What does Japanese Knotweed look like?

Japanese Knotweed is a plant with a notorious reputation for its relentless growth and destructive nature. An unwelcome weed from East Asia, it’s become a serious headache for homeowners and environmentalists alike.

But what does this infamous plant look like, and how can we keep it in check?

What is Japanese Knotweed?

Originally from East Asia, Japanese Knotweed has become a significant cause for concern amongst property owners due to its fast growth and ability to cause serious structural damage. And all in spite of its attractive appearance.

What Does Japanese Knotweed Look Like?

Identifying Japanese Knotweed is crucial in managing its spread. During spring, the plant sprouts red or purple shoots that resemble asparagus. As it matures, Japanese Knotweed develops hollow, bamboo-like stems, reaching up to 2-3 metres high. These stems, which have a green hue and reddish specks, grow in a zig-zag pattern.

In the summer, bees are attracted to its clusters of creamy-white flowers, while in autumn, the leaves turn yellow and wilt. When winter comes around, the stems become brown, dying off but remaining on the plant.

Why is This Plant an Issue?

Japanese Knotweed’s growth can be alarmingly fast, shooting up to 20 cm a day during summer. Its extensive root system can reach up to seven metres in depth and spread outwards by seven metres, damaging building foundations, walls, drains and any other structure in its path.

Its resilience is another significant challenge. Even the smallest fragment of its root has the potential to spawn a new plant. Just the presence of a single plant can be enough to reduce the value of a property.

Japanese Knotweed UK Laws

In the UK, having Japanese Knotweed on your property isn’t illegal. However, letting it spread is an offence under the Wildlife and Countryside Act 1981. Plus, improper management of this invasive weed can lead to hefty fines or even imprisonment.

Should I Try to Remove Japanese Knotweed?

Considering the plant’s persistence, trying to remove Japanese Knotweed by yourself isn’t recommended. Actions like cutting or digging can unintentionally promote its spread, and home treatments rarely succeed in exterminating it entirely.
