Watering
Fill a clean vase with roughly 1–2 litres of fresh, cool water depending on its size, or enough to cover 8–12 cm of the stems. Check the level visually every day throughout the year, topping up as needed more often in warm conditions or when uptake is high; replace all the water every 1–2 days. A finger test is not suitable for cut flowers, so check the level, smell and clarity instead. Immerse only leaf-free stems: soil waterlogging does not apply, but leaves left under water encourage decay.
