White Hydrangea Blooms Turned Green - Knowledgebase Question

I bought a gorgeous hydrangea macrophylla with large white blossoms, and they quickly turned green. The plant itself still looks great though. How do I get the blooms back to white?

White flowers sometimes have a greenish tinge when they first open, but this generally disappears with maturity. Because your shrubs are so newly planted, they may also be struggling to become established while they're expending energy to bloom. The combination may have encouraged the premature failing of the blossoms. Hydrangeas bloom on last year's wood so cut back the stems that have finished flowering to promote the growth of new stems, which will develop new flower buds. Next season they should look spectacular!
