Recovering Hydrangeas from Fertilizer Burn and Encouraging Rebloom

Signs of Over-Fertilization

Brown leaf edges, scorched flowers, and sudden bloom fade after heavy feeding.

Deadheading for Aesthetics and Rebloom

Remove spent flowers. On remontant types (Endless Summer, Forever & Ever), this stimulates a second flush.

Watering to Flush Excess Salts

Deep soak the root zone weekly to leach fertilizer salts.

Special Note on Endless Summer Hydrangeas

These bloom on old and new wood. Deadheading now promotes rebloom in a few weeks.
