Care
Exposure
Bird's-foot Trefoil enjoys a full sun position for generous flowering. A sheltered spot away from wind is preferable, though the plant is naturally adapted to coastal environments. It tolerates sunny and warm locations very well.
Watering
Water moderately during growth, allowing the soil to dry between waterings. In summer, increase frequency slightly if temperatures are very high. Once established, the plant is relatively resistant to dry periods thanks to its deep roots.
Soil and drainage
Well-draining soil is essential to prevent root rot. Bird's-foot Trefoil tolerates poor, stony and even slightly salty soils, making it ideal for coastal gardens. Improve drainage with sand or gravel if your soil is too heavy.
Pruning and maintenance
Pinch out young plants to encourage branching and a compact shape. After flowering, you can cut back lightly to stimulate reflowering. Deadhead regularly to extend the flowering period.
Fertilizing
Undemanding, Bird's-foot Trefoil benefits from a moderate application of balanced fertilizer in spring. As a legume, it fixes atmospheric nitrogen and doesn't require generous feeding. Well-rotted compost applied at the start of the season is usually sufficient.
Pests and diseases
Naturally robust, Bird's-foot Trefoil is rarely affected by diseases. Watch for excessive moisture which could promote rot. In very humid conditions, good air circulation and optimal drainage reduce the risk of fungal problems.
Did you know?
Bird's-foot Trefoil draws its appeal from delicate golden-yellow flowers that bloom in compact clusters throughout summer. A companion plant of rocky coasts, it has long been used to stabilize coastal soils and slopes, benefiting from its natural ability to enrich soil with nitrogen through its symbiosis with soil bacteria.
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.
