Daylilies are very easy to grow. Though their blooms only last one day, it’s possible for a healthy plant to flower for many weeks. But should you cut off old, spent blooms? The Answer is YES… There are two reasons to consider deadheading daylilies!
#1: Aesthetics: Daylily flowers last only one day, and after they fade they quickly turn to mush.
#2: And plant health: Daylilies spend a tremendous amount of energy on seed production. Seed production in turn takes away from root and shoot development and future flowering potential. From a plant health perspective, seed pods should be removed so that daylilies will produce more flowers next season.
