Blackberry is regarded as one of the worst weeds in Australia because of its invasiveness, potential for spread, and economic and environmental impacts.
Blackberry has invaded riverbanks, roadsides, pastures, orchards, plantations, forests and bushland throughout temperate Australia. On farms, blackberries reduce pasture production, restrict access to water and land, and provide food and shelter for pest animals such as foxes.
Chemical control is best between flowering and leaf fall (look for new growth on the tips of canes). Always display a sign after spraying fruit to notify potential berry pickers and avoid spraying fruiting blackberries which have potential to poison native finches that feed on the fruits.
Blackberry control on roadsides and reserves
Blackberries are widespread in the Macedon Ranges and are regularly found on roadsides and private property. Successful control requires a combined effort of public and private landowners.
The Victorian Government can assist private landholders with blackberry control and weed legislation information. The Weeds of National Significance database also offers online resources such as weed control manuals and distribution maps.
The use of herbicide to control blackberries requires an Agricultural Chemical User Permit.

Picking blackberries on roadsides
Blackberries and other fruits should never be picked from roadsides for eating purposes. Vegetation along our roadsides may have been sprayed with herbicide and may not be safe for consumption.
We require all weed contractors to place signage in areas where weed spraying has been carried out during the fruiting season, however, Council and contractors cannot prevent the unauthorised removal of these signs.
