Cut the stems about an inch from the bottom. Fill a tall vase with cold tap water. Place the lilies in the vase. Recut the stems and add fresh water every few days. As the buds open, you may want to remove the pollen because it could stain the petals or your clothes. If pollen stains occur on blooms, remove with a chenille (fuzzy) pipe cleaner. If pollen stains occur on clothing or material, remove with sticky tape (DO NOT APPLY WATER).
