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 loose bunches or boxed flowers
- Keep your flowers in a cool place until you can get them in water.
- Fill a clean, deep vase with water.
- Remove leaves that will be below the waterline. Leaves in water will promote bacterial microbial growth that may limit water uptake by the flower.
- Re-cut stems by removing one to two inches with a sharp knife. Place the flowers in the vase you've prepared.
For floral arrangements
- Keep the vase filled (or floral foam soaked) with water.
- 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.
