Care
Light exposure
Shepherd's purse appreciates a sunny to partial shade exposure for optimal development. It tolerates bright and well-lit positions well. An airy location promotes its general health and limits humidity problems.
Soil and planting
Install it in well-drained soil, rather light and enriched with organic matter. It tolerates poor soils but prefers slightly fertile soil. Ensure adequate drainage to avoid water stagnation, particularly in winter.
Watering
Water moderately, keeping the soil moist but not waterlogged. During the growing period (spring-summer), increase frequency. Reduce watering in autumn and winter. Let the surface dry slightly between waterings.
Fertilizing and nutrition
A balanced fertilizer application in spring is generally sufficient. If the soil is poor, supplement with diluted organic fertilizer once a month during growth. Avoid excess nitrogen which would promote foliage at the expense of flowering.
Pruning and maintenance
Pinch young plants to encourage a branched habit and abundant flowering. Remove faded flowers regularly to extend the flowering period. Remove dead or diseased parts as soon as they appear.
Diseases and pests
Like other Brassicaceae, it can be affected by flea beetles and cabbage white butterflies. Watch for the appearance of aphids and treat promptly if needed. Ensure good air circulation to prevent fungal diseases.
Did you know?
Shepherd's purse derives its name from the great variability of its leaves: basal leaves are lobed and toothed, while stem leaves are smaller and linear. This botanical particularity makes it a remarkable plant for the study of leaf morphogenesis. In the past, passerages were used in traditional herbalism, particularly in Central Europe.
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.
