Care
Watering
Keep the soil moist but not waterlogged. Water regularly during the growing season (spring-summer), particularly in dry periods. Reduce watering in winter.
Light
Prefer a position in partial shade or dappled shade. In cool climates, it also accepts non-scorching sun. Protect from too much direct heat in Mediterranean regions.
Soil and substrate
Prepare fertile soil rich in organic matter and well-drained. Valeriana excelsa appreciates moist soil but without water stagnation. Adding compost at planting time is beneficial.
Pruning
Cut back faded stems after flowering to encourage denser branching. In late winter or early spring, remove dead stems and clear out the plant.
Fertilizing
A balanced fertilizer application in spring is usually sufficient. Regularly enrich with decomposed compost to maintain soil fertility.
Diseases and pests
Valerian is rarely troubled by pests. Watch out for slugs and snails that enjoy young foliage. Avoid stagnant moisture to prevent rot and fungal diseases.
Did you know?
Valeriana excelsa, known as Great Valerian, has been recognized since antiquity for its calming properties. Its roots give off a characteristic odor that strongly attracts cats, just like common valerian, which made it a valued natural remedy in traditional European herbalism.
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.
