I trim lilies to about 5cm on each stem, what's left helps to identify the contents of each pot, trough or bucket holding the lilies. Springtime top-dressing generally frees those stalk remnants as I carefully delve off 4-5 cm of old compost & replace with fresh.
BTW: The 'discarded' stems can be cut into suitable lengths and used to boost the contents of the various 'Insect Hotels' I have dotted around the shrubberies! [The minibeasts happily excavate their way into the pithy stems, ditto with Dame's Violet and Teasel stems - the differing diameters seem to suit different beasties!].
