Harvest Tips
Cut flowers in early morning when stems are fully turgid. Make clean cuts at a 45-degree angle just above a leaf node. Remove lower leaves that would sit below the waterline in a vase. Place immediately in cool water with floral preservative. Carnations have exceptional vase life of 7-14 days; recut stems every 2-3 days and change water daily.
