Densely tufted, deep-rooted perennial tussock <1m high. Leaves Y-shaped in cross section, sharp enough to cut fingers. Flowers (Oct-Feb) in catkin-like spikes, on filaments at end of long, nodding stalks. Distinguished from native species by these filaments, with several coming out of the same point on the stalk.
Poor pasture, scrub, forest margins. Establishes most rapidly on exposed areas of low fertility, drought, overgrazing.
Seed is heavy, so doesn’t spread far.
Forms dense infestations in pastoral areas with poor grass cover. Reduces pasture productivity, is unpalatable to stock. Excludes native grasses.
Difficult & costly to eradicate once established. Interplanting leads to succession, however dense stands delay this process. Best to spray dense patches, replant next winter. Begin at top of slope and catchment. Grazing does not control, only spreads seed. Exclude stock.
1. Dig out (small patches only). Best in summer.
2. Weed wipe spring-summer (300ml glyphosate/1L).
3. Spray spring- autumn, (150ml glyphosate/10L).
Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
