Care
Sunlight
White campion prefers full sun exposure for abundant flowering. A partially shaded location is acceptable but will reduce flower density. Place it in a well-ventilated spot to prevent fungal diseases.
Watering
Water regularly during growth and flowering, especially during dry periods. Once established, this plant tolerates drought well. Avoid water accumulation at the base which could promote root rot.
Soil Preparation
White campion adapts to most soils as long as they're well-draining. Enrich the soil with compost before planting. Slight alkalinity or neutral pH are ideal for its development.
Pruning and Maintenance
Deadhead spent flowers regularly to prolong blooming and encourage new flower production. Cut back the plant in late autumn or spring before growth resumes to maintain a compact shape.
Fertilizing
A balanced fertilizer application in spring is sufficient. Avoid excess nitrogen which would promote dense foliage at the expense of flowers. A low-nitrogen fertilizer for blooming is ideal in summer.
Disease Prevention
White campion is generally robust but may suffer from rust or powdery mildew in humid conditions. Ensure good air circulation and avoid overhead watering. Remove affected parts promptly if necessary.
Did you know?
White campion has been known since Antiquity and was once called a 'wayside companion' in Europe because it grows easily along roadsides. Its white, fragrant flowers open particularly in the evening, attracting nocturnal pollinating insects like moths.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
