Reviving Cut Hydrangeas

Prepare a fresh vase. The bacteria that grow in vases of cut flowers shorten the life of the cut hydrangeas. Add room-temperature water to within 2 inches of the top of the vase and mix in floral food. This product provides nutrients to help revive the wilted hydrangeas.

Cut the stems of the wilted hydrangeas. Creating a fresh cut will improve the water uptake for the hydrangea bloom. Cut the stems at a 45-degree angle, ideally under water. Cutting the stem under water protects the wilted hydrangea from more moisture loss. Use a sharp knife or sharpened shears. Do not use scissors or a dull implement, as these tools will crush the stem and damage the flower's ability to receive water and food.

Revive hydrangeas with the boiled water technique. According to Judith King, a member of the American Hydrangea Society and creator of HydrangeasHydrangeas.com, hydrangea blooms sometimes wilt quickly due to the sticky fluids in the stems; to revive hydrangeas, boil water, then put the hydrangea stems into the hot water for 30 seconds before putting them into fresh water.

Place the revived hydrangeas in a cool location. If they are for an outdoor event, keep them cool until it is time to put them out. If possible, keep them out of direct sunlight and away from heating vents.
