  If you are in zone 8 or higher just leave them in the ground. But note that not all bulbs are perennial. You increase the chances of them being perennial if you leave the foliage on until it dries naturally, and if you mulch in the winter.
  If you are in zone 7 or lower, you will need to dig and store dahlias, cannas, some gladioli.

  It depends on the genus…
  Bulbs originally from your zone will do well when left in the ground. (I’m in zone 8, and Narcissus sp. and Crocus sp. thrive when left undisturbed).
  On the other hand, bulbs native in warmer areas, like tulips and hyacints, that’s more difficult. They don’t really thrive when left in the ground… year after year I have less flowers (with one exception for the Tulipa genus: T. sylvestris is spreading like mad.) On the other hand… taking them out isn’t much better: even then, the ‘yield’ will be less year after year….

  I know that in Europe, zone 8 is slightly different from the American (it’s wetter here…), and in zone 8 I can’t leave Dahlia’s and Gladioli in the ground.
