How to Preserve Hydrangeas


Hydrangeas are beautiful, and it's possible to enjoy their beauty all year long by preserving hydrangea flowers. The preserved flowers can be used in bouquets, wreaths, centerpieces and other floral arrangements. Several methods are successful, including the use of alum, glycerin or silica gel. However, the simplest and easiest method to preserve hydrangeas is to dry them. The dried flower heads keep their color and shape for at least a year.

Step 1

Wait until the flowers are partially dry on the plant before cutting them. The petals should feel slightly papery instead of soft and moist. In most areas, hydrangea flowers for drying are ready to cut in late summer or fall.

Step 2

Cut the flowers in the morning, while temperatures are still cool but after the dew has dried.

Step 3

Strip all the leaves from the stems.

Step 4

Arrange the flowers in a vase, but don't add water. Use a flower frog in the bottom of the vase if needed to hold the stems in place.

Step 5

Keep the vase of hydrangeas out of direct sunlight as the flowers slowly finish drying.
