Description
Mizuna cabbage or Japanese mustard (Brassica rapa japonica) is a tasty leaf vegetable belonging to the large Brassicaceae family. It is closely related to turnips and Chinese cabbage. It forms loose heads of narrow, serrated green leaves. Mizuna has a mild peppery flavour and is often eaten raw as baby salad greens or lightly cooked in a stir-fry. This biennial plant, grown as an annual, is remarkably healthy thanks to its high vitamin A, K and C content. It is also a good source of fibre and minerals such as calcium and potassium.
Mizuna is very easy to grow, being both vigorous and cold-resistant. Ideal for winter crops! It requires deep, rich soil, regular watering and plenty of sun.
Harvest: Harvest the leaves as and when required by cutting them off at ground level.
Storage: Mizuna will keep for several days in the refrigerator.
Good to know: Mulching with grass clippings or dead leaves will help keep the soil moist whilst limiting weed growth.
Even if the vegetable garden is first and foremost a place for growing great quality veg, it’s always a good idea to leave a bit of room for flowers. Growing flowers alongside your vegetable plants will make your general gardening experience more enjoyable and is a great way to attract pollinators and repel garden pests! Flowers such as gaillardia, marigolds, zinnias, cosmos or nasturtiums can be sown in and around the rows of vegetables. Herbs such as dill can be very useful also. Bear in mind that some companion plants self-seed easily and can be a bit invasive (borage, chives, lemon balm etc.)
NB. Organic seeds (in French "AB" for "Agriculture Biologique") are produced from plants that aren't treated with phytosanitary products (insecticides, weed killers). The seeds do not undergo post-harvest treatment. They carry the AB label and are approved by Ecocert, an independent structure.

Planting and care
Sowing:
The Mizuna Cabbage has a germination temperature of around 14°C and takes about 14 days.
Sowing period: indoors from February to May or outdoors from April to August
Harvest period: from July to September
You can either sow the seeds directly in the ground or prepare seedlings that will later be planted in their final position in the garden.
Preparing seedlings: Indoors or in a nursery in the garden for the rest of the year (according to the recommended sowing period), sow the seeds at a depth of 1 to 2 cm in a good seed compost or fine soil. Cover lightly with compost and remember to keep the substrate moist but not waterlogged.
When the young plants appear strong enough to handle, transplant them into pots if necessary before planting them in the garden, when there is no longer any risk of frost. During planting, respect the recommended spacing for direct sowing.
Direct sowing: In properly amended and finely worked soil, make furrows about one or two centimeters deep, spaced 20 centimeters apart. Sow the seeds and cover them with a thin layer of fine soil. When the seedlings are well developed, thin them out, leaving one plant every 20 centimeters.
Cultivation:
The Mizuna Cabbage is grown in full sun. It is a demanding vegetable that requires well-rotted, nitrogen-rich and potassium-rich soil. It is advisable to apply a generous amount of mature compost (about 3/4 kg per m2), by scratching it to a depth of 5 cm, preferably in autumn, after thoroughly loosening the soil as for any vegetable crop. It is not very tolerant of soil pH, which should be between 5.6 and 6.5. In acidic soil, it will be necessary to gradually raise this pH by adding calcium in the form of Dolomite or Lime.
Beware of pests such as Cabbage White Butterfly or Flea Beetles and consider installing insect netting.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
