Niger is a fast-growing annual green manure of tropical origin that is becoming increasingly popular among both organic producers and discerning home gardeners. If you are looking for a cover crop that does not transmit local plant diseases, Niger (also known as Niger seed) is the best choice.
Why choose Niger for your garden or field? Unlike mustard or clover, Niger belongs to the Aster family (Asteraceae). This means you can safely use it in crop rotations featuring crucifers (cabbage, rapeseed) or legumes (peas, beans) without the risk of spreading clubroot or other shared pests.
Key Benefits:
-
Natural phosphorus fertilizer: Niger’s root system can make bound phosphorus in the soil available to subsequent plants. This saves money on additional fertilizers.
-
Excellent bee favorite: Late-summer blooming provides pollinators with essential nectar at a time when many other plants have already finished.
-
Drought tolerance: Thanks to its origin, the plant withstands even the hottest summer days, maintaining its lush biomass.
-
Improving soil structure: Rapid growth smothers weeds and leaves the soil rich in organic matter after being plowed in.
Instructions for use:
-
Sowing rate: Approx. 10–15 kg/ha for green manure (approx. 100–150 g / 100 m² for home gardens).
-
Sowing time: As it is a frost-sensitive plant, sow the seeds in late May or early June once the danger of night frost has passed. It is also an excellent follow-up crop after early potatoes or peas.
-
Plowing in: For the best fertilizing effect, plow or dig the plants into the soil during the early flowering stage.
