Broom description

Broom identification

Cape broom (Genista monspessulana) is an upright evergreen shrub up to 3 m high, but more commonly 1 to 2 m. Young plants are capable of flowering and fruiting at approximately two years old. The leaves consist of three leaflets attached centrally to a short stalk. Leaflets have less hair on the upper surface than the lower surface.

Flax-leaf broom (G. linifolia) can be distinguished by its stalkless or near stalkless leaves, which have rolled edges and are densely hairy on the underside.

Controlling broom

Broom is a weed of national significance and is identified as being invasive, having the potential for widespread environmental, social and economical damage. Landowners and land managers at all levels are responsible for actively managing this weed.

When Cape broom is actively growing prior to pod formation, spray with Grazon Extra at 250 mL/100 L water during spring to mid summer. For an autumn or winter application, use Grazon Extra at 350 mL/100 L water for best results.
