Cultivation of pasture or native vegetation after mechanical control will help to prevent re-sprouting and seedling establishment. Fire destroys seed in the soil surface and can be used as a follow-up to remove seedlings after other control efforts. Fire may also be used to manage mature trees. Hand grubbing for single plants or small outbreaks, ensure removal of the root system. Biocontrol options are available.
