Weed management in the City of Campbelltown is an ongoing effort.
Weeds, like any plant, are either annuals or perennials. By learning to recognise which group your weeds fall into, you can learn to deal with them effectively
Annual weeds complete their lifecycle within a year and rely on setting seed to establish the next generation, so if you can stop them seeding, eventually you can get rid of the weeds.
Examples of annual weeds include mallows, (Malva sp.) stinging nettles (Urtica dioica), capeweed (Arctotheca calendula), and winter grass (Poa annua).
Perennial weeds are more of a challenge because they keep growing year after year, flowering and seeding as they go. Examples of perrenial weeds include couch grass (Cynodon dactylon), kikuyu grass (Pennisetum clandestinum), field bindweed (Convolvulus arvensis), dock (Rumex sp.) and the perennial grasses, phalaris (Phalaris sp.).
Many perennial weeds have an underground storage organ - a bulb, rhizome, stolon, or even just a long, fleshy taproot - and if you don't get it all out, the plant will come back.
For more information on garden weeds, their potential to become bushland invaders and measures to control them see Council's Weeds booklet.
A particularly nasty weed that is prevalent in the Campbelltown Council area is Caltrop.
In 2012 the Campbelltown Friends of the Environment group received a grant from the Adelaide and Mt Lofty Ranges NRM Board to share knowledge about the noxious weed Caltrop. They organised a community workshop and developed signage that can be seen along the linear park asking people to report any occurrences of Caltrop that they see.
Caltrop is a declared weed under the NRM Act 2004 which means that wherever it is found the land owner must control it. Council takes this responsibility very seriously and if you see an occurrence on a road verge or in a park please report it to council at your earliest convenience on 8366 9222 or at email@example.com to allow it to be eradicated as soon as practicable.
For more information on Caltrop please see the fact sheet here.
