Your floral arrangement can last an additional 5-7 days longer, depending on the type of flower and the care they receive. The Society of American Florists provides these tips for longer-lasting blooms:
Keep the vase filled (or floral foam soaked) with water containing flower food provided by your florist. To maintain the appearance of the arrangement, Florist will provide a package of flower food with each arrangement. Flower foods provide a combination of additives that balances and limits bacterial growth. It is important to follow the mixing directions on the food packet.
Most packets are to be mixed with either a pint or a quart of water. Flower foods should not be diluted with more water than is specified on the packet. If the water becomes cloudy, replace it entirely with new water. If possible, re-cut stems by removing one to two inches with a sharp knife. Be sure to use a sharp knife or clippers that will not crush the stems. Immediately place the stems into solution.
Keep flowers in a cool spot (65 to 72 degrees Fahrenheit), away from direct sunlight, heating or cooling vents, directly under ceiling fans, or near appliances. Heat from appliances or hot and cold drafts cause flowers to dehydrate.
Tips on how to Make your flowers last longer
Floral food helps to nourish the flowers and discourage bacteria from growing in the water. It is one of the best and easiest ways to extend the life of your flowers. It is very important to follow the directions on the package correctly. Improperly mixed floral food can do more harm than good.
Keep the floral foam soaked in water. The floral food added at the time of design by your florist will stay active.
WARNING: Regarding cats and lilies
According to the National Animal Poison Control Center, certain types of lilies can cause renal failure in cats that have ingested any part of the lily. We strongly suggest keeping lilies out of the reach of cats. For more information, contact your veterinarian or the Animal Poison Control Center (APCC) at www.aspca.org/apcc or call 888-426-4435. It is important to note that lilies do not pose a problem for other pets or humans.
