Care
Sunlight
Plant Valerian in part shade or full sun, ideally with some afternoon shade in warm regions. It tolerates semi-shaded woodland areas well. Avoid overly hot and dry exposures in Mediterranean climates.
Watering
Keep the soil regularly moist during the growing season, particularly in spring and summer. Reduce watering in autumn and winter. Avoid waterlogging: the soil should be fresh and well-drained rather than soggy.
Soil Preparation
Enrich the soil with compost or potting soil at planting time. Valerian appreciates loose, slightly chalky soils. Improve drainage by adding gravel or coarse sand if the soil is too compact.
Feeding and Nutrition
An application of decomposed compost in spring is usually sufficient. You can supplement with a balanced fertilizer diluted at the start of the growing season. Avoid excess nitrogen, which promotes foliage at the expense of flowering.
Pruning and Cleanup
Deadhead spent flowers regularly to encourage prolonged blooming. In late autumn, cut back dry stems to ground level. Light cleanup of dead foliage in spring helps the plant get off to a strong start.
Diseases and Pests
Valerian is generally hardy. Watch for powdery mildew in humid conditions: ensure good air circulation and avoid prolonged leaf wetness. Root rot can occur if drainage is inadequate. Few pests significantly affect it.
Did you know?
Valerian has long been used in traditional herbal medicine for its calming properties; the root was particularly prized. In alpine mountain regions, it grows naturally in moist, rocky meadows, where its small pink or white flowers attract pollinators in the heart of summer.
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.
