Dead-heading, the fourth type of pruning, is the act of removing spent flowers. This method is used for flowering plants such as Day Lilies that may have a different stalk than the main leaf of the plant. When the flower begins to die, instead of cutting off just the flower, you prune from the base of the stalk. This keeps the plant healthy and removes additional dead weight from the plant. Deadheading also lets the plant utilize the energy from the spent flower rather than continuing to nurse it’s last days.
