Answer: Your lilies will look and perform best if you cut the flowering stalks down to below foliage level after all the flowers are spent. Deadheading simply means removing blooms as they fade and the stalks after all the buds have opened. As the season progresses you plants will send up new flowering stalks. It's important to cut or snap the flowers off the stalk as they begin to fade (before they develop a seed pod). Hope this sheds some light on the process.
