Care
Watering
Shepherd's purse prefers moderately moist soil without excess water. In natural conditions, spring and autumn waterings are sufficient; in summer, water lightly if the soil dries out on the surface. Avoid stagnant water which promotes fungal diseases.
Light exposure
This plant thrives in sun or partial shade. It tolerates sunny areas well and flowers abundantly with at least 4-5 hours of direct light. It can survive in partial shade but with less vigorous flowering.
Soil
Well-drained, light soil is ideal. Shepherd's purse tolerates poor, rocky or silty soils. It is not bothered by moderate acidity and adapts to infertile terrain where other plants struggle.
Pruning and maintenance
Pinch off the tips at the young stage to encourage branching. After the first flowering, you can cut back faded stems to stimulate new blooms. At the end of the season, leave some flowers to go to seed for natural reseeding.
Fertilizing
This plant is undemanding in nutrients. An application of balanced fertilizer in spring is more than sufficient. Avoid excess nitrogen which would encourage foliage at the expense of flowering.
Diseases and pests
Shepherd's purse is generally hardy. Watch for root rot if soil is too wet, and aphids which can colonize young shoots. Good drainage and adequate air circulation prevent most problems.
Did you know?
Shepherd's purse owes its common name to the characteristic shape of its siliques (flat, heart-shaped fruits) which resemble the small leather pouches that shepherds once carried. This hardy plant has conquered all continents and now ranks among the world's most widespread weeds, while also boasting a long history of traditional use in herbal medicine.
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.
