Karamu Control Guide
Spread of karamu
- Karamu reproduces by seed, with male
and female flowers occurring on separate plants. Seed is dispersed
mainly by birds, as well as in dumped garden waste.
- The seed appears to be short lived so that a seed bank does not develop in the soil.
and smaller bushes can be hand-pulled or dug out. The entire root system
should be removed, as plants may re-grow from root-stock left in the
- The tops are likely to break off when pulling, so if roots remain in the soil they should be dug out.
- Removed material bearing fruit should be destroyed (burning or bagging) and not dumped.
- Burning will kill the top growth, but even quite small plants can re-grow from the rootstock.
- Under an off-label permit issued by the Australian Pesticides and Veterinary Medicines Authority (APVMA), a number of herbicides can be used to control karamu in Tasmania. See
Herbicides for Karamu Control for more information.
- Herbicides are most effective on smaller plants under 2 metres and on fresh regrowth.
- The cut-paint method provides best control, with seedlings, smaller plants and any regrowth removed manually.
- Follow-up herbicide treatment may be required as plants can reshoot.
