Dueling Deceptive: Unveiling the Differences Between Japanese Knotweed and Bindweed

At first glance, both Japanese knotweed and bindweed might appear as common garden nuisances with their heart-shaped leaves and vigorous growth. But don’t be fooled by their superficial similarities! These two invasive plants have distinct characteristics, and behaviours, and require vastly different approaches for control. So, before you reach for the nearest weedkiller, let’s delve into the world of these imposters and equip you with the knowledge to tell them apart:

Growth Habit:

  • Japanese Knotweed: This aggressive invader stands tall and proud, boasting bamboo-like stems that can reach up to 3 metres in height. It forms dense stands, pushing aside other vegetation in its path.

  • Bindweed: A stealthy climber, bindweed utilizes twining stems to entangle and smother nearby plants, including fences, walls, and even other weeds. It rarely grows taller than 2 metres.

  • Japanese Knotweed: While heart-shaped like bindweed, its leaves are larger, reaching up to 20 cm in length. They have smooth edges and pointed tips, with prominent veins running underneath.
  • Bindweed: Its heart-shaped leaves are generally smaller (5-10 cm) and have wavy or lobed edges. The veins are less pronounced compared to knotweed.


  • Japanese Knotweed: Tiny, creamy-white flowers bloom in late summer, forming clusters at the stem tips. They are inconspicuous and easily missed.
  • Bindweed: Showy trumpet-shaped flowers, usually white or pink, adorn the plant in late spring and early summer. They are much larger and more noticeable than knotweed flowers.


  • Japanese Knotweed: The true nightmare lies beneath the surface. Knotweed possesses an extensive network of underground rhizomes (horizontal roots) that can grow up to 4 metres deep and spread rapidly, even regenerating from tiny fragments.
  • Bindweed: While also having a persistent root system, bindweed’s roots are shallower and less aggressive than knotweeds. They spread mainly through horizontal runners near the soil surface.

Impact and Removal:

  • Japanese Knotweed: This environmental menace can damage foundations, block pipes, and devalue properties. Due to its aggressive nature and complex root system, professional removal using specialist methods like excavation or herbicide treatment is crucial.
  • Bindweed: Although troublesome, bindweed’s impact is less severe than knotweed. Persistent digging, hand-pulling, and targeted herbicide application can be effective control methods.


  • Early identification is key! The sooner you can distinguish between these imposters, the easier and more cost-effective their control will be.
  • Never confuse the two! While bindweed can be a nuisance, it’s no match for the destructive potential of Japanese knotweed.
  • Seek professional help for knotweed. Don’t attempt DIY removal – you risk spreading the problem further.

By understanding these key differences, you can effectively combat these invasive plants and protect your property from their harmful effects.
