Don’t throw away those last drops of soda! Pour about 1/4 cup into the water in a vase full of cut flowers. The sugar in the soda will make the blossoms last longer. Note: If you have a clear vase and want the water to remain clear, use a clear soda, like Sprite or 7-Up.
Just as it preserves your hairstyle, a spritz of hair spray can help your cut flowers look fresh longer. Stand a foot away from the bouquet and give them a quick spray, just on the undersides of the leaves and petals.
