Deadheading blooms from any perennial is a way to extend the flowering time of the plant. By removing the seedpod that is formed after the bloom, the plant will send out more flowers. Daylilies are no exception to this rule. Removing the spent flowers will extend the flowering season of this early spring perennial. The deadheaded flowers must be disposed of in a separate area such as the trash or a working compost bin. If the spent flowers are not removed from the area, they may attract unwanted pests or bacteria that can harm the flowering plant.
Select only spent flowers to be deadheaded from the daylily. These flowers will have already fully bloomed and will have the flower petals closed. Typically, daylilies will bloom from the lowest portion on the flower stem and work upward.
Wash the scissors under hot, soapy water. Rinse all soap residue from the cutting blades. Keep the scissors as clean as possible. This will aid in eliminating the possibility of spreading any disease or bacteria to the flowering main stem of the daylily.
Cut the old bloom from the stem using the scissors. Make the cut just at the mating point of the individual flower stem to the main growth stem. Leave approximately 1/8 inch to 1/4 inch of the stem base from the flower to the main stem. The wound will heal over in approximately one day.
Collect all deadhead blooms into the plastic bucket. Dispose of the blooms in the trash or a working compost bin. Keep all spent flowers well away from the daylily plants. The blooms will attract unwanted pests and may cause the flowering plants to be infected by decomposing bacteria or other diseases.
