Wild Broom

Europe, Asia Minor, Russia

General description

Erect, woody, much-branched perennial shrub <2m tall. Small leaves consisting of 3 softly-haired leaflets <2mm long often shed during summer, new growth occurring during flowering. Bright yellow pea-like flowers (Sept-Apr). Dark flattened pods (Nov-Apr).

Pasture, waste areas, plantations, consolidated sand dunes, gravel pits. Prefers colder climates & areas of high rainfall, acidic soils but never chalks.

Seeds flung from pods as they burst. Also water, on machines, animals, in produce, gravel & mud.

Smothers native vegetation. Unpalatable to stock. Harbours pest species such as rabbits & possums.

Site management

Establish plant is not native broom. Is succeeded in tall canopy habitats by taller native spp. (not in kauri or tänekaha forest). These sites can be left; regeneration can be speeded by slashing, selective spraying or replanting of shade-creating spp. Clear roads, metal dumps or quarries. Maintain pest & livestock control, as it is not browsed as readily as native spp. & recovers faster from browsing.

Recommended approaches

1. In rural areas, report it immediately to the Auckland Council Biosecurity team, who will control it at their expense.
2. Introduce biocontrol agents where possible. Use other methods where broom is of low incidence or poses a high ecological threat.
3. Hand pull or dig out small plants minimising soil disturbance.
4. Cut & stump paint (5g melsulfuron/1L or 50ml triclopyr/1L).
5.Weed wipe spring - summer (200ml triclopyr/1L).
6. Spray Nov-May (100ml glyphosate + 20ml penetrant/10L or 5g metsulfuron + 10ml penetrant/10L).

Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
