In the late summer we hear our customers asking this: “Why are my hydrangea flowers turning brown?” and then “Should I cut off the brown hydrangea flowers?” Since there are many types of hydrangeas, the answer to why they are browning and what to do about it isn’t necessarily thte same for all plants. Here are some reasons that various hydrangeas turn brown quickly, along with some photos of standard dried flowers.
1. The main reason that mophead hydrangea flowers such as Endless Summer and Nikko Blue turn brown is hot mid-day to afternoon sun. If mophead varieties are planted in full sun, or where they get hot sun during the noon hour, they will brown quickly. But if those plants are placed where the direct sun is in the early morning or late-afternoon and evening the flowers will last into the fall.

2. Lacecap hydrangeas also brown quickly if planted in full or mid-day sun. Although some lacecaps last longer than others, and a few such as Twist n’ Shout put out some new flowers later in the fall, in general lacecaps tend to go by faster than other hydrangea varieties. So plant these in early morning or evening sun and enjoy them while they last.
3. The white flowering Hydrangea paniculata varieties are the best able to grow and remain attractive in full sun. Varieties such as ‘Grandiflora,’ ‘Limelight’ and ‘Pinky Winky’ will turn pink as they age, but the flowers won’t brown out as long as they are well watered through hot weather.

4. All hydrangeas will turn brown if they wilt too many times in hot weather. Water these shrubs deeply every few days in the heat of the summer (note that hand watering isn’t deep enough) and mulch around plants to hold moisture in the soil longer.
5. When all hydrangeas are splashed with water on a daily basis, however, this alone can cause browning. Avoid daily irrigation and when watering try not to get the leaves and flowers wet as this promotes leaf-spot fungus that will brown both leaves and flowers.
6. What to do if your hydrangeas have brown flowers? Clip those toasted blooms off, snipping just under the browned flower. Removing browned petals improves the look of the plant and for re-blooming varieties helps to promote the production of more flowers.
