Bohemian knotweed shares some dangerous traits with Japanese knotweed – the plant is exceptionally strong, and the roots can grow through the smallest gaps, causing damage to concrete, drains, mortar, and brick constructions.
It looks incredibly similar to Japanese knotweed but has slightly larger leaves. Both plants have creamy white flowers and heart-shaped leaves. To remove it from site, you’ll need to remove the rhizomes (roots) completely or the knotweed will be able to grow back.
While there have been incredibly few cases of Bohemian knotweed to date, the plant seems to be quicker growing and more invasive than either of its parent plants. Of the few cases so far in the UK, it has been eradicated from gardens via excavation and glyphosate-based spray.
If you suspect you have Bohemian knotweed, please do contact us. Likewise, if you suspect you have Japanese or Giant knotweed, we recommend that you get this treated as soon as possible to avoid any cross pollination and generating a new stand of Bohemian knotweed.
