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.
