Invasive species (hogweed, policeman’s helmet, Japanese knotgrass, etc.)

Invasive plant species include hogweed, policeman’s helmet and Japanese knotgrass, the spread of which should be prevented in Finland. The parts of the plant that can spread it (such as seeds, roots) must be packed carefully and sorted into mixed waste. Pack flowers, seeds and roots carefully into a plastic bag.
