Rooting and death of vegetative tip cuttings of C. mitchellii, taken from softwood, semi-hardwood and hardwood material, were examined using formulations of auxins (IBA and NAA) at three air temperatures (20 deg C/16 deg C, 25 deg C/20 deg C and 28 deg C/23 deg C; day/night). This species was easy to propagate, particularly if softwood material were used or cuttings were treated with an IBA-based formulation. Formulations containing NAA should be avoided as they result in few rooted cuttings and a high incidence of cutting death. Air temperature had no significant impact on rooting under conditions of high relative humidity and rootzone heating.
