Join us for some Himalayan Balsam Bashing!
Himalayan Balsam (Impatiens glandulifera) is an invasive non-native plant that has colonised some of the woodland stands in the Claypits. Balsam spreads exponentially – a single plant can produce 800 seeds disperse over 7m – and can outcompete many of our native species, tending towards monoculture. To control Balsam, we need to ‘bash’ the stems at least thrice yearly.

What is involved
Balsam Bashing involves cutting or pulling up the plant below the lowest root nodule before they can go to seed. If cutting, important to break the root so the Balsam can’t reseed.
What you need
Sturdy footwear (wellies or boots) and clothes you don’t mind roughing it up in.
We will provide the following:
- A yellow vest and gloves.
- Spades and secateurs to bash balsam
- Tea and refreshments
