Description

Mibuna is a cold-resistant and productive Japanese green vegetable that produces chicory-like rosettes of narrow, dark green leaves with a distinctive peppery, mustard flavour. Perfect eaten raw as baby salad greens or lightly cooked in a stir-fry. Sow in February-March and September-October for regular harvests from April to November.

Mibuna is a biennial plantgrown as an annual. It 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.

Mibuna 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. If the plant is well established, it will continue putting out new leaves for several months.

Storage: Mibuna 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. Untreated seeds are produced from conventionally grown plants (that are often treated with phytosanitary products); however they do not undergo any post-harvest treatment. These seeds are approved for organic market gardening when organic seeds are not available.

Planting and care

Sowing:

Sowing period: in open ground in February/March and September/October

You can either sow the seeds directly in the ground or prepare seedlings that will then be planted in their final location in the garden.

Preparing seedlings: Under shelter or in a nursery in the garden for the rest of the year (depending on 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 be handled, transplant them into pots if necessary before planting them in the garden, when there is no longer any risk of frost. When planting, respect the recommended spacing for direct sowing.

Direct sowing: In properly amended and finely worked soil, create furrows with a depth of one or two centimeters, 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:

Asian 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 make a generous compost application (about 3/4 kg per m2), by scratching the soil to a depth of 5 cm, preferably in autumn, after loosening the soil as you would for any vegetable crop. It is not very tolerant of soil pH, which should be between 5.6 and 6.5. In acidic soil, you will need to gradually raise the pH by adding calcium in the form of Dolomite or Lime.

Beware of pests such as Cabbage White butterflies or Flea beetles and consider installing insect netting.
