Red clover (country of origin Lithuania) is one of the best-known and most effective green manure crops for gardens and agricultural fields. This legume develops a strong, substantial root system that effectively loosens the ground and improves soil aeration. The greatest value of red clover lies in the rhizobia living on its roots, which fix atmospheric nitrogen and store it in the soil for subsequent crops. This makes it an indispensable choice for organic gardening and sustainable farming.
Because red clover quickly restores soil vitality, it is often sown as the very first crop on virgin land or depleted soil. It is also well-suited for growing with a nurse crop, as it tolerates shading well. A 1 kg package provides enough green manure for an average-sized home garden or a small field plot, establishing an ideal foundation for planting more demanding vegetables.
Usage and Cultivation Instructions:
-
Sowing time: Early spring through mid-July. Can be sown as a pure stand or undersown with cereals (as a nurse crop).
-
Location: Adapts well to most soil types. Good water permeability in the subsoil is critical, however – red clover does not tolerate standing water or persistent waterlogging.
-
Sowing depth: 1–2 cm.
-
Sowing rate: 1 kg of seeds is sufficient to cover approximately 500–700 m² (5–7 ares).
-
Harvesting / incorporation: For the best fertilizing effect, plow or dig the green mass into the soil at the beginning or peak of flowering. At this stage, the plant contains the highest amount of nitrogen, and the stems remain soft and decompose rapidly in the soil.
Tips and recommendations:
-
When establishing a new garden bed on weed-infested ground, sow the clover together with a fast-growing nurse crop (e.g., oats). This suppresses weeds, and after mowing the oats, the clover will take over and form an even carpet.
-
When digging in or plowing under the green mass, make sure that the plant material is not buried too deep (over 20 cm) into an oxygen-depleted layer, where it may rot instead of decomposing properly.
