Circaea lutetiana subsp. quadrisulcata

Growth Characteristics

Circaea quadrisulcata is a perennial herbaceous plant that grows primarily in temperate and cold regions of the Northern Hemisphere. It prefers slightly shady and humid environments and grows to a height of approximately 30 to 60 cm. The leaves are oval-shaped with serrated margins.

Propagation Methods

This plant is mainly propagated by seeds and root division. For propagation by seeds, it is best to collect mature seeds in the autumn, refrigerate them, and sow them in early spring. For root division, separate and plant from moderately grown seedlings in spring or autumn.

Cultivation Methods
Circaea quadrisulcata thrives in semi-shaded environments with slight moisture. You should select well-draining soil and avoid excessive direct sunlight. While frequent watering is necessary to maintain constant humidity, care must be taken as poor drainage can lead to root rot.

Garden Uses

This plant is suitable as a ground cover or background plant in shaded or forest gardens. If the right conditions are provided, it can create a natural and soft atmosphere.

Important Pests and Control Methods
While Malteul-deul-ta is generally resistant to pests and diseases, root rot can occur due to excessive moisture. To prevent this, it is important to maintain well-drained soil and proper water management. Additionally, aphids and other insects may appear, which can be controlled using appropriate insecticides. For organic pest control, soapy water or vinegar can be used.

By managing it this way, you can grow Malteul-deul-ta Quadri-Sulcata in a healthy condition.
