Will Deadheading Hydrangeas Cause Them To Rebloom?

Deadheading is the process of snipping or pinching off the spent blooms of a plant, which can be beneficial for hydrangeas. It encourages plants to bloom more by focusing their energy on producing new flower heads, leading to an abundant and extended display of blooms. This is especially important for reblooming hydrangeas, such as White Wedding Hydrangea, which should be deadheaded right after they finish their spring or summer blooming cycle.

Deadheading is not a crucial task, and it will not damage the plant if not done properly. Instead, the plant’s energy will be directed towards producing new flower heads, leading to an abundant and extended display of blooms. However, deadheading hydrangeas will not make them bloom again, as they only bloom once.

Endless Summer® hydrangeas rebloom, so deadheading helps focus the hydrangeas’ energy on producing more blooms for you to enjoy throughout the growing season. If the blooms on your hydrangea shrubs are fading or turning brown, it is simply a sign that it’s time to remove the flowers. Deadheading will not encourage rebloom, even on reblooming or remontant forms, as new flowers on these types come from a different area.

If you deadhead too late, it may cause your hydrangea to forego blooming at all. New wood hydrangeas will form their flower buds on new growth, so it’s essential to be patient and wait for a delightful treat again the following year. Deadheading hydrangeas is not a crucial task, and it will not damage the plant if not done properly.
