WEEDS TO WHACK

You can help our catchment by knowing about local weeds and removing them along the creeks or containing and managing them in your garden.

A weed is a plant growing where it’s not wanted. That doesn’t mean it’s bad, just bad here. Some weeds can be beautiful. In the suburbs, where most weeds have escaped from gardens into the bush or along waterways, many were once highly-prized.
