Care
Light exposure
Toothwort prefers partial shade or dappled shade, particularly in warm regions. It also tolerates sun in temperate climates if the soil remains moist. Avoid direct afternoon exposure in Mediterranean zones.
Soil
This plant thrives in soil rich in organic matter, moist to fresh and well-drained. It appreciates slightly acidic to neutral soils, typical of woodland or forest environments. Improve your soil with compost or peat before planting.
Watering
Water regularly to keep the soil moist, without waterlogging. During the growing period (spring-fall), weekly watering is generally sufficient. In dry summers, increase frequency to prevent the soil from drying out completely.
Fertilizing
Fertilizer is not essential if the soil is rich in organic matter. If growth seems slow, apply a balanced diluted fertilizer in spring. A good layer of compost or organic mulch in autumn will usually be enough.
Pruning and maintenance
No structural pruning is necessary. Simply remove dead or damaged leaves in late winter. After flowering, you can remove faded stems to encourage new leaf growth.
Diseases and pests
Toothwort is generally disease-resistant. Watch for slugs and snails that can damage young foliage, particularly in spring. Prolonged excess moisture can promote mold: ensure good drainage.
Did you know?
Toothwort gets its name from its characteristic compound leaves, usually divided into seven leaflets. This plant was once used in cooking for its slightly peppery leaves, similar to arugula, and remains a prized companion plant for wildflower gardeners in recreating natural forest understory environments.
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.
