Controlling invasive species should continue cautiously in autumn
Proper handling of invasive species and garden waste helps prevent the spread of harmful plants. In autumn, it is especially important to pay attention to the spread of Himalayan balsam seeds and the rats attracted by fallen apples on the ground.
When doing autumn garden work, it is important to handle invasive species and other garden waste correctly. For example, efforts to control Himalayan balsam, a harmful invasive species, should stop once the seeds have formed after early August. Controlling it too late can spread the seeds into the environment and make the problem worse.
Rugosa roses and other woody invasive species must be taken to a collection point designated for woody invasive species, such as Kiertokapula’s Karanoja waste treatment facility. Invasive species must never be taken into nature or handled in a way that could allow them to spread to new areas. For detailed instructions on handling and delivering invasive species waste, see Kiertokapula’s website.
Ordinary garden waste can be composted in a properly maintained compost. Fallen apples from fruit trees should also be collected regularly. Apples left on the ground attract rats and can increase the number of pests in yards.
If you notice invasive species on city-owned land, you can report it through the online feedback service.
