To effectively eliminate Dokudami, a combination of chemical, physical, and biological methods can be employed. Using herbicides that can kill the roots is essential, and soil-based herbicides help prevent recurrence. Applying a generous amount of herbicide ensures it penetrates the underground stems. Lime can also be mixed into the soil for added effectiveness. Physically, pouring boiling water over the plant or using baking soda can help kill Dokudami. Installing thick, non-woven weed control sheets blocks sunlight, inhibiting the plant's growth. Biologically, planting competitive plants like mint, which has a stronger propagation ability, or perennial plants such as Pachysandra and dandelions, can suppress Dokudami. Timing is crucial; removing Dokudami before it fully grows in mid-May and regularly weeding to eliminate new shoots is recommended. Mulching prevents Dokudami seeds from reaching the soil. Combining these methods enhances the overall effectiveness of Dokudami eradication, but caution is needed when using chemicals to avoid harming surrounding plants and the environment. For thorough removal, targeting the underground stems is most effective.
