Shrub Balsam

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.

Site Management

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.
