About deadheading:
To get the most from your flowers (doesn’t really matter if they’re asiatic lilies or daylilies) you have to deadhead them and remove dead parts of your plant. We need to take off bad parts of flowers as soon as they start to drop off, as we try to prevent lily from losing its energy. Deadheading protract life of flowers and enable them to produce more flowers to make your garden ever more beautiful !
