Why does burdock stick

Spiny cocklebur is unmistakable with its stout, forked spines at the base of each leaf. Often the vicious burs form tangled clots in the fur of animals, and must be cut out of the hair. In fact, these remarkable burs have enabled the cocklebur plant to hitchhike all over the world. An assortment of prickly cockleburs Xanthium strumarium. Shoes and socks after walking through a field of cockleburs. Cocklebur Xanthium strumarium ; B. Burdock Arctium lappa ; C. Bur Clover Medicago hispida.

The tenacity of common burdock Arctium minus was described in an article by J. Raloff in Science News Volume , Burdocks are well-known for their ability to stick to bare fingers, but actually trapping an animal was unheard of.

One of the birds was rescued, but the other three were so securely snared by the hooked prickles that they died right on the plants. While burdock root may pick up heavy metals from contaminated soils, others agree it may also a potent detoxifier of heavy metals in human bodies.

Burdock is a biennial plant, meaning it has a two year growing cycle. In the first year, leaves and a rosette are formed. In the second year, it flowers, goes to seed, and then dies. To get rid of this plant, we have to focus on its main way of spreading itself, through the burrs. If you enter or maintain a site where you find burrs, find some way to easily collect and remove as many as possible prior to sprouting perhaps an old mop head dragged along the ground after removing plant parts and picking up the largest burr clusters.

Do not compost them. The most important part of eradicating burdock comes with the second year plants. Remove all flowering heads from the plants so they have no way of going to seed. If you do not want to disturb the earth by turning in the soil, burdock can be managed by cutting and removing all flowering tops. This low-impact method requires much more vigilance, however, and can take a few years until the plant exhausts its energy and the seed bank has diminished.

If your site is so overrun with burdock that none of the above methods are sufficient, very thick sheetmulching with landscaping fabric, several layers of cardboard, and woodchips may suffice, but disturbing the soil after sheetmulching breaks down may bring the old seedbed to the surface.

Another method of maintenance is through improving soil health and nutrient balance. McCaman says burdock grows in soils with very high levels of iron and sulfate sulfur and very low levels of calcium and manganese. Burdock is fantastic, but it can be a great burr-den if you fail to be vigilant in your orchard space.

But did you know that the Burdock plant is also the inspiration behind Velcro? He and his dog had been traversing riverbanks where Burdock typically grows wild it does well in disturbed habitats where it can self-seed, and propagates its seeds through burrs that get stuck and distributed by the fur of passing animals.

De Mestral wondered how the tiny hooks of the cockle-burs the seed packets produced by Burdock, which are covered with stiff spines were sticking to him. De Mestral was inspired to model the configuration for use in clothing.

As the host continues on its way, the burr hangs on until the host deliberately removes the burr or accidentally brushes against a surface that dislodges it. The burrs turn the seed pod into an undiscerning botanical hitchhiker. Beside above, what kind of plant is Burdock?

Burdock , genus Arctium , also spelled burrdock, a genus of biennial plants in the Asteraceae family, bearing globular flower heads with prickly bracts modified leaves. Burdock species, native to Europe and Asia, have been naturalized throughout North America. Large, wavy, heart-shaped leaves that are green on the top and whitish on the bottom makes identifying burdock easy. Leaves can grow to 50 centimetres in size.

If you have areas of pure sand burrs , use a torch to burn them up. You need to burn the seeds to ashes. For mixed areas, you are on a journey. If you burn them in in a small fire it will make the shells to open up and the seed to germinate. If you burn them use a propane torch to get it really hot to kill the seeds. Did you know that cockleburs Xanthium genus , those annoying burs that stick to your clothes and scratch your skin, are toxic if consumed?

Most people are not in the habit of consuming the prickly, spiny seed pods, but they can be incorporated into animal feeds and hay.
