This species can form dense, prickly thickets and can spread where stems root at their tips, so management often focuses on preventing movement of plant material and treating infestations in a way that avoids creating new spread points.
1
Treat outliers and small patches
Target isolated plants and small infestations using cut-stump treatment to limit thicket formation and spread into nearby areas.
2
Avoid moving plant fragments
Keep cut material and soil from being carried to clean areas by cleaning down tools, machinery, and vehicles after working in infested sites.
Use chemicals to the label. Always read the current APVMA-approved label before application.
Check permit conditions for your state, as some uses are limited to council or government staff.
