Want to make your hydrangeas really last? Dry your blooms and they'll keep for several years.
Editor's tip for drying hydrangeas: If using Method A or B, start with older flowers with petals that feel slightly papery.
A. In the Vase: Once you've created your centerpiece, let water evaporate from the vase, and hydrangeas will dry by themselves.
B. Upside Down: Secure small bunches of blooms with string, and hang them upside down in a cool, dark place for several weeks until dry.
C. On the Plant: Let the flowers dry on their own, and then cut them off. This occurs naturally in late July, August, and September.
D. Last Call: In late fall, cut brown blooms and lightly coat with a florist spray paint, such as Design Master, to create colorful blooms.
