Winter radish: a firm root after the summer harvest

Choose by flavour, shape and use

Ronde zwarte: Black, round winter radish with a white interior. Finely grate winter radish for a quark sandwich topping or mix it with apple in a raw salad. Cooking in soup makes gentler use of a larger root.

The white interior is crisp and peppery. The black outer skin mainly provides appearance and recognition; use a small raw tasting to assess the heat.

Choosing a suitable root crop

Winter radish and rettich describe different large radish types. Round black winter radish differs in form from long white rettich. Use your variety's sowing, spacing and storage data without copying properties between forms.

Make room underground

Feel whether the soil is loose enough below the top layer. A fine surface can hide a hard layer. Carefully relieve obstructive compaction when the soil is workable. Avoid fresh, coarse manure directly in a row where straight roots need to develop.

Sow in the final position

Sow winter radish in summer in its final position. Sowing too early can trigger flowering when you want a swollen root. Check the variety window and keep the germination zone evenly moist during summer drought.

The surface layer deserves attention

After sowing, keep the germination zone evenly moist. A hard crust and drying can hold back small plants. Water with a fine rose and do not walk over the row. A label helps you find the sowing position before recognisable leaves appear.

Give every young plant its own space

Thin young plants to the variety's wider spacing. Large roots need large leaves too. Keep weeds from filling the row, taking both space and water as roots need to fill.

Growing without large fluctuations

During dry periods, check moisture below the surface. Young plants and containers need more frequent watering checks than a well-rooted crop in a bed. Water according to need and let it soak down; a wet surface every day tells you little about the root zone.

Take time over the first one

Harvest once the root reaches a useful cultivar size, usually in autumn for winter types. Loosen the soil carefully. Lift a supply before severe winter weather if the growing position becomes too wet or cold for safe harvesting.

An unusual root tells you something

Bolting, small roots or growth cracks call for assessing timing, spacing and moisture. Root tunnels may indicate cabbage root fly. Remove clearly affected plants and follow cabbage rotation; a new seed packet does not remove a soil problem.

Start with a sound harvest

Use damaged roots first and store only sound ones, following guidance for the type and cultivar. Cool conditions and suitable humidity help limit drying, but check for deterioration. Storage advice for one winter cultivar is not a shelf-life promise for the whole species.
