Question concerning hybrid Lillie's?

This summer i planted 10 hybrid lillie bulbs.They bloomed buitifly and the flowers have faded.Should i cut them back to the ground now or just leave the stims alone?I think they only bloom once per year dont they? I have reallyenjoyed them and want to do whats best now.Thanks in advance for the advice.

Answers:
Cut off the BLOOM but leave the stem until it looks like it's DYING.

Bulbs STORE nutrients for the next season and they need that stem to make them suck up chemicals from the soil.
