A little extra care can make a big difference for any size flower arrangement or fresh flower bouquet. Most floral arrangements last 5-7 days or longer, depending on the flowers used and the care they receive.
Refresh the water every few days in a clean vase and give the stems a trim to promote water absorption. If the vessel contains floral foam, make sure to keep the water filled above the foam. Make sure no foliage falls below the water line to prohibit bacteria from forming. Keep the arrangement in a cool place as well as out of direct sunlight and direct air flow to prevent dehydration.
