General description

Thorny, much- branched, deciduous hedge plant <10m high. Stiff spines on stems. Triangular, hairless leaves have 3-7 deep lobes & are often eaten by pear slugs. Covered in sweetly-scented white or pink flowers (Nov). Shiny, round, crimson berries.

Hedgerows, roadsides, old house sites. Prefers distinct seasons & cold winters.

Seeds spread by birds & probably possums.

Forms thick, impenetrable stands that displace native species. Host for fire blight disease.

Site management

Plants prefer disturbed soils, are slow to die & decompose. Avoid temptation to clear, burn or otherwise disturb soil. Maintain humus & groundcover. Plant dense spp. where possible to minimise seeding.

Recommended approaches

1. Dig out small plants.
2. Cut & squirt make 1 cut per 100mm stem diameter & fill each cut with 2g metsulfuron (dissolved in approx 50ml water) All year round.
3. Cut & stump paint autumn - winter (5g metsulfuron/1L).
4. Spray at full leaf & active growing stage (Nov-Mar) only (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.
