Plant the young plants as deeply as possible, but leave the crown, i.e., where the stem meets the roots, above the earth. If you have a greenhouse or use a foil tunnel or fleece, you can even plant them out as early as April. All can be planted out in the bed from May to the end of June.

If you have sown your red cabbage as described above, then you will have vigorous young plants. As soon as the red cabbage seedlings have more than four leaves, they can be pricked out Planting red cabbage When to plant red cabbage? Temperatures should not fall below 0 ☌ for long periods in winter, and there should only be short periods of frost. This is only possible in mild regions without heavy frosts.
Once daytime temperatures of around 10 ☌ arrive in spring they will continue to grow and can be harvested from March to May. Sowing spring red cabbage: Sow bolt-resistant varieties in July – August and transplant to their final home in September – October. Subsequent sowings in April and May are also possible with these varieties-this way, late red cabbage can be harvested from October to December. Sowing autumn and winter red cabbage: Sow these late and very late, slow-growing red cabbage varieties between March and the beginning of April in a cold frame or a foil tunnel. Summer cabbage is ready for harvesting between July and September. From May onwards, the young plants can either be transplanted from the cold frame into the bed or the foil tunnel can be removed.
Suitable places for sowing are unheated cold frames or beds with foil tunnels. Sowing summer red cabbage: If you want to harvest summer cabbage varieties, sow the appropriate seeds in March or early April. Between May and June, the plants develop into heads that are ready for harvesting. Continue to grow the plants in a cold frame, greenhouse or in a bed covered by a foil tunnel as cabbage plants require a minimum of 15 ☌ to grow. After the first true leaves have developed, prick out the red cabbage seedlings and plant in nutrient-rich soil. Sowing late spring red cabbage: Early varieties of red cabbage can be sown from February to the beginning of March in heated greenhouses, heated cold frames or in a comparable, cool spot that is frost-free and about 15 ☌. Plus, it is sustainably produced and peat-free! For example, our Plantura Organic Herb and Seedling Compost is ideal for growing young plants due to its low nutrient content and loose structure. A low-nutrient growing compost is most suited as a planting substrate for red cabbage seedlings since it stimulates robust root growth, which is beneficial when transplanting later. They will then be transplanted later in the season to their final spacing of 30 – 45 cm apart. Sow red cabbage seeds evenly in the rows and cover with soil. Alternatively, when sowing directly into the bed, dig 1 cm deep rows leaving 15 cm space between the rows. The first step for growing red cabbage from seed starts with sowing the seeds in a cold frame or seed trays-spread the seeds evenly over the growing medium and cover with 1cm of soil prick out the seedlings and transplant into separate pots after germination. Planting red cabbage: here’s how it worksĭetermining when to sow red cabbage depends very much on the variety: a basic distinction can be made between summer (sown in early spring), autumn (sown in late spring) winter (sown in spring) and spring cabbages (sown in late summer).
