More information

Also known as buckwheat, this annual plant, about 80 cm (32in) tall, is grown as a grain and as a green manure. It has the ability to smother adventive plants while protecting the soil from rain compaction. This green manure is distinguished by its cleaning and loosening power, and is particularly well-suited to heavy, acidic, compact soils and humid climates. It is sown from late May to early June at a rate of 5 to 10 grams per m2.

Description

The Buckwheat, also known as black wheat, is an annual plant about 80 cm (32in) tall, cultivated as a cereal and as green manure. It has the ability to smother adventive plants while protecting the soil from rain leaching. This green manure is distinguished by its cleansing and loosening power, and is particularly well-suited to heavy, acidic, compact soils and humid climates. It is sown from late May to early June at a rate of 5 to 10 grams per m2.

Widely used in permaculture, green manures have many benefits: they enrich and loosen the soil while preventing the establishment of adventive plants. They also have the advantage of forming a vegetative cover that protects clayey soils from rain compaction and sandy soils from leaching. They can be sown throughout the year, and can be incorporated by shallow digging or left in place as mulch before they go to seed.

Green manures can be used in vegetable gardens, but can also be used in poor, degraded, or compacted soils, for example before planting a hedge.

Gardener's tip: just like with vegetable crops, it is important to consider rotations for green manures: don't always sow the same ones in the same place!

White mustard: sowing, growing

Read article

Cultivated in France since the 14th century, white mustard, Sinapis alba, is an annual herbaceous plant that produces large pale yellow seeds used in the making of strong mustard. While their taste is bitter, it is less pungent than that of black or brown mustard. Grown as a green manure, Sinapis alba transforms into organic matter once destroyed by frost or by crushing, which naturally enriches the soil. White mustard covers the ground with its dense clumps, and leaves no room for weeds that it smothers. Its root system also allows water and air to penetrate the soil well, and effectively retains nitrates. This helps prevent pollution of groundwater. The roots of mustard have properties similar to garlic. They are thus a very effective and natural bactericide and nematicide. The plant therefore allows for the disinfection and sanitisation of the soil for a future vegetable garden. Mustard in general includes species from the genus Sinapis, as is the case with white mustard, and species from the genus Brassica. The Sinapis alba (white mustard) is the most suitable as a condiment, although Brassica nigra (black mustard) is also used for this purpose. Prepared mustard is generally made using a mixture of white mustard seeds and black mustard seeds, which are mixed with vinegar, must, or verjuice.

It is grown in open ground in sunny or semi-shaded conditions. Easy to grow, Sinapis alba requires very little maintenance, limited to light watering to keep the soil moist. Here are all our tips on this perfect green manure to improve the quality of your soils.
