It may not be pretty, but it is neater while nature stores energy in the bulbs for next year's flowers. Loosely braid the leaves of drying bulbs for easy removal after they are dried.
When bulbs are finished blooming, you must keep the leaves in the ground until they turn brown, or else the bulbs will rot in the ground and you won't have any next year. So, instead of having a sloppy looking area where my bulbs were, I braided the leaves and turned them under to form large "O"s. It makes the area look nice and clean. Then, when they all turn brown, as in these pictures, they are ready to cut off. Happy Gardening!
