The Brussels sprout originated in Belgium. This surprising hybrid has a sturdy stem, up to one metre long, with large leaves with wavy edges. Small, round apples with tightly packed leaves are inserted into the leaf axils and grow from autumn until the end of winter. Brussels sprouts are a biennial plant, a winter vegetable that can be sautéed, boiled, baked or grated into salads. The best known varieties are: de Rosny (traditional variety), demi-nain de la Halle (old variety), Prince Marvel (early variety) and Sanda (excellent taste).
Brussels sprouts are easy to grow in the vegetable garden.
Brussels sprouts are sown under cover at the end of winter or in the spring so that they can be planted in the ground according to a schedule that runs from March to August. Emergence occurs between 8 and 10 days after sowing. When the plants have 2 or 3 leaves, they must be thinned to 8 or 10 cm. They are planted in the garden when the plants have 6 to 8 leaves. Brussels sprouts adapt to cold temperatures. It likes old manures and does not appreciate nitrogenous soils.
The care required by this vegetable is minimal: regular hoeing to avoid weeds and maintain freshness, watering if necessary and staking to keep the plants upright. Brussels sprouts reach maturity between 6 and 12 months after sowing.
