When digging up tulip bulbs, to divide them:
(1) How do you avoid damaging the bulbs? I can't think of any way to
prevent goung some bulbs, except to have them in soil so friable (such
as Miracle Gro potting soil) that you could just lift them out and not
use a spade.
(2) When you have damaged a bulb, how much damage is "okay"? How
much can get lopped of, and the thing will probably grow next spring
anyway?

Thank you!
