What you need to know

Although jointed rush 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.


Wet habitats, riparian margins, wetlands, drains, pasture.


Seeds dispersed by animals and soil movement. Vegetative spread from rhizomes. Human-mediated dispersal through movement of contaminated soil.

Impact on environment

Can form dense infestations and displace native species.


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.
