Kalanchoe irrigation

Kalanchoe Adans.

Kalanchoe irrigation is based on ensuring cyclic drying of the substrate, eliminating the risk of tissue rot in this CAM-metabolism plant. Sub-irrigation is considered optimal as it prevents leaf wetting and the development of powdery mildew.

In the reference 8 varieties crop Kalanchoe, where this is mentioned in the description.

The physiological characteristics of Kalanchoe require moderate drying of the substrate between waterings, as excess moisture quickly triggers the development of root rot. When irrigating, water should be prevented from contacting the leaf blade, which prevents tissue deformation and minimizes the risk of powdery mildew spread.

In commercial production, drip or sub-irrigation systems are preferred. An important factor is water quality control: optimal pH values should be in the 5.7–6.2 range with strict monitoring of salt levels (EC).

Regulating irrigation intensity, including temporary suspension before transport, is used as a tool to control growth and maintain the commercial appearance of the plants. Unlike moisture-loving crops, Kalanchoe does not require constant high humidity; therefore, automated irrigation should be based on substrate moisture sensors.
