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.

Physical removal

  • Seedlings 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 ground.
  • 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.

Chemical control

  • 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.
