In many cases, rot starts from pruning cut surfaces ; it may lead to hollowing out of the trunk, and sometimes result in trees falling. We surveyed tree specialists in Japan as to whether or not they applied medicated wraps to pruning cut surfaces, and the type and effectiveness of any that they used,in order to test and compare these. The tree species that we tested, the Somei yoshino cherry genetically, shows small variation between individuals in its reaction to pruning, and is prone to rot at pruning cut surfaces.We found that even in the Somei yoshino cherry trees, skillful pruning did not result in wood discoloration even if medication was not applied to the cut surfaces, but medication that does not kill living tissue was more effective in preventing rot. We also found that medication that is strong enough to kill living tissue tends to discourage formation of calluses but also promotes discoloration of wood.
