Aglaonema irrigation

Aglaonema Schott.

The irrigation regime for Aglaonema requires a balance between its tropical moisture requirements and the plant's anatomical ability to store water, making it critically sensitive to overwatering.

In the reference 7 varieties crop Chinese Evergreen, where this is mentioned in the description.

Aglaonema possesses water-storage tissue, which allows the plant to tolerate short periods of substrate drying. However, excess moisture rapidly triggers root system decay; therefore, the top 5 cm of the soil must dry out completely before the next irrigation.

For normal crop development, it is necessary to use porous substrates with high aeration and ensure drainage of excess water from saucers. The use of moisture sensors indicates that the optimal substrate moisture level for Aglaonema is 50–75%.

During the winter period, water demand decreases, requiring adjustments to irrigation schedules. To prevent the accumulation of salts that negatively affect the roots, it is preferable to use filtered or rainwater. In commercial cultivation, the wick method is an effective irrigation technique.
