Answer: In most cases you will "deadhead" spent flowers by cutting or pinching them off of flowering plants. This encourages the plant to develop more flowers. In the case of Asiatic lilies, the flowering stalk will develop several flowers and they will open from the lower part of the stem up to the top of the stem. Usually in succession but sometimes several will open all at once. When the petals begin to look old and wilted, just snap the flower off the flower stalk. Eventually there will be no more flowers opening but you will want to leave the flowering stalk on the plant. The stalk and the leaves will collect and transport energy to the bulb. When the bulb has enough stored energy the leaves and stalk will die down. The bulb will rest over the winter months and send up a new flowering stalk next spring. Hope this answers your question.
