Input (English): How to Keep Cut Calla Lilies Fresh?
Output (English): If you are cutting calla lilies yourself, give the plant a good watering the night before. Cut the flowers early in the morning. Use a clean sharp knife to remove flowers at the base of the stem. Make sure not to touch the flower heads to see if they are fresh. Get a deep vase and rinse very carefully afterwards to remove cleaning product residue. Use a sharp clean knife to cut the stem at a 45 degree angle at the right height so that It can be put into vase. Cut them underwater so the cut surface isn’t exposed to the air. Add flower feed to the vase water or, if you have none, a teaspoon of sugar and a drop or two of bleach for every two liters of water. Put the cut lilies to the vase.
