial invasive vine that was introduced in the United States from Asia in 1876. Kudzu root extract suppresses voluntary alcohol intake and alcohol withdrawal symptoms in P rats receiving free access to water and alcohol. For information regarding appropriate use of herbicides against kudzu and other invasive plants, please consult The Nature Conservancy’s Weed Control Methods Handbook. It is only necessary to use some method to kill or remove the kudzu root crown and all rooting runners. Seeds deposited below the vines in the seed bank may take several years to germinate. There is some indication (not yet definitively proven) that wildfire (or controlled burn) soil heating may promote kudzu seed germination by scarifying the seedcoat which would allow penetration by water to allow for germination. Kudzu produces long, hairy vines from a central root crown. Kudzu is mainly found in non-cultivated land such as abandoned fields, in ditches, and along roadsides. For this reason removing the root crown is crucial. Because of its underground root crowns, kudzu can escape fire damage. Cut the Vines. Kudzu grows well under a wide range of conditions and in most soil types. If the root crown is still intact or any vines are left in the soil, kudzu … Its massive tap roots can weigh more than 45 kilograms, with up to 30 vines growing from a single root crown. To reach additional light, the vines climb existing vegetation and hard vertical surfaces. Kudzu is weakened over time by repeated regular defoliation. If you remove the crown, the vine will die and there is no need to dig up the remaining taproots which can be quite long. It also has very deep taproots that are almost impossible to dig out entirely. Vertically climbing vines develop thick bark and can reach diameters greater than 0.8 inch (2 cm), aiding in overwintering. Kudzu has dark-green, hairy, alternate, compound leaves, 2 – 8 inches (5 – 20 cm) in length with three oval- to heart-shaped lea… It overgrows anything in its way, blocking the sunlight, and depriving plants of water and nutrients so they die. And, equally important, replant the area with a desirable landscaping plant to fill the space. The more mature the population, the more difficult eradication becomes as a result the numerous crowns and the large rhizome system that can store significant amounts of starch to feed the plant. There are two different mechanical ways how you can tackle kudzu: above ground and below ground. Any crown left behind in soil can resprout and renew the plant. Kudzu spreads primarily through runners, rhizomes, and vines. But kudzu was the plant version of a Trojan horse of the worst kind. Kudzu develops a huge taproot of up to six feet long, which alone can weigh up to 400 pounds. The WORST weed ever. A well-known example would be common wild grape). Both require diligence and persistence. Vertical kudzu vines in full sunlight produce flowers in late-summer; horizontal vines seldom produce flowers. It is a highly invasive species that smothers other vegetation, including native plants. In any event, it’s a good idea to familiarize yourself with its characteristics. It has been spreading rapidly in the Southern United States, "easily outpacing the use of herbicide spraying and mowing, as well increasing the costs of these controls by $6 million annually". It may also be a benefit below forest canopies where light is dim by increasing the surface area of leaves receiving sunlight. The smell of the flowers is sometimes likened to grapes. In northern states, the horizontal vines in the open die back to the root crown after the first frost, but the root crowns survive. The use of intensive conservation grazing by herbivores such as sheep or goats can help control young, tender kudzu growth and make control by herbicides more effective over shorter periods of time by helping to reduce energy reserves. There are a variety of different … Kudzu usually does not flower until its third year, with flowers and seeds forming only on vertical climbing vines. 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). Control costs on power company rights-of-way and transmission equipment have been estimated as high as $1.5 million per year. This can be problematic during control efforts because it can result in the reemergence of the plants years after eradication was believed to have been achieved. This may help kudzu to withstand long periods of drought. You might have to do this weekly during the growing season for as long as two years until it’s fully gone. The critical thing to remember when digging up kudzu root is that you must remove the root crowns. A kudzu invasion can cause several different types of major impacts on native plant communities: it can crowd them out; it can outcompete them; and it can physically crush them. PDF | In 1989, Edward Frankel recorded the distribution of Pueraria Montana var. This is a crown.” The crown is the heart of a kudzu plant. This map shows confirmed observations (green points) submitted to the NYS Invasive Species Database. Kudzu's vertical vines which grow up trees (left & right) can grow to a diameter of 4 … Kudzu thrives through drought and hot temperatures, but continuous removal of all vegetative parts during extreme weather will kill kudzu over time. This is much like using a Weed Wrench, or like using a hammer to remove a nail. Any pieces of root left in the ground will grow and conventional herbicides won't kill it. According to the PMC, kudzu is an effective remedy for stomach issues, relieving indigestion, constipation and even gastritis (x). It has also been discovered in Hawaii and the warm, south-facing growing region on the north shore of Lake Erie in the Canadian Province of Ontario. Even undisturbed plant communities adjacent to an existing population of kudzu can be at risk. Due to the numerous root crowns at vine nodes, eradication of a well-established population of kudzu could take 5 – 10 years of concentrated effort. A second major promotion of kudzu came in 1884 in the Japanese pavilion at the New Orleans Exposition. Alabama Forest Products. It can grow up to 1’ per day and 60’ per season and is also able to produce up to 30 vines from one root crown. The prongs are driven under the kudzu crown, and then the crown is leveraged out. In the 1950s, the Agricultural Conservation Program removed kudzu from the list of species acceptable for use as an agricultural forage crop or soil stabilization plant. Kudzu roots are fleshy, with massive tap roots 10–20 cm (4–8 in) or more in diameter, reaching depths of up to 12 feet in older patches, and weighing as much as 180 kg. While Zev dug out the crown in a matter of seconds, the kudzu campers are charged with a much more daunting task than simply chopping off the top. 2) Herbicides…Tordon and Triclopyr are common herbicides used to treat kudzu. Congress listed kudzu as a Federal Noxious Weed in 1998. As a member of the pea family (Fabaceae), kudzu is in fact edible, which should not tempt you to grow it, ever! Cut the root just below the root crown with a handsaw or, if the root crown is smaller, with pruning shears. Convert kudzu to timber in one year? After the bloom, they become flat, hairy seed pots about two inches long. As kudzu is fire resistant, burning the roots can only weaken the plant but not eradicate it. These physical traits of a kudzu liana significantly impact the ability of native trees to grow and reproduce, increasing the early mortality of native trees, and preventing the establishment of new trees or shrubs in the dim light below the colonized canopy. All of the leaflets are attached to the leaf stem. View abstract. Kudzu produces long, hairy vines from a central root crown. The root crown is a fibrous knob of tissue that sits on top of the roots. The vines have 0.8 – 1 inch (2 – 2.5 cm) flowers on 4 – 8-inch (10 – 20 cm) axillary racemes (short, equal length stalks along a main stem forming clusters of flowers with the oldest flowers toward the base with the newest end of the stalk terminating in one or more undeveloped buds). This has earned it the nickname "the vine that ate the South". Typical kudzu habitats are usually open, disturbed areas such as roadside ditches, rights-of-way, and abandoned fields. Make sure to safely dispose of all the cut plant parts in the garbage. While you can find kudzu vine almost anywhere in the South by taking a drive on a country road, kudzu root is probably most popular by way of a supplement or as kudzu root tea that can be found at most health fo… Lianas are also more efficient at producing starch and sending it to the root system than are horizontal, ground-based vines. The root crown is at the very bottom and should have buds sprouting. Kudzu is an herbaceous to semi-woody, climbing or trailing, nonnative, deciduous, perennial vine or liana (a vine that is rooted in ground-level soil and uses trees and other vertical supports (telephone polls, buildings, etc.) Leaves exposed to open sunlight may be able to maximize photosynthesis, store additional food in kudzu’s rhizomes, and have a competitive advantage over native vegetation. Each vine also has rooting nodes with also set down roots and then send out 5 twisting vines each. They can be very difficult to eradicate in areas that have been invaded by uncontrolled vines. In 2014, the State of New York designated kudzu as a prohibited plant under the state’s Environmental Conservation Law. Once established, kudzu lianas compete with forest trees both for sunlight in the crown and for water and nutrients from the soil. Kudzu has a strong daily leaf orientation capability; by controlling the leaf position as it faces toward or away from the sun, kudzu can control sunlight intensity on the leaflets that are exposed. Kudzu vines can more easily grow around smaller vines such as honeysuckle (Lonicera spp.) Large semiwoody tuberous roots with no vine buds reach depths of three to 16 feet, while the target of control on older plants is a knot- or ball-like root crown on top of the soil surface where vines and roots originate. A well-known example would be common wild grape). Kudzu’s rapid growth rate and its manner of growing over whatever it encounters in its path can also overwhelm native plant communities, also resulting in monospecific stands of the vine. Cut the root just below the root crown with a handsaw or, if the root crown is smaller, with pruning shears. In such settings, kudzu can form large monocultures with thousands of plants per acre. By outcompeting, smothering, and physically removing native vegetation, kudzu damages to lost forest production for southern commercial timber producers has been estimated to be as high as $48 per acre ($118 per hectare) per year. “During the first half of 2006, some volunteers started using the pronged end of the 16″ and 26” hand pronghoes as a crown extraction device. Wild kudzu vines spread by vegetative stems called stolons. Kudzu thrives where the climate favors mild winters (40 – 60°F {4 -16°C}), summer temperatures rising above 80°F (27°C), precipitation greater than 40 inches (101 cm), and a long growing season. This significantly alters natural plant communities and the animals that rely on those natural communities for food and habitat. Unfortunately, there are neither quick nor easy ways to get rid of kudzu—unless you have goats or sheep, which love to eat kudzu. As many as thirty vines may grow from a single root crown (Cacek 1998). The root crown is a fibrous knob of tissue that sits on top of the root (rhizome). Kudzu is considered a semiwoody perennial because it exhibits 2 strategies for overwintering. Mowing is more likely to result in eradication if used with herbicide application. Factors that help determine how invasive kudzu will be in any habitat appear to be climate and availability of light. This ability can reduce leaf temperatures relative to native vegetation and minimize the amount of water lost from the plant by leaf surface transpiration during times of peak sunlight. Kudzu tap roots can grow up to 12 feet (3.6 meters) long and weigh up to several hundred pounds. If a single treatment is all that can be undertaken in a year, it should be implemented in early-fall as foliage starch allocation to the root system replenishing that used for growth during the spring and summer takes place in the early-fall. This mucus helps break down acid found in the stomach. Kudzu can grow amazingly fast – up to 30 centimetres a day and up to 30 metres a season in the southeastern United States. Dormant  viable seeds are unable to germinate until after their seed coats have become water permeable as a result of physical scarification (breaking the seed coat by abrasion or prolonged thermal stress). Each root crown would act like a new plant the following spring. However, that does not mean it cannot pop up in your yard, especially in larger properties with open space or woodland. Follow the vine to the ground and dig there. It does not appear that the composition of the local native plant community has much influence on kudzu invasiveness. During mechanical eradication efforts, all cut plant material should be destroyed by burning or by bagging and landfilling. J Med Food 2004;7:168-79. The crown is a bulb-like feature at the top of the root system which holds the energy of the vine. It isn't called the "vine that ate the South" for nothing. Nadia Hassani has nearly two decades of gardening experience. You can opt-out at any time. Introduction & Distribution  |  Biology & Identification  |  Habitat & Ecology  |  Impacts  |  Control  |  Policy  |  New York Distribution Map. Eradication of kudzu with herbicides calls for frequent defoliation during the growing season, while most of the plant’s energy is devoted to vine production and growth. Dig and cut into the root crown using a pulaski or similar tool. ©Copyright New York Invasive Species Information 2020, New York State's gateway to science-based invasive species information, K-12 Aquatic Invasive Species Education Materials, Walnut Twig Beetle, Thousand Cankers Disease. It girdles tree trunks, and breaks branches and whole trees because they cannot withstand the immense weight. Recently, kudzu root has been used to treat diabetes, alcoholism, menopausal symptoms, and even the common cold! With a growth rate of up to one foot (0.3 meter) per day, simply controlling or managing kudzu can become a “fool’s errand” of never ending activity. Kudzu has alternate compound leaves with three broad leaflets up to four inches across. There is a main crown and then smaller crowns as the stems root at internodes. When broken down, kudzu root has a thick and sticky consistency resembling a type of mucus that naturally coats the lining of the stomach. Bibliography. It appears that this is due to kudzu seedlings being outcompeted by vegetatively produced vines. Kudzu is a fast-growing vine native to the subtropical regions of China and Japan, as well as some other Pacific islands.1, 2 The plant consists of leaves (containing 3 broad oval leaflets), purple flowers, and curling tendril spikes.3, 4 Because the stem grows up to 20 m in length and due to its extensive root system, kudzu has been used to control soil erosion. Kudzu produces long, hairy vines from a central root crown. Remove prior … Kudzu can also be a problem along highway rights-of-way. For this reason removing the root crown is crucial. Kudzu is also known as foot-a-night vine, Japanese arrowroot, Ko-hemp, and “the vine that ate the South.” The vine, a legume, is a member of the bean family. Kudzu (Pueraria montana) is a semi-woody, trailing or climbing, perennial invasive vine native to China, Japan, and the Indian subcontinent.
