Deadheading can help keep flowers blooming

The primary reason flowers exist is to produce more flowers.  In general, once a flower blooms and dies it forms seeds for the next generation. Deadheading, which is simply removing the spent flowers before they set seed, tricks the plant into believing it needs to keep blooming to produce seed for the next generation. Different types of flowers require different deadheading methods, but the simplest practice is to remove the spent blooms.

By deadheading spent flowers before
they start to set seed, keeps plants
blooming longer.
