What you need to know

Although feral olive 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.

Open areas, riparian margins, cliffs, sand dunes, forest gaps and margins, roadsides.

Seeds dispersed by birds and other animals. Vegetative spread from suckering. Human-mediated dispersal through cultivation.

Potential to outcompete native vegetation and suppress seedling recruitment. Increases fire risk.

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.
