Brussels Sprouts Groninger

What Brussels Sprouts Groninger is

Brussels Sprouts Groninger (Brassica oleracea var. gemmifera) is an annual vegetable of the Cabbage family (Brassicaceae). Groningen is an easy-to-grow variety with steady production.

The sprouts form a firm head and keep a delicate flavour even in changeable weather.

This Brussels sprout variety can withstand light frost and will improve its flavour in the cold weather.

They are tender, crisp and of excellent flavour. Brussels sprouts are high in vitamins, mineral salts, carotene and crude protein.

Brussels sprouts produce dozens of mini cabbages along the stem and taste best after the first frosts, when they become sweeter.

When to sow Brussels Sprouts Groninger

Brussels Sprouts Groninger seeds are sown in March and April. Harvest in August – December. The months are a guide for a temperate climate — in warmer areas sow 1–2 weeks earlier, in cooler or upland areas, later.

How to sow and grow Brussels Sprouts Groninger

• Sowing method: seedlings
• Depth: 1 cm
• Spacing: 60 cm
• Germination: 5–10 days at 15–20 °C
• Position: sunny spot

Sow March-April for harvesting throughout the winter. Sow in a greenhouse or in the garden in beds, then transplant later. Keep the soil moist. If necessary, thin out the weakest plants to leave only one plant every 15 cm. When your cabbages have 5-6 leaves, plant them in the ground 80 x 60 cm apart. Brussels sprouts grow for a long time, so you can scatter radish or lettuce seedlings between them, which will be harvested earlier.

Plant the seedlings in May–June in firm, fertilised soil. Earth up the stems for stability.

Harvest and use

Pick the sprouts from the bottom up when they are firm and 2–4 cm in diameter — from October into winter.
