Heritage cabbage collections, from kohlrabi to broccoli, sow from March to June.

The organic cabbage seed box, offered in 6 or 12 varieties, contains one variety per packet, from Wiener Violetter kohlrabi to Brussels sprouts. Sow seedlings from March to June in a nursery bed, with germination in 6 to 9 days at 15 to 20 °C. Harvests run from summer to winter.

The word "cabbage" covers a wide range of very different vegetables on the plate. This set of 6 varieties brings together Wiener Violetter kohlrabi, Ramoso Calabrese broccoli, Snow Ball X cauliflower, Tête Noire 3 red cabbage, a white headed cabbage, and Brussels sprouts, sown in spring for harvests that run from summer through to winter.

🥦 Six vegetables, a single species

All these brassicas come from the same wild plant, Brassica oleracea, and selection has simply developed a different organ in each one, the one you harvest. Kohlrabi forms a tender bulb above the soil and is harvested in 8 weeks, which makes it the fastest of the family. Broccoli and cauliflower are harvested at the flower head, before the flowers open, and need more careful management, since a bolted head is lost. Headed cabbages, white or red, wrap their leaves into a dense head and are cut in one go in autumn. Brussels sprouts, for their part, occupy the ground from late spring until winter, and produce their first sprouts after the frosts.

A net against cabbage white butterflies from planting

The cabbage white butterfly and the flea beetle are the two main pests of brassicas. The cabbage white lays its eggs on the underside of the leaves and its caterpillars devour everything down to the veins; the flea beetle riddles young plants with hundreds of holes. A fine-mesh insect net put in place at planting deals with both at once. Plan for it from the sowing stage, so that you have it to hand on planting day.

Growing seedlings in trays frees up the bed

A winter cabbage occupies its spot in the garden for 6 months, yet its first 6 weeks need only a tray. By sowing in a 24-cell tray, you keep the bed free for a lettuce or a radish in the meantime, and you then plant out well-formed plugs that establish without any check to growth.

The transplanting itself calls for a precise technique. You lift the plant at the 4 true leaf stage and bury it up to its first leaves, deeper than it was in its pot: the stem then produces roots along the buried part and the plant withstands wind far better, which matters for a Brussels sprout that reaches 80 cm in height. A generous watering on the day of planting, followed by mulching, completes the job.

📅 From seedling to planting out

For brassicas, most sowing is done in spring for an autumn and winter harvest. Winter cabbages are sown from March to May, transplanted 5 weeks later and harvested from October to February, with the cold even improving the flavour of Brussels sprouts and kale. Kohlrabi and broccoli, much quicker, are sown from March to July and cut 2 to 3 months later. Sow under 1 cm of soil and allow 6 to 9 days for germination in a grow medium at 15 to 20 °C. At planting, the spacing determines the size of the harvest, and it varies a great deal from one type of cabbage to another.

Kohlrabi

25 cm between plants; harvest when the head reaches 7 cm, beyond that the flesh becomes fibrous.

Broccoli

50 cm, and cut the central head before flowering to encourage lateral shoots.

Headed cabbage

50 to 70 cm depending on the variety; a cabbage planted too close together forms a smaller head.

Brussels sprout

60 cm, a support stake is recommended, and harvest the apples from the bottom upwards after the first frosts.

🏺 Seeds for several springs

Stored somewhere dry, cool and out of the light, cabbage seeds keep their germination capacity for 4 to 5 years, which gives you time to sow a whole box of 12 varieties over several springs. A germination test on a few seeds, before sowing an entire tray, tells you what a packet opened long ago is worth, and the article on germination failures details the other causes of poor emergence.

🌸 Crosses and seeds

If you would like to produce your own seed, bear in mind that most of these cabbages are biennial: they only flower in the spring of their second year, after overwintering in place. Their flowers are pollinated by insects, and all varieties of Brassica oleracea cross with one another, cauliflower and red cabbage included. So let only one variety flower at a time, setting aside several plants for it, then harvest the seed pods once they are dry, before they split open.

The cabbages in the set need space and a long season, which makes them best suited to the garden or a large grow bed. If you are looking for a cabbage for an aquaponic system or a small space, the Dwarf Pak Choy follows a different logic: this Asian species, Brassica rapa, can be cut 45 to 60 days after the seedling stage, thrives in a bed filled with clay pebbles and can be re-sown in succession all summer.
