Get rid of wasted blossoms. This conserves energy and encourages next season's flowers. Cut dead blossoms above healthy leaves with clean, sharp pruning shears.
Hydrangeas may need pruning, depending on type. Prune mophead or lacecap hydrangeas (Hydrangea macrophylla) once the flowers fade.
Remove fallen leaves and blossoms from the plant base. Prevents disease and pests from overwintering in debris.
Give the plant nutrition from a balanced, slow-release fertilizer to recuperate from blooming and prepare for next year.
Mulch the plant's base to protect its roots from cold. Mulch suppresses weeds and retains soil moisture.
Assess your hydrangea's health. Check for disease and pests and treat. Healthy plants endure winter and spring well.
