How to prune red spider lily

Remove spent flower stalks immediately after bloom (autumn); leave foliage until it yellows in late spring. Snap or cut the hollow flower stalk at ground level once all blooms have finished. Allow the green strap leaves to persist through winter and die back on their own without cutting.

Let the foliage die back naturally in late spring.
