FAQ of giant knotweed

What is giant knotweed?

Giant knotweed (Fallopia sachalinensis) is a vigorous, invasive plant that can grow up to 10 feet tall and spread rapidly by underground rhizomes. It is native to eastern Asia and was introduced to North America and Europe as an ornamental plant in the late 19th century. Giant knotweed is now considered a noxious weed in many countries, including the United States, Canada, and the United Kingdom.

What are the signs of giant knotweed?

Giant knotweed can be identified by its bamboo-like stems, which are hollow and have purple-red streaks. The leaves are heart-shaped and arranged in a zigzag pattern along the stem. In the fall, giant knotweed produces small, white flowers.

How does giant knotweed spread?

Giant knotweed spreads by underground rhizomes, which can grow up to 60 feet long. The rhizomes can also break off and float in water, which can help the plant spread to new areas.

What are the problems caused by giant knotweed?

Giant knotweed can cause a number of problems, including:

• Damage to infrastructure: Giant knotweed can damage foundations, walls, and other structures.
• Suppression of native plants: Giant knotweed can outcompete native plants, leading to the loss of biodiversity.
• Flooding: Giant knotweed can clog waterways, increasing the risk of flooding.
• Health risks: Giant knotweed can be a health hazard, as it can release toxins that can irritate the skin and eyes.

How can I control giant knotweed?

There are a number of ways to control giant knotweed, including:

• Cutting: Cutting giant knotweed can help to slow its spread, but it is not a permanent solution. The cut stems will resprout from the rhizomes.
• Herbicide treatment: Herbicides can be effective at killing giant knotweed, but they must be applied correctly and repeatedly.
