What does it look like?

Cotoneasters are long lived, evergreen shrubs up to approximately 3m tall. Young shoots with pale downy hairs mature into arching red-brown stems. Leaves are shiny with soft shaggy hairs above and white-grey hairs underneath. Flowers are small, white and borne in clusters. Fruit are red berries 7-9 mm diameter, with two or three seeds per fruit.

It inhabits open scrub and coastal forest, lava flats, cliffs, forest and river margins, roadsides and track margins, grasslands, plantation forests, wastelands.  A wide range of soil moisture is tolerated but it prefers free draining conditions.  Salt spray, frost and semi-shade are also tolerated.

Why is it a problem?

Cotoneaster tolerates grazing, damp and drought conditions, temperature fluctuations, and a range of soil types. Highly viable and long-lived seeds, combined with early maturity and the formation of dense stands means that cotoneaster outcompetes native shrub species in wide range of habitats.

Control Methods

Physical control

  • Dig out small plants and leave to rot down.

Herbicide control

  • Cut and stump treat with metsulfuron-methyl (600g/kg) 5 g/L or picloram gel.
  • Spray with metsulfuron-methyl (600g/kg) 5g/10L + penetrant  during summer-autumn.
  • Check regularly for newly germinated seedlings and control.
