Montbretia out competes native plants by growing in thick clusters and spreading via corms. It can be removed via physical excavation or controlled via herbicide treatment.

Physical removal requires the excavation of the plants and also the surrounding soils which will contain the corms released by the plant. If the surrounding soils are not removed corms located within the soil will repopulate the area with further Montbretia plants. The infested soils are then sent to a licensed landfill as controlled waste.

Chemical treatment provides a cost effective solution in eradicating Montbretia. Herbicide treatment takes place in the early growing season prior to the plant releasing its corms. Subsequent visits need to be undertaken in following years to treat any corms which try to reestablish the area.
