Deadheading removes spent flowers from plants so they will produce more blooms. When you remove the spent flowers, the plant will then produce another to aid in pollination, according to the University of Missouri Extension. Impatiens, an annual flower, are considered self-cleaning plants that do not require deadheading, according to the North Carolina State University Extension. However, impatiens can be deadheaded regularly to improve the plant's appearance.
Look through your impatiens to identify flowers in need of deadheading. Blooms that are wilted, faded, withered or damaged can be removed.
Pinch or pull off the flowers you have identified for deadheading. In the case of impatiens, you will not need any tools. A gentle tug or pull with your hand will be enough to remove the bloom from the plant.
Discard the deadheaded blooms with your yard waste or in a compost pile or bin.
Check your impatiens regularly throughout the growing season to see if additional blooms need to be deadheaded. Because they are self-cleaning, some of the plant's blooms should fall off throughout the season, but you can remove any unattractive or withering flowers as necessary to reshape the plant or keep it looking healthy.
