Deadheading Flowers: How to Encourage Repeat Blooms All Season

Deadheading—removing spent flowers—redirects plant energy from seed production to new blooms. This simple maintenance task extends flowering season, improves plant appearance, and often triggers a second flush of flowers.

Why Deadhead?

As flowers fade, plants channel energy into seed development. Removing spent blooms interrupts this cycle, prompting renewed flowering. Regular deadheading yields healthier, more floriferous plants and prevents unwanted self-seeding.

Plants that reliably rebloom after deadheading: bleeding heart, phlox, delphinium, lupine, sage, salvia, veronica, Shasta daisy, yarrow, coneflower, and many annuals.

Deadheading Techniques

Pinching/cutting individual stems: Remove flower stem just above the first set of healthy leaves below the spent bloom. Best for plants with distinct flower stalks.

Shearing: For massed small flowers (like creeping phlox or alyssum), shear back the top few inches after peak bloom. Check for hidden buds first—cut above any developing flower buds.

Timing and Frequency

Start early (late spring) when few blooms have faded. Spend a few minutes every 2-3 days—consistent light deadheading is easier than massive cleanup later. Stop in early fall to allow seed set for winter interest or self-sowing annuals.
