An easy to grow Brassica which matures in as little as 12 weeks from sowing and resists bolting! Kohl rabi ‘Kossak’ produces large bulbs of up to 3kg which remain tender, without becoming woody. The pale green bulbs have a pleasant, mild flavour. Both the stems and the leaves can be enjoyed in stir fries and salads, making this a versatile ‘no waste’ vegetable. Height: 35cm (14). Spread:30cm (12").

Companion planting: Try growing Kohl rabi with Nasturtiums to draw cabbage white butterflies away from your crop, and mint to help deter flea beetles.

Sowing

Direct sow outdoors from March to August at 4 week intervals, into a well prepared seedbed on any fertile, light, well drained soil in full sun. Sow at a depth of 1cm (½") and distance of 30cm (12") between rows.

Prepare the soil in early spring by adding plenty of well rotted farmyard manure to the soil to improve its structure and fertility. Apply lime to acid soils to reduce the acidity and lessen the risk of clubroot.

Thin Kohl rabi seedlings when their first true leaves appear, to a distance of 15cm (6") apart. Cover seedlings with a protective netting or fleece to prevent attack from birds and insects.

More Info

Water regularly to keep the soil moist at all times. Adequate moisture is essential for the most succulent roots and to minimise woodiness, bitter flesh and bolting. Harvest the bulbs from July to October while they are still tender. The leaves may also be harvested and eaten steamed or sautéed.
