  • Plan your control program, this will save time and money in the long-run;
  • Consider the impact of your control methods on off-target species, especially if herbicides are used;
  • Ensure machinery and equipment is washed down between sites or prior to contractors leaving site;
  • Get in early;
  • Carefully time your use of herbicide for best results (see Herbicides for Cape Tulip Control for more information);
  • Coordinate your control program with neighbouring landholders where your weed problem crosses property boundaries;
  • Revisit and regularly inspect the site and ensure follow-up is undertaken.


  • Don't introduce cape tulips to cape tulip-free areas (e.g. by failing to wash down machinery and equipment between sites);
  • Don't start your control program without first planning your approach;
  • Don't rely on one attempt at removal - follow-up is essential;
  • Don't rely just on herbicide control, establish vigorous pasture after removal to reduce re-infestation.

Spread of Cape Tulips

  • Cape tulips are spread by movement of seed, corms and cormils caught in farm machinery and in contaminated agricultural produce.
  • The most common method of dispersal is in hay or silage cut from infested paddocks. Cape tulip corms and cormils can also be spread in floodwaters.

Avoid the introduction of Cape Tulips

  • Avoid introducing cape tulips into clean areas, or into areas from which the weed is being eradicated.
  • Implements and vehicles which have been used on infested areas should be thoroughly cleaned on leaving.
  • Ensure that hay is free of cape tulip seed, corms and cormils.
  • See the Washdown Guidelines for Weed and Disease Control for detailed information on how to wash-down equipment and personnel to reduce the chance of spreading cape tulips.

Chemical control

  • A number of herbicides are registered for use on cape tulip in Tasmania. See Herbicides for Cape Tulip Control for more information.
  • The dormancy of corms and cormils can influence the effectiveness of chemical control of cape tulip.
  • In cool summers or where there is a late break to the season, many corms and cormils remain dormant and do not sprout in the autumn.
  • In this case, treatment with herbicide will have to be repeated over several season before there is a noticeable reduction in the appearance of cape tulips.
