What does it look like?
Why is it a problem?
Seeds and offset bulbs ensure distribution. It also tolerates hot and cold, wind, semi-shade, damp heavy soils. It’s intolerant of strong competition for space and heavy shade. It forms dense mats in winter/spring in disturbed sites, discourages native species from establishing.
It’s likely to invade disturbed forest and shrubland, sides of streams, herb fields, bare land, especially after spraying or other clearance to bare land
Control methods
Physical control
Dig out small patches (all year round) and dispose of at refuse transfer station.
Herbicide control
Overall spray using metsulfuron-methyl 600g/kg (3g/10L). Note: Metsulfuron overspray will kill other (desirable) broadleaf plants and has residual activity in the soil which aids in killing below ground parts.
Spraying with glyphosate only gives plant more room to expand. Better to overplant with taller species. In regenerating habitats, often better to leave altogether to minimise disturbance.
CAUTION: When using any herbicide or pesticide, PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
