Shrubs like hydrangeas flower from mid to late summer on the previous year's growth. Mophead and lacecap hydrangeas will bloom satisfactorily with little attention, but regular pruning encourages new, vigorous growth that can produce a better display.

What month do mophead hydrangeas bloom?

Each type of hydrangea has a different bloom time. For instance, mophead hydrangeas bloom from late spring to midsummer in the southernmost regions. The exception to this is the new re-blooming hydrangeas which may bloom the entire growing season.

What months do hydrangeas bloom?

The hydrangea blooming season depends upon the type and cultivar as well as your planting zone. Most new growth hydrangeas put on buds in early summer to bloom in the following spring, summer and early fall seasons. In hot climates, hydrangeas may stop blooming in the heat of summer, but will rebloom in the fall.
