Regarding disinfecting or "sterilizing" cuttings for propagation, I have found that such procedures are rarely needed for most plants. The same goes for rooting hormones. These products should be reserved for known difficult species (usually woody plants), or after some indication that they might overcome problems with rot or difficulty in rooting. Not many geophytes are propagated by cuttings. When I worked as Plant Propagator at RSABG for nine years we found that environmental conditions are perhaps the most important determinants in success: rooting medium, climate conditions (mist or fog, temps, air movement etc.), bottom heat, watering frequency, etc. The careful selection of material that is at the proper stage for rooting was often the most notable factor in successful rooting.
