Japanese knotweed is such a good competitor because it forms thick, dense colonies that crowd out any other herbaceous species and is now considered one of the worst invasive exotics in parts of the eastern United States. The success of the species has been partially attributed to its tolerance of a wide range of soil types, pH and salinity. Its rhizomes can survive temperatures of −35 °C (−31 °F) and can extend 7 meters (23 feet) horizontally and 3 meters (9.8 feet) deep, making removal by excavation extremely difficult. The plant is also resilient to cutting since it vigorously re-sprouts from the roots.
