Successfully growing savoy cabbage

Headed cabbage and green cabbage are the two oldest cultivated forms of cabbage. This category is divided into two: smooth-headed cabbages, called head cabbages, and curly-headed cabbages, called Savoy cabbages. It is the latter that we are interested in here. They produce a tender head, less compact than that of white cabbage, and have wrinkled or corrugated leaves, which make them particularly resistant to cold. They can be grown almost year-round by alternating the different varieties available and adjusting their planting times. Thanks to their low climate requirements, they can be grown in all regions of France.

The History of Savoy Cabbage

Among the ancient Greeks and Romans, cabbage was already cultivated and recognized as the vegetable par excellence. There is no shortage of authors who cited it in their works: Theophrastus, Cato, Pliny the Elder, Ovid. It was also one of the rare vegetables of the Middle Ages. Recipes and quotations abound and testify to its strong presence on tables and stalls, up to sauerkraut, already mentioned in 1325. After Antiquity and the Middle Ages, the Renaissance also made a big deal of it. It is only recently, in Europe at least, that the consumption of cabbages has declined. They are probably competing with other out-of-season vegetables that have traveled a long way. Still, our predecessors appreciated their simple cultivation and especially their production period because by playing with the varieties, it is quite possible to harvest them 365 days a year. Savoy cabbage is one of the oldest cultivated cabbages, along with head cabbage.

Etymology

Savoy cabbage is named after the main city in the Italian region where it originates: Lombardy.

Taste

Savoy cabbage has a distinctive cabbage flavor, quite pronounced and flavorful. It pairs perfectly with winter dishes such as stews, casseroles, and casseroles.

Nutritional values

The nutritional value of cabbage is relative, since, like many vegetables, it contains mainly water. However, it is rich in vitamin C and the sulfur derivatives it contains have antimicrobial properties.

Anecdotes

The Romans, whose pharmacopoeia was very poor, saw cabbage as a universal remedy. Perhaps this was linked to the characteristic smell of its cooking? According to them, it had many virtues: curing melancholy, rheumatism, and even tumors.

Main subspecies and varieties

  • Climate-related risks / frost resistance : Savoy cabbage is hardy and survives temperatures down to -15°C. However, if it gets too cold, it will quickly go to seed. It is therefore advisable to protect it in regions with harsh winters.
  • Synonyms and other names : Savoy cabbage, pancalier cabbage, blistered cabbage, green cabbage.

How to successfully sow?

  • Sowing period : From January to June.
  • Sowing type : Sow in rows.
  • Germination temperature : 20 °C.
  • Need for cold proofing : Cold proofing allows for faster rising, but is not essential.
  • Soaking : Soaking allows for a more even and faster rise, but is not essential.
  • Distancing :
    • In the row: 50 cm on the row.
    • Between rows: 50 cm between rows.
  • Sowing depth : 1 cm deep.
  • Rising time : 6 to 10 days.
  • Thinning : Thin out 5 cm after the first leaves appear.
  • Places and conditions :
    • Under cover : Sow under cover from January to April.
    • Open ground / without protection : Sow from March to June in a nursery at 4 cm in all directions.

Crop maintenance and care

  • Soil preparation : Loosen the soil well before planting or sowing in place.
  • Transplanting : After sowing under cover, transplant a first time in a nursery when the plants have 3 to 4 leaves at 10 cm, then a second time in open ground when the plants have 6 to 8 leaves at 80 cm in all directions. After sowing in a nursery, transplant only once.
  • Watering :
    • Frequency: Very regular watering.
    • Quantity: Abundant watering without excess .
    • Period: Throughout the cultivation but more particularly at planting.
  • Tools : Watering can and hoe or hoe.
  • Weeding : Regular weeding is recommended throughout the growth of Savoy cabbage.
  • Hoeing / weeding / earthing up / mulching : Savoy cabbages need to be earthed up during cultivation. The soil brought back to the base throughout the season improves their anchorage in the soil and allows for better root development. Once this work is done, they can be mulched to limit watering.
  • Winter protection : To prevent the Savoy cabbage from going to seed too quickly due to the winter cold, it is advisable to install winter protection such as thick mulch or a winter fleece.
  • Harvest period : From September to March.
  • Part of the plant : The head of the Savoy cabbage is eaten.
  • Stadium : To determine if the cabbages are ready to harvest, press the top of the head with your fingertips. You should feel resistance.
  • Average yield : You can expect around 500 grams to 2 kg per apple, and one apple per plant.

Cultivation techniques

Crop rotation

It is recommended not to replant vegetable cabbages or green manures from the same family such as radishes, turnips, arugula, mustard, or rapeseed in the same place for 5 or 6 years. This avoids attracting pests specific to the Savoy cabbage family and avoids maintaining the presence of parasitic fungi in the soil. In addition, Savoy cabbage is nitrogen-hungry, so it should be planted if possible after a soil-improving plant, such as broad beans, peas, beans, clover, or alfalfa. After the cabbages, root vegetables can be sown, which will draw nutrients from deeper down.

Companion plants

Some aromatic plants (with a strong scent) can mask the smell of cabbages and thus deceive pests that are aware of their scent. For example, you can surround cabbages with lemon balm, sage, rosemary, coriander, dill, and even marigolds.

Conservation and storage

Method: Harvest apples as needed and store in a cool place.
Duration: Apples can be stored for 1 to 2 weeks in a cool place.

Uses of Savoy cabbage

Culinary: Savoy cabbage can be enjoyed raw in salads, cooked as a side dish, or as a main dish. Pan-fried, steamed, or baked, it can be prepared in many different ways. Here are some recipe examples: cabbage stew, cabbage pasta bake, stuffed cabbage, winter savoy cabbage pie, cod with savoy cabbage.

Diseases and pests of Savoy cabbage

Diseases

The pests

Savoy cabbage is susceptible to powdery mildew, a fungus identifiable by its white felting on the upper surface of the leaves. A well-fed and properly spaced crop will recover without special treatment. Downy mildew is the main disease of cabbages, occurring in cold, wet weather, especially on young plants. A spray of Bordeaux mixture may be enough to contain the disease.


Sowing them in summer is always a risk, as flea beetles (garden fleas) can feast on them. The inevitable forcing fleece or insect netting is then required. Aphid damage can also be a problem. Most often, their natural predators, which live in our gardens, limit the abundance during the season. One or two applications of black soap are often effective. When the quantities grown are not large, simple manual collection is sufficient. Slugs must also be monitored throughout the growing season. To get rid of them, you can spread a band of wood ash or sow an anti-slug mixture. You can also install a slug wall or use crop auxiliaries. Cabbage root maggots, the imported cabbage white butterfly, and cutworms can also invade this crop. Versatile solutions exist to get rid of them, such as an insect repellent veil or spraying tansy extract, which can get rid of all three. Pheromone trapping can also be useful for both white butterflies and cutworms.
