(something like removing an eye from a potato you are going to eat for dinner), washing the wound with alcohol to remove the slime exuded by the tuber, packing the wound with sulfur, and replanting the tuber. I may confirm it works well with many species of Arisaema tubers. Cutting a tuber in many parts ( remember to sterilize the knife before each cutting ), leaving at least two buds (eyes) on each portion, saving the centre with another bud attached. I never washed with alcohol but always covered the wounds with sulphure powder and stored the cuttings for some days in dry conditions to let them dry well on wounded surfaces. Then I planted the cuttings and got a growing rate about 80% with Candidissimum ( and other species of section franchetiana ), lower rates (about 50%) with Nepenthoides. I was pushed to try by a friend who propagates them by cuttings in U.K. and forced to do so when I found some tubers with small wounds or rotting points when lifted from ground, it usually happened in Autumn this the reason why I didn't immediately replant the cuttings. By the way Zantedeschia tubers don't need cutting with a blade but it is enough to brake by hands the tubers ( coloured and hybrids ) or rizhomes ( aethiopica ) and let them dry in cold dry place with rich flow and change of air to avoid mushes. This works better here in late February 15 days before replanting in full ground. Giorgio Northern Italy, zone 7/7,5 ( going to zone 8 )
