À propos black buckwheat [green manure]

Black buckwheat

This is a green manure that has been cultivated in Quebec for a long time. It is used to prepare, enrich, and sanitize the soil. It is very effective at clearing weeds from the soil. It thrives in sandy soils but grows well in clay. Since it does not tolerate frost, it is planted from early June to early September. Its beautiful white flowers attract a multitude of beneficial insects. This is why it is dug in when its flowering period ends.

We have sizes from 1/2 kg to 2 kg in the green fertilizer section.

Growing tips for green manures

Green manures are crops intended to be worked into the soil to increase fertility. Growing green manures has many benefits. Among other things, it allows you to prepare new land. Grown cyclically, green manures rest, enrich, and cleanse the soil. Established in the fall, they protect the soil from erosion and leaching and preserve its structure.
