Care
Watering
Water regularly when first planted, then moderately once established. Agrimony tolerates summer drought well. During active growth, keep the soil moist without excess moisture. Reduce watering in winter.
Light exposure
Plant in full sun or partial shade for optimal flowering. Sunny exposure strengthens the fragrance of the foliage and stimulates flower production. It also tolerates slightly shaded locations without losing vigor.
Soil preparation
Prepare well-drained soil enriched with organic matter. Agrimony adapts to poor or chalky soils. Avoid chronic waterlogging which promotes rot. A compost application in spring is usually sufficient.
Pruning and maintenance
Prune lightly after flowering to encourage branching and maintain a compact shape. In late winter, remove dead or damaged stems at ground level. This plant tolerates pruning well and regenerates quickly.
Fertilization
A moderate application in spring is generally sufficient. Use a balanced organic fertilizer or well-decomposed compost. Avoid excess nitrogen which would favor foliage over flowering.
Diseases and pests
Agrimony is generally very resistant. Occasional monitoring for aphids in case of water stress. Mildew can appear in very humid and poorly ventilated conditions; prefer good air circulation.
Did you know?
Fragrant agrimony was highly valued in medieval European herbalism, particularly for preparing infusions. Its name comes from the Latin "agrimonia" and Greek "argumon", terms evoking reputed beneficial properties. Its leaves release a slight tart fragrance, hence its French epithet "odorante".
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.
