Himalayan Balsam (Impatiens glandulifera)
March 2023 emerging Himalayan Balsam plants within a riverside woodland floor.

Time to start keeping an eye out for these early signs of Himalayan Balsam as, unlike Japanese Knotweed (Reynoutria japonica), Himalayan Balsam produces viable seed, which is how it spreads. Each plant can produce up to 800 seeds. Himalayan Balsam produces seed pods that ‘explode’, throwing the seeds up to about 7m.
It is vital to stop the Himalayan Balsam plants from producing these seeds, which is why it is important to identify the new plants coming up early on so that you can implement a control programme before they develop flowers and seeds.
Himalayan Balsam is very invasive, it is on Schedule 9 of the Wildlife and Countryside Act (1981), the same list that Japanese Knotweed is on and will very quickly colonise an area and so it is vital to get a control programme into place quickly.
