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.
Here are examples of some garden plants that are invasive in certain climates, but there are many others with weed potential that are not included on this list. Check with local nurseries or council if in doubt.
