Has produced the finest celeriac here in our clay soil. The root grows large and smooth with its roots gathered well beneath it. It has a tall build with dark-green, upright tops. Mars is suitable for both early cultivation under glass or plastic sheets and for a large and very storable autumn crop. Its flesh is white and of the best quality. A portion contains about 200 seeds.

SowingThe celeriac needs a long season and must be pre-cultivated. As the seed wants light to germinate, you should sow the seeds shallowly (2 mm) already in February-March, 10-12 weeks before planting as planned. Keep the soil moist with a temperature of 18-22° C during germination, which takes 14-24 days. To shorten the germination-time put the seeds in lukewarm water for 24 hours, dry them and sow.
Give the seedlings a lot of light and lower the temperature after a few weeks. You will need to pot them on at least once because of the long time they spend developing. Temper them gradually without exposing them to too low temperatures. The risk of runners grows markedly if the temperature is below 13°C for a longish time. Temperature shocks can also cause flowering. Plant outside when the earth has warmed up and the risk of nightly frosts are over.
