In the clip: The municipal ecologist guides you in how to get rid of giant balm.

Giant balsam is an annual, so-called invasive species.

- Each plant can explosively spread 400 seeds per season, so a large population of giant balsam means that they spread very quickly over a large area.

In addition to the plant reproducing very quickly, it is also so large that it easily shadows out other flora.

What is the worst thing that can happen if you let it grow?

- It is that we lose a lot of our biological diversity in flora and also pollinators that are bound to certain vascular plants.
