The length of time that your floral arrangement will last depends on the type of flowers 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. Floral food helps to nourish the flowers and discourage bacteria from growing in the water. It is important to follow the mixing directions on the food packet. 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 1-2” from the bottom of the stem. Be sure to use a sharp knife or clippers that will not crush the stems. Immediately place the stems into floral food solution.

Keep flowers in a cool spot (65-72˚F), away from direct sunlight, heating or cooling vents, under ceiling fans, or near appliances. Heat from appliances or hot and cold drafts can cause flowers to dehydrate.

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.
