Irrigation of Cape cowslip, Lachenalia

Lachenalia Jacq. f. ex Murr.

The irrigation regime for Lachenalia is strictly governed by its seasonal cycle: regular watering is required during the autumn-winter growing season, whereas watering is completely ceased during the summer dormancy period to prevent bulb rot.

In the reference 4 varieties crop Cape Cowslip, where this is mentioned in the description.

During the active growth phase, the plant requires moderate watering as the top layer of the substrate dries out. It is important to maintain consistent soil moisture while avoiding waterlogging, which triggers root system decay, and to reduce the volume of moisture specifically during the flowering period.

The watering technique requires caution: water should not come into contact with the leaves and flowers of the Lachenalia, as this causes the development of fungal infections. It is recommended to use bottom watering via a tray or to direct the water stream strictly to the base of the plant. To simulate natural conditions, increasing the air humidity around the plant is permissible.

During the summer dormancy period, the bulbs must remain completely dry. When growing in regions with summer rainfall, the use of containers becomes a mandatory condition, allowing for the protection of the plant from unwanted moisture and ensuring a complete dormancy cycle.
