The prominence of fireweed in the Camden Haven

Landcare is educating the Camden Haven public on an invasive weed which grows prominently in the area. 

Local Landcare coordinator Stephen Allwood said fireweed (senecio madagascariensis) originated from South Africa and its population in infested areas is dependent on seasonal conditions which varies each year. 

Mr Allwood said the fireweed can quickly establish where ground has been cultivated, disturbed or where ground cover competition is reduced, either in drought or under excessive grazing pressure.

Mr Allwood said the weed can be confused with native senecio species however he said these species are usually found in coastal environments rather than pasture.

The weed is hard to control but the best way to remove fireweed, Mr Allwood said is by hand. 

“When controlling any weed it is best to use a varied or integrated approach and always follow up,” he said. 

“There are a number of chemicals available for control and the choice will depend on if you are spot spraying, foliar spraying or boom spraying.

“However it is best applied before the plant reaches maturity.”

Mr Allwood said maintaining a healthy ground cover on pasture with good grazing techniques will also minimise the spread of fireweed.
