How to act

Basal barking is an effective treatment for this weed. Care must be taken as this plant can regrow from cut stumps and can sucker a long way from the main plant. Any regrowth can be treated using a follow up foliar spray or hand pulling of seedlings, taking care not to damage any native vegetation.

Refer to Weed Control Methods.
