Many plants that have been introduced into Australia since European settlement have become weeds. Some native plants removed from their natural habitat have also developed invasive tendencies. All garden owners, but especially those living near bushland, should take responsibility for ensuring that garden plants aren’t able to escape into the bush. For more information visit

To minimise the risk of weed invasion:

●  Avoid growing plants with weed potential.

●  Avoid growing weeds with fruits that attract birds.

●  Don’t dump garden refuse or lawn clippings in the bush.

●  Don’t overfertilise or allow fertiliser nutrients to run into bushland or streams.

●  When walking in bushland, try to stay on the cleared pathways.

●  Prune free-seeding plants (such as agapanthus) immediately after flowering.
