Deadheading

Deadheading is the act of removing spent flowers or flowerheads for aesthetics, to prolong bloom for up to several weeks or endorse rebloom, or to put off seeding.Deadheading is beneficial to most herbaceous ornamental plants. It can get better overall look of a plant, give a fresh new look to an otherwise finished or even distracting item, and can promote vegetative and root increase rather than seed production and help retain the plant's healthy appearance.
