The Killer Knotweed
Transcript of The Killer Knotweed
Its native home is Japan. How it got here was that in 1825, Knotweed was introduced to Britain by the Victorian's as a sort of decor. They also brought it there to help with erosion. But there are far too many problems with this plant, including that the plant actually CAUSES erosion. Japanese Knotweed's stalks looks much like bamboo, but isn't like it at all. Some pictures: There are many problems with this plant: This is an issue we are currently trying to solve. Made By Jessi Jean and Jennifer Bussiere The Killer Knotweed It causes erosion, despite England's idea of it doing the exact opposite. Knotweed grows through nearly anything, even concrete and rock. Knotweed is growing so much, that it is starting to rule out other native plants in our area. The debris from the plant dying off in winter, falls or is washed in to streams and rivers, and creates blockages, increasing the risk of floods.

Cut plants back to 18 inches. (Be sure to pick up the stalks that are cut off. Put in to a durable black trash bag and dispose of properly in the dumpster.) 2. Simply spray with the herbicide you have chosen. You can try using weed killers and such, but it is very harmful to the Earth, and it doesn't always even work. A DEFRA working group estimated that it would cost 1.5 BILLION dollars to get rid of knotweed along the UK. And the U.S. is even bigger. Can you imagine the money we would need? So the seventh grade team is trying to find a natural cure for knotweed that won't harm the environment, doesn't cost a lot, and is easy. Some people are making baking soda solutions, using vinegar, making a salt solution, and other things too. People have recommended NOT trying to mow this stuff down, though, for it doesn't make a lot of success, causes a lot of pick up (it would be bad to just leave the stalks there), and essentially, can make the problem worse. But don't fret; not JUST our team is working on a solution. People everywhere are trying. It's just the matter of finding something that WORKS. Since, Knotweed's native home is Japan, knotweed's natural killers aren't here, so we have to find something that works just as good. 3. Repeat 1 + 2 three times a year (fall, spring, and summer)......... For 5 years.
