Most floral arrangements last 4-7 days or longer, depending on the flowers used and the care they receive. The Society of American Florists provides these tips for longer-lasting, more vibrant flowers:
For floral arrangements
- Keep the vase filled (or floral foam soaked) with water. Flower foods make flowers last longer but it is important to follow the mixing directions on the flower 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, or directly under ceiling fans. Most flowers will last longer under cool conditions.
- When selecting flowers, look for flowers with upright, firm petals and buds beginning to open. Yellow, spotted or drooping leaves are signs of age.
- When using woody stems and branches (such as quince, forsythia or lilac), cut the stem with sharp pruning shears. Place them in warm water containing fresh flower food to promote flower opening.
