I have a white crinum (C. bulbispermum × moorei 'Album'), which has not
flowered for several years. I am reluctant to divide it since I once
read that disturbing its roots at the wrong time can further delay
blooming for several more years (just like its Amaryllis and Sprekelia
relatives).

Does anyone know what is the right time to divide crinums?
