Watering
Add approximately 500–1,000 ml of fresh, cool water according to the vase size, covering the lower stem ends without submerging any leaves. Check the water level and clarity daily; a finger test does not apply to cut flowers. Replace the water every day in summer or warm rooms and at least every two days in cooler conditions, rinsing the vase each time. Do not allow stagnant water or an overcrowded vase, as bacteria-rich water quickly damages the stems.
