Description
Medicago sativa, also known as alfalfa, is a perennial legume that is used as a forage plant or green manure for several years on uncultivated land. It can fix atmospheric nitrogen in its roots. This green manure loosens soil with its deep roots, limits weed growth, and combats soil leaching or rain compaction. Sow from March to September. It can remain in place for 4 to 5 years.
Alfalfa belongs to the Fabaceae family. It is an herbaceous plant, 30 to 70cm (12 to 28in) tall, with leaves consisting of 3 leaflets. Its clusters of violet flowers appear in July. It is distinguished by its deep roots, which help to loosen soil. Alfalfa is resistant to cold and drought. It prefers soils with a neutral pH or a tendency towards limestone.
Widely used in organically cultivated gardens, green manures have many advantages. They nourish and improve soil by providing various nutrients and stimulating the soil's microbial life. Their roots will loosen, aerate, and break up soil. In addition, the presence of a vegetative cover protects the soil from leaching (nutrient loss in sandy soil), rain compaction (crusting in loamy soil), and erosion (caused by runoff in steep terrain during heavy rain). This vegetative cover also helps to limit weed growth. Finally, green manures are often attractive to pollinators.
Green manures are sown on uncultivated plots or intercalary plots, between rows of vegetables. They are either naturally destroyed by frost or cut before seed formation. Once destroyed, they can be left in place as mulch, be crushed and incorporated into the top layers of the soil, or be collected and added to compost.

Planting and care
Sow the seeds from March to September. Alfalfa prefers soils with a neutral pH or a tendency towards limestone.
If your soil is compact, loosen it to help the long roots to establish. Similarly, remove as many unwanted weeds as possible before sowing to ensure good germination.
Sow by broadcasting. Cover the seeds with soil using a rake. Firm the soil with the back of the rake and water lightly.
Alfalfa does not require any particular maintenance during cultivation or watering.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
