Care
Light and exposure
This alfalfa prefers full sun exposure, requiring a minimum of 6 to 8 hours of direct daily light. It thrives in airy locations and benefits from good air circulation. Plant it away from persistently shaded areas to encourage generous flowering.
Soil and planting
Prepare light, well-drained soil, ideally sandy or gravelly, with neutral to alkaline pH. Avoid heavy or overly wet soils that promote rot. Enrich the soil moderately at planting time, without excess nitrogen since legumes fix atmospheric nitrogen themselves.
Watering
Water regularly during the growth phase, particularly during dry periods. Once established, this plant tolerates drought well and requires only moderate watering. Be careful not to saturate the soil, which could cause root rot.
Fertilization
Apply balanced, light fertilizer in spring, or better yet, a modest compost application. Avoid nitrogen-rich fertilizers since this plant naturally produces its own nitrogen through its symbiotic relationship with soil bacteria.
Pruning and cutting
No strict pruning is required. You can pinch back the shoot tips in spring to encourage a bushier form. After flowering, lightly cut back the plant if it becomes too leggy.
Health and prevention
This plant is generally robust and rarely subject to disease. Watch for excessive moisture that could promote root rot. Good drainage and adequate aeration are sufficient to prevent most fungal problems.
Did you know?
Coastal alfalfa, Medicago littoralis, is a coastal legume that was long overlooked by gardeners, even though it was once grazed by livestock in Mediterranean zones. Its name "littoralis" reveals its love of the seaside and its remarkable ability to tolerate sea spray and saline soils—a rare and precious asset for exposed coastal gardens.
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.
