Care
Exposure
White dittany prefers a sunny location, with at least 6 hours of direct sunlight daily for generous flowering. It tolerates partial shade, but blooming will be less abundant. Protect it from strong winds that could damage the stems.
Soil
This plant appreciates well-drained soil that is never waterlogged. Chalky or neutral soils suit it perfectly. Enrich the soil at planting time with compost or potting soil, then mulch lightly to maintain moisture.
Watering
Water regularly during the first summer after planting to establish roots well. Once rooted, white dittany is quite drought-tolerant and needs little watering under normal conditions. Avoid excess water, especially in winter.
Fertilizing
A well-decomposed compost application in early spring is generally sufficient. A balanced fertilizer slightly rich in potassium can be applied before flowering to support flower production.
Pruning
Prune lightly in late winter or early spring to maintain a compact shape and remove dead or poorly placed stems. Remove spent flowers after blooming to encourage more flowers to form. Avoid severe pruning as it slows growth.
Diseases and pests
White dittany is generally very resistant. Occasionally watch for powdery mildew in humid, stagnant conditions: improve air circulation and aerate the plant. No major pests reported under normal growing conditions.
Did you know?
White dittany owes its name to a remarkable property: on hot, dry days, its leaves and flowers produce such concentrated essential oil vapors that, it is said, a flame brought near them could ignite them without actually burning the plant itself. In the Middle Ages, this plant was venerated for its aromatic properties and was cultivated in monastic gardens.
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.
