First Signs of Japanese Knotweed

The first signs of Japanese knotweed often appear in early spring when reddish-purple shoots emerge from the ground. These quickly develop into tall, bamboo-like canes with large, green leaves. By summer, the plant forms dense clusters that can overwhelm native species. If left untreated, knotweed can spread rapidly and cause severe structural damage.

  • Spring: Reddish-purple shoots emerge from the ground.
  • Summer: The plant grows rapidly, forming thick clusters.
  • Autumn: Japanese knotweed in flower – White flowers appear.
  • Winter: The plant dies back, but its rhizomes remain active underground.
