Suitable for fresh eating and for long-term storage.

Radishes are rich in ascorbic acid, folic acid and potassium.

They are a good source of vitamin B6, riboflavin, magnesium, copper and calcium.

One cup of sliced radishes provides approximately 20 calories.

Winter radishes (black, white and purple radish) are sown in summer and produce large, pungent roots that keep through the winter.

How to sow and grow Japanese Radish Agata

• Sowing method: direct
• Depth: 2 cm
• Spacing: 15–20 cm in the row, 30–40 cm between rows
• Germination: 4–7 days at 15–20 °C
• Position: sunny spot

Radishes grow best in cool, damp weather at 10 - 18 C. Plant outdoors in full sun as soon as the soil can be worked. Plant 1 seed every 3 cm, covering it lightly with soil. These plants get large, so do not sow thickly. When the plants have 3 leaves, thin to 5 cm apart, so that there are no weeds. High yields are obtained by supplying the plants with moisture continuously throughout the whole growing period. An early-maturing variety, 50-60 days are needed after sowing.

Sow in July–August; water regularly so the roots do not turn woody.

Harvest and use

Harvest before hard frosts and store in sand in a cool place.
