I let all of my bulb foliage dry naturally then remove it.

Most spring bulbs of any kind should have their greens kept on. Without these, the next years blossoms will suffer. The leaves supply essential nutrients to the bulbs all summer until they die off naturally. A good instance is my crocus bulbs. I use a weed whacker to cut the grass in a small area. Around the edges, I used to have a lot of crocus bulbs that blossomed every year. Once in a while, the weed whacker will slice off the leaves after they have blossomed and the following year,. I don't see any flowers as the greens are very puny too. Same holds true with tulips and probably many other flowering bulbs. Two years ago, I tried to grow some saffron crocus and something chewed all the leaves off at groud level. Never saw a single green after that and there was no trace of any bulbs. This year, I an trying it again, but with a wire screen over the area to protect the greens. Without these, there is no life left in the bulbs, so they rot and die.

I know it looks ugly, but you should leave the leaves until you can actually pick it up. (It has separated from the stem.)
