What is the process of "deadheading" in gardening?

The process of "deadheading" in gardening refers specifically to removing spent flowers, which are blooms that have faded and are no longer vibrant. By cutting off these spent flowers, gardeners can encourage the plant to produce new blooms. This is because many flowering plants will direct their energy toward seed production once flowers die, and by removing the old flowers, the plant is prompted to create new ones instead. Deadheading can lead to a longer flowering season and overall healthier plants, enhancing the beauty of a garden.

The other choices relate to different aspects of plant care. Trimming the roots of plants is more about root management, which can affect growth and health but does not pertain to promoting blooms. Watering plants less frequently is a watering technique that can be dependent on various factors such as plant type and environmental conditions, and it does not specifically relate to flower production. Applying mulch to the garden bed serves purposes like retaining moisture and suppressing weeds but is not involved in the direct process of encouraging new blooms.
