Free Japanese Knotweed Identification

Japanese knotweed (Fallopia japonica) is the most invasive non-native species in the UK. It was initially introduced from East Asia in the 19th century as an ornamental plant. Nowadays, it is a significant nationwide problem causing £m’s every year through structural damage, property devaluation and harm to the environment.

Where Does it Grow?

Waste land, railway sidings, roadsides, verges and riverbanks.

Why is it a Problem?

  • Its aggressive growth can penetrate small cracks in concrete, drains, paths and other structures, causing extensive damage if left untreated.
  • Reduces property value.
  • Difficult to obtain a mortgage without a Japanese knotweed management plan in place.
  • Challenging to remove due to highly invasive rhizomes that can lie dormant underground for up to 20 years. A tiny particle of rhizome left behind can spawn a new infestation.
  • Harmful to biodiversity by starving the local eco system of sunlight and nutrients.

Accurately identifying Japanese Knotweed is crucial for both environmental welfare and property protection. The Knotweed Specialists offers a professional survey, using advanced technology and techniques to diagnose and determine the extent of the infestation accurately. Knotweed roots are particularly challenging due to their strength and depth, making early identification and expert management essential for effective control and removal.

What Does Japanese Knotweed Look Like?

At the start of the growing season, the plant produces reddish shoots resembling asparagus. From them, strong, red-speckled stems grow with large heart-shaped leaves growing in a zig-zag pattern. In late summer, masses of small creamy-white flowers grow on panicles. Eventually, the leaves turn orange and the stems become dry and brittle as the plant dies back during Autumn.

How Does Japanese Knotweed Spread?

Japanese knotweed spreads through its powerful rhizomes. A small fragment of rhizome can spawn to produce new growth. Although it does produce seeds, these are rarely viable as only female plants were introduced to the UK.

Japanese Knotweed Growth

Japanese knotweed is a perennial that dies back during the winter months, using its undergrounds rhizomes to survive in the cold weather. In fact, Japanese knotweed is unusual because although it’s upper leaves and stems retract, the plant continues to grow below ground during winter. It has powerful rhizomes that store nutrients and feed the roots all year.

Misidentification could result in ineffective treatment, legal liability, or fines if the plant spreads.
