Cyclamen persicum, the classic indoor cyclamen, is one of the most popular winter bloomers. Although it is considered somewhat delicate, those who understand its needs can keep it healthy and thriving. Proper watering is especially important. myHOMEBOOK plant expert Franka Kruse-Gering explains why correct watering is crucial and what to keep in mind.
Why Proper Watering is Important for Cyclamen
The indoor cyclamen originally comes from the winter-moist, mild regions of the eastern Mediterranean, such as parts of Turkey, Syria, Israel, Lebanon, and Greece. There, it grows in open forests, shrubs, and shaded rocky areas. The soils in these locations are humus-rich, loose, and well-drained. During winter growth, the soil remains slightly moist, but waterlogging practically never occurs.
Characteristic is the flat tuber, which partially protrudes from the soil. This tuber stores nutrients and moisture but is extremely sensitive to prolonged wetness. If kept too moist, it lacks oxygen, and rot can quickly spread. At the same time, the soil must not dry out completely, as the fine roots of the cyclamen are sensitive to drought stress. This unique combination of moisture needs and sensitivity to wetness explains why Cyclamen persicum must be watered so carefully.
What to Consider When Watering Cyclamen
Before properly caring for a cyclamen, it is worth taking a closer look at its water-related needs. Cyclamen persicum is sensitive to how and when it is watered, making a basic understanding of its natural behavior particularly important.
Don’t Miss the Timing
Watering should only occur when the top layer of soil appears dry. In winter, when the cyclamen blooms, it needs more water than in summer, when it is in its resting phase. The best way to gauge this is by the weight of the pot. If the pot is light, it’s time to water. The finger test can also help determine the right time to water the cyclamen.

Cyclamen Can Only Handle One Direction
The safest way is to water the cyclamen from below by placing the pot in a saucer with water for about ten to fifteen minutes, allowing the soil to soak evenly. Any excess water should always be removed afterward. If watering from above, ensure that neither the tuber nor the leaf axils get wet. During the resting period in summer, water very sparingly.

Only the Best Water is Good Enough
For Cyclamen persicum, low-lime, room-temperature water is best. Rainwater is very suitable because it is less limey. Cold water should be avoided, as it stresses the plant and can lead to leaf loss.
How to Recognize Watering Mistakes
Yellow or glassy leaves usually indicate too much water. If the leaves become limp or curl, this is more a sign of dryness. A musty, rotten smell from the pot clearly indicates the onset of tuber or root rot.
