Erect, deciduous shrub <2.5m tall. Stems have numerous curved thorns & bristles. Bright green leaves, 5-7 leaflets, numerous sweet smelling glands. Small clusters of pink flowers (Feb-May) followed by conspicuous orange-red hips.
Tussock grassland, riverbeds, flats, terraces, banks, roadsides.
Seeds spread via birds & water. Can also regrow from root or stem fragments.
Abundant in the absence of competition, changing the native flora composition.
Grazing does not control plant, merely eliminates plant competition. Exclude livestock, maintain rabbit & other browsing pest control. Planting sites can minimise seedling regrowth. Do not replant for at least 4 months after spraying.
1.Dig out small patches removing all root & stem fragments – beware thorns!
2. Cut stump paint summer - autumn (1g metsulfuron/1L).
3.Spray at full leaf stage (5g metsulfuron+10ml penetrant/10L or 60ml Tordon BK/10L).
