Care
Exposure
Burnet saxifrage prefers a sunny to partially shaded location. It tolerates open and airy spots well, which are essential to limit fungal diseases. Avoid overly damp or persistently shaded areas.
Soil
This plant adapts to many soil types, including chalky and poor soils. It prefers well-drained soil that is rather dry to fresh. Soil too rich in organic matter is not necessary and may even reduce the concentration of active compounds.
Watering
Water moderately when planting to establish roots. Once established, the plant tolerates drought well and only needs regular watering during very hot periods. Avoid excess moisture which promotes rot.
Pruning and cutting
Prune lightly after flowering to encourage branching. The aerial parts naturally disappear in autumn. You can harvest the leaves and fruits in summer if the plant is well established, without exhausting the rootstock.
Fertilizer
Burnet saxifrage needs no special fertilizer on ordinary soil. Enrich the soil at planting with some well-decomposed compost if the ground is very poor. Avoid excessive nitrogen applications.
Diseases and pests
This is a robust plant, rarely susceptible to diseases. Excess moisture can promote root rot or leaf spots. Ensure good air circulation and adequate drainage. Pest attacks are rare.
Did you know?
Burnet saxifrage has been used since ancient times in herbal medicine, particularly in Germany and Central Europe, where its fruits and leaves long featured in recipes for traditional digestive tonics and syrups. The name 'saxifraga' means 'stone-breaker' in Latin, as it was once believed capable of dissolving kidney stones—an ancient belief that gave this humble wayside plant its poetic nickname.
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.
