Our reliablepurple and white heirloom kohlrabi is back. Now with organically grown seeds.They were introduced as variety in the 1860’s, and have been successfullycultivated to recent days, when modern expensive varieties and hybrids havetaken over the commercial cultivation.

SowingSow directly and gradually as soon as the soil has warmed up until the beginning of July. Do not allow the soil to dry out.
For early harvest: Sow thinly indoors or in a hotbed, about 1cm deep, 4-6 weeks before setting out the plants as planned! The seeds want warmth when germinating, preferably just above 20°C. After sprouting they should be in a light, cool and airy place to avoid lankiness and attacks by root-neck rot but not lower than 14°C for any length of time. Low temperature increases the risk of bolters a lot. Temper the plants gradually before setting them, when the risk of frost is just about over. Most kinds of cabbage can handle a night of light frost. Set out the seedlings a little deeper and tread down the soil preventing the cabbage flies laying their eggs.
SpacingHave 10-20 cm between the plants and 35-50 cm between the rows.
HarvestHarvest the kohlrabi when it is 5-8cm in diameter not larger! Inedible fibres grow just inside the peel if it is allowed to grow to large. Kohlrabi has a more "refined" taste than the swede, but is kept and used in the same way. Its keeping qualities are however a little worse. The smaller leaves of the kohlrabi are tasty too and can be eaten raw or cooked.
