Although shrub balsam is not a legally declared pest plant, it may still be invasive in some situations. Consider lower risk alternatives for your garden, such as native plants.
Coastal areas, disturbed forests, forest margins, scrubland, wasteland, gardens, urban areas.
Seeds dispersed by explosive dehiscence. Vegetative spread from layering and stem fragments, dispersed by water. Human-mediated dispersal through dumping of garden waste and deliberate plantings.
Forms dense infestations, smothering native vegetation and preventing native seedling recruitment.
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.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
