Cultivation advice


Sow 1-2 cm deep directly after the soil is ready or in green-houses and hot-beds. It develops fast (4-6 weeks). Sow the radish seeds every few weeks until August-September, even longer in green house.


1-3 cm between the plants and 10-30 cm between the rows.


Harvest often! Do not allow the radishes to grow to large and spongy. They will keep for about a week in the refrigerator. Do try to cook them as well, poached, fried, barbecued etc!


80-130 seeds/1g. One portion sows several meters, at least 50 g sows 100 m and 5-10g/m2  for a green-house or hotbed.
A portion contains about 300 seeds.
