Identification of Himalayan Balsam:
- Reddish coloured stems
- Common on river banks
- Dark green lance-shaped leaves with jagged edges

- Grows up to 2m height
- Dies back at end of growing season
- Produces 2500 seeds per plant each year
- Explosive seed pods
Himalayan balsam plants can produce around 2500 seeds each year. The seedpods open in such a way that the seeds are thrown several metres away from the parent plant, helping the species to rapidly spread – often quoted as 20 metres in all directions per season.
Seeds can also be transported by:
- Water – if parent plant is close to river or stream;
- Movements of contaminated soil;
- Fishermen/walkers picking up seeds on footwear.
If you have concerns over Himalayan balsam on your land, if you are unsure of your legal responsibilities, or, if you would like a quotation for control, please contact one of our specialist surveyors. Treatment costs start at £380.00 + VAT.
