To help protect our environment:
Forest gaps and margins, wasteland, roadsides, urban areas, agricultural areas, riparian margins, urban areas, disturbed habitats.
Seeds dispersed by wind and water. Vegetative spread from suckering.
Forms dense stands and suppresses vegetation through allelopathy. May alter nutrient cycling regimes and facilitate establishment of pest plant species.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
Do not attempt to undertake control of this species on Aotea/Great Barrier Island group. Please report to Auckland Council if seen on Aotea/Great Barrier Island group.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
