Himalayan Balsam
Himalayan Balsam has become a significant environmental threat to our native flora and fauna.
Himalayan Balsam (Impatiens glandulifera) is an aggressive, fast-growing invasive plant that can quickly take over natural landscapes, disrupting local ecosystems. Originally introduced to the UK as an ornamental plant, this species now thrives in damp environments, particularly along riverbanks and woodland edges. With distinctive pink to purple flowers that appear from late spring to early autumn, the plant can grow up to 2.5m tall, has broad, serrated leaves and produces explosive seed pods that can scatter seeds over 7m, contributing to its rapid spread.
Why Himalayan Balsam is a Problem
- Rapid Growth: It outcompetes native plants for light, water, and nutrients, reducing biodiversity.
- Soil Erosion: When it dies back in the winter, it leaves soil exposed, which can lead to increased erosion along riverbanks.
- Increased Flood Risk: The plant’s dense growth near watercourses can obstruct water flow, increasing the risk of flooding.
- No Natural Predators: Without natural enemies in the UK, Himalayan Balsam thrives uncontested in many areas.
Treatment & Control Methods
Herbicide Treatment
- A herbicide treatment should be applied selectively to reduce regrowth and protect nearby native plants.
- Carried out by trained, qualified operatives following legal and environmental guidance.
- Requires repeated applications and ongoing monitoring for long-term control.
Removal & Disposal
- Mechanical clearance reduces above-ground growth and prevents seed spread.
- All plant material must be removed and disposed of responsibly to avoid reinfestation.
- Site-specific programs are designed to manage Himalayan Balsam over multiple seasons.
Before quoting a treatment or removal and disposal cost we would need to conduct a site survey. Landtech (UK) Limited offer effective solutions for managing Himalayan Balsam. Our experienced team offers a range either physical removal, chemical treatments, and strategic monitoring to prevent the spread of this invasive species.
