Weeds and their spread are usually indicators of nature trying to “fix” itself after mismanagement – overclearing, over grazing and over cultivation/mowing of land.. Weeds hold a purpose in the scheme of things, and usually weed management is about caring for the country and letting biodiversity back into the equation.

It is important to remember that spraying  with herbicides can have a number of undesirable consequences. Other valuable pasture can be affected or killed by the herbicide, and animals/insects  that live with, near and forage off the sprayed weed may not survive inappropriate spraying techniques. Always follow the instructions on the HERBICIDE LABEL and read the MSDS sheet.

Like many of the “daisy” type weeds,  just one or two Fireweed plants,  in one growing season, can create tens of thousands of new plants, if left unmanaged. If Fireweed is growing in or near degraded pastures, roadsides and vacant land, its seed can become air born and travel to neighbouring property on the wind.

Fireweed is an extremely successful “weed”.

I have just spent a number of weeks through this past winter, hand pulling Fireweed from a property in SE QLD.  The hand pulling of Fireweed in early winter can help the spread of any legumes that are competing in the pasture, thus ensuring more soil cover of appropriate pasture species, rather than the weed. The above photo shows  just some of the Fireweed that was removed. It was later burnt to destroy the seed that was on the plants.

Once fireweed has flowered, it has the capacity to produce seed very quickly. If it is hand pulled while flowering, the seed can still develop on the “pulled” plant. This means that once the fireweed is removed from the ground, the plant still needs to be carefully managed, as the seeds begin to mature quickly on the pulled plant, due to the stress of it being uprooted. The seed can then disperse on the wind, unless the plant is destroyed in a way that prevents this.

The best way to hand remove is to pull the whole plant, roots and all from the ground, with as little disturbance to the soil as possible. If the plants are already flowering, removal on a still, non windy day is best, ensuring that as few seed as possible are released into the air or onto the soil. Overseeding the “pulled” area with pasture legumes, native and pasture grass seed or native herbaceous seed to compete with consequent Fireweed seed that will germinate and establish is important. Follow up weeding and pasture management for a number of years/seasons may be required.

Overgrazed pastures and highly disturbed soils can be an excellent “nursery” for Fireweed. Hence, promotion of  suitable groundcover across the infested site and across neighbouring land is essential to Fireweed management. This will ensure that the Fireweed has to compete to survive. I always use gloves when I remove Fireweed, as the palms of the hands (indeed any part of the body that perspires strongly) can allow toxic chemicals into the system.

Here are a few links to help you learn more about FIREWEED, its growth, spread and management…..and please remember – fireweed, because of the way it spreads, can become your neighbours problem, or even the region’s problem, if you chose to allow to let it get out of hand by letting your pasture and roadsides become over infested. Help your local Council out by hand pulling fireweed and fostering low growing native vegetation on the road verges adjacent to your property. This will help the council’s dependence (which currently seems to be the case) on costly herbicide application.

Spraying herbicides should be a last resort. Bluecray does NOT advocate the use of Herbicides, especially when there are other land management practices available, such as increasing groundcover &  biodiversity of vegetation,  decreasing stocking rates in times of climate stress and minimum cultivation of land. Bluecray also advocates reading MSDS sheets, proper calibration of spray equipment and use of the correctly working suitable nozzles and herbicide application rates, if you must spray. ALWAYS READ THE LABEL!!!!!!!!

The above photo (Beechmont Plateau, SE QLD) shows fireweed growing on a property that was overgrazed and mismanaged for many years, much to the owners dismay. They had rented the property out to someone who was ignorant to the problems of fireweed and who repeatedly refused/ was unable  to manage it. Finally the people moved out, and we were all able to go into the paddocks and remove the fireweed.
