Flowers often are used for special events such as weddings, anniversaries and birthdays. Since they hold such special meaning, many people like to store them to help keep their memories fresh. For flowers to survive for a significant amount of time after being pulled from the ground, they must have wet, cool conditions. The easiest and most efficient way of providing this environment is to put them in a refrigerator.
Fill a flower vase or any type of container large enough to hold and support flowers half full with water.
Cut 1/4-inch off the bottom of the flower stems and immediately put them in the vase. If possible, cut them while they are submerged in water. If air touches the stems, it can clog the tiny pores that transport water to the flower, thus reducing the life of the flower.
Remove fruit from the refrigerator. Some fruits, especially apples, give off ethylene gas that speeds aging in flowers.
Place the flower vase in the refrigerator at a temperature between 35 and 40 degrees F.
Prolong the flowers' lifespan by leaving them in the refrigerator for at least six hours per day.
