how do get rid of Japanese Knotweed from my garden?

Answer 1

an effective way would be to stick a bamboo cane in the ground so the weed grows up it. put on some thick rubber gloves and get some weedkiller in a bucket. put your hands in the killer and then squeeze the weed with your killer covered gloves. do this all the way from the top to the bottom of the cane, covering all of the weed. the killer will be carried to the roots and kill it slowly. you may have to try this more than once. doing it this way means that you can still have healthy plants next to it as the killer is not applied to the soil. hope this makes sense, so much easier if i could just show you.

Answer 2

Marine Knotweed

Answer 3

Spraying the plant with an appropriate herbicide is the most effective option available, however it can take several years and rarely achieves eradication without mechanical disturbance. Herbicide treatment can give the appearance of control but the rhizome network (roots below ground) may still be viable and disturbing the ground will cause the plant to regrow. Soil movement should not be attempted until no rhizome remains in a viable condition.

Spraying can only be carried out during the growing season when there is green, leafy material present. Herbicide treatments take effect within a few weeks but eradication can take a minimum of two sprays in one growing season to achieve. Often, when a contractor takes control of a site, the working programme is tight and does not allow sufficient time for this method of eradication to be used. Even so, a spraying programme may be an option for weakening the plant before removal or treating regrowth and remaining plants in the spring.

The person who will be undertaking the spraying must hold a Certificate of Competence for herbicide use or should work under the direct supervision of a certificate holder. A Certificate of Technical Competence can be obtained by attending a short course at an agricultural college or similar institution.

A COSHH assessment must be carried out for all activities involving herbicides. Further information on COSHH can be obtained from the HSE and HSENI.

Answer 4

Contavt your local council. There are special steps that have to be followed in removing knotweed. Any roots left in the ground can continue to grow. The only way is to have it specially treated and removed.

Answer 5

Japanese knot weed is a very hard plant to kill and dispose of.. there are not that many chemicals that will touch it.. One that we use is a product called Tordon 22k (Picloram). this usually kills it off for a year or so, but it is likely to come back. don't waste your time with Round-up (glyphosate) or Garlon 4(triclopyr) they will not work..!!! To actually rid your garden of [Jap Knwd] you must remove the soil it is growing in to a depth of 6m.. this is going to be costly, as the plant and soil will both have to be disposed of.. i recommend you contact your local council, and inform them that it is in your garden. they may be able to arrange a specialized contractor to come and remove it.. NB bear in mind this plant is on Britain's invasive plants list along with Giant hog-weed..

With great difficulty, you will have to continue spraying with a systemic weed killer like round up, it could take years to oust it.
I wish you the very best of luck.
