Answer: If your bulbs are struggling you might want to reassess their planting site and the winter protection you provide. Lily bulbs are quite hardy, but if the soil gets soggy and stays soggy all winter long the bulbs can suffocate. They also grow best in full sunshine and won't flower well if they don't get at least 8 hours of sun in the spring and summer months. I would cut the stalks down to ground level after they die back and then mulch over the bed with 4-5" of straw, pine boughs or shredded leaves to provide added protection this winter.
Best wishes with your bulbs!
