You can cut down the stems anytime after the flowers are finished--in fact,
it's a good idea to do it, so the plant won't put any energy into making
You should not cut back the leaves at all. You should wait until they turn
brown and wither before removing them. As a new gardener, this used to
bother me, but I soon learned there are lots of other things to do and turn
my attention to, and before you know it, it will be high summer and the
foliage will be gone.
You can plant perennials around the bulbs, so that their foliage will help
distract from the fading bulb foliage.
