Why Deadheading Reblooming Roses Like Knockout Matters: The Science of Flower Production

Roses bloom to set seed hips. If hips form, the plant thinks reproduction is done and stops flowering.

Deadheading (snapping/cutting spent blooms) tricks the rose into blooming again. Even "self-cleaning" roses like Knockout and Carefree Wonder benefit—removing the hip signal keeps the flower factory running.
