How To Identify Japanese Knotweed

Japanese Knotweed HouseThe best time to spot Japanese Knotweed shoots is during early autumn or summer. The plant almost looks asparagus like with fat purple or reddish shoots than can grow up to 2cms per day, they have a pink bud and generally have green leaves that are shaped like hearts or shields. At the peak of their power the Japanese Knotweed stem can reach up to 3 meters in height and the stems will have purple speckles with the leaves on each side. When they bud in late summer you will see a creamy white coloured flower. The roots of the knotweed may be living unground but laying dorment during the winter months. If you have Knotweed it can be incredibly hard to get rid of and you will need to put a Knotweed removal plan in place.

How Dangerous is Japanese Knotweed?

Japanese Knotweed can cause extreme damage and harm to property and vegetation but it's not poisonous to people or animals, some grazing animals can even eat it! The plant draws all the nutrients from the surrounding area and is strong enough to break through concrete, but it's not toxic in anyway.

Japanese Knotweed Removal Cost

The cost of removing Japanese Knotweed varies massively dependant on the amount of land that you have affected and the type of solution that will be required from a simple herbicide programme to a full excavation of the area. The price can typically range anywhere for a small herbicide treatment at around £2,000 to a very large full excavation and disposal at £200,000 which is of course unlikely. As another example, a large herbicide treatment would be around £4,000-£6,500.

Will Japanese Knotweed Affect My House Price?

Simply put, yes. People don't typically want to purchase a property affected by Knotweed as they will need to put a treatment plan in place. Japanese Knotweed can very quickly damage property walls, structure, block drians and cause all sorts of havoc which could be very costly to the property owner.

How Long Does It Take To Get Rid of Japanese Knotweed?

It can take up to 5 years to completely remove any trace of the Japanese Knotweed using treatments. There are ways in which you can immediately get rid of Japanese Knotweed, however, but it involves completely excavating it from the affected area which can be a tricky task due to the size the plant can get to.
