Sainfoin is a long-lived and hardy legume crop widely used as green manure, a honey plant, and in establishing perennial flower meadows. Its strong, deep-reaching root system effectively loosens subsoil layers and improves soil structure. Thanks to nodule bacteria on its roots, the plant fixes atmospheric nitrogen, leaving the soil organically enriched and reducing the need for additional fertilizers.
The crop produces abundant green mass, naturally helping to suppress weeds. Sainfoin is distinguished by excellent drought and disease resistance, thriving even during periods of low rainfall. For beekeepers, it is a highly valuable forage crop—plants with striking pink flowers achieve an average honey yield of 100–280 kg per hectare. The larger 1 kg package is an economical choice for covering larger areas or enriching wildflower meadow mixes. Note that this plant cannot tolerate acidic or peat soils.
Usage and Cultivation Instructions:
-
Sowing time: Direct sow outdoors starting in May once the soil has warmed sufficiently.
-
Location: Prefers full sun and neutral or slightly alkaline soil. Unsuitable for acidic, waterlogged, or peaty soils.
-
Application rate: When sown as a pure stand, 6–8 g / 1 m² (1 kg covers approx. 125–160 m²); in wildflower meadow mixes, 1–2 g / 1 m².
-
Sowing depth: 1–1.5 cm. Seeds require firm contact with the soil to germinate.
-
Height and blooming: Plants reach 90–120 cm in height and bloom in July. It is a perennial plant.
Tips and recommendations:
-
Because sainfoin does not tolerate acidic soil, it is recommended to neutralize excessively acidic ground (pH below 6.0) with garden lime or wood ash before sowing.
-
To promote biodiversity, combine sainfoin with other meadow species and grasses—its tall pink flower spikes add visual appeal while providing a long-lasting food source for pollinators.
