Alfalfa

Alfalfa (Medicago sativa) is a perennial legume valued both as a nutritious sprouting crop and as a field plant. As sprouts it produces mild, slightly nutty shoots rich in vitamins and minerals. It fixes nitrogen through root nodules, making it a natural soil improver. In Nordic gardens it is hardy and long-lived when established in a well-drained, sunny position.

Growing

For sprouts: rinse seeds and soak 6–8 hours in cool water, then drain and place in a sprouting jar or tray at room temperature (18–22 °C). Rinse twice daily. Sprouts are ready in 3–5 days when 3–4 cm long. For outdoor growing: sow seeds 0.5 cm deep once soil reaches 5 °C, spacing plants 15 cm apart in rows 30 cm apart. Tamp soil firmly to ensure good seed-to-soil contact. Seeds germinate in 3–5 days under warm conditions.

Care

For sprouts: rinse thoroughly twice daily to prevent mould; move jar to a bright spot once the first leaves appear to develop green chlorophyll. Outdoors: water young plants regularly until established; mature plants are drought-tolerant and need little supplemental irrigation once roots are deep. Avoid waterlogged soil. Do not apply high-nitrogen fertiliser — the plant fixes its own. Remove competing weeds during the first growing period.

Harvest

Harvest sprouts when they reach 3–4 cm and have developed small green leaves — typically 3–5 days after beginning germination. For outdoor plants, cut stems when one-tenth to one-quarter of the stand is in flower, leaving at least 5 cm of stubble to promote regrowth. Multiple cuts per season are possible.

In the kitchen

Use fresh sprouts raw in salads, sandwiches, wraps, and grain bowls where they add a light, nutty crunch. Stir into soups or stir-fries at the last moment to preserve texture. Young leafy shoots from outdoor plants can be used as a micro-green or salad addition.

Storing

Rinse harvested sprouts in cold water, drain thoroughly, and store in a sealed container in the refrigerator for up to 3–4 days. Do not store wet sprouts as they deteriorate quickly. Dried seed keeps its viability for 2–3 years in a cool, dry, dark place.
