When I receive new divisions I soak them in a container of warm water with; physan, superthrive or kln (to help with roots) and I also add a tablespoon of honey per 3 liters of water...or just slightly less than a tablespoon in a half gallon. The water needs to be room temperature to enable the roots to easily take up the nutrients. Any plant coming into your collection will also need to be evaluated for possible bugs, and if needed you can also add a systemic bug killer into the soak. Others have different methods...and after awhile you will develop your own mixtures as well. No one thing works for everyone...and sometimes what has worked in the past has to be changed up when bugs become immune to what you are using.
