Soil facts and preparation

Quick facts..

  • Soil Type Fertile and Well Drained
  • Ideal Ph range 6.5 to 7.5
  • Site Full Sun
Kohlrabi is a very hungry fast growing vegetable that will grow best in soil that is rich in organic matter. Add plenty of well rotted manure or fresh compost to the soil. Choose a site that is in full sun or occasional light shade.

For the best results, rake in a general purpose fertilizer approximately two weeks before your first Kohlrabi sowing

Sowing and planting

Quick facts..

  • Germination 4 to 7 days
  • Sow 10mm deep
  • Sow Spacing 150mm
  • Rows 300mm apart
Kohlrabi doesn't appreciate being transplanted, so it’s best to sow the seeds directly. Sow seeds thinly 1cm deep in rows 30cm apart and gradually thin the seedlings to a spacing of 15cm. When thinning be careful not to disturb the roots of neighboring seedlings. Note you can eat the seedlings so your thinnings need not go to waste.

Growing a bumper crop

Kohlrabi has a shallow roots system to it is important to keep the soil moist at all times, any period of drought may cause the roots to become woody and unpleasant to eat. Prevent competition for moisture and nutrients from weeds by carefully removing without damaging the roots.

Harvesting the fruits of your labour

Quick facts..

  • Yield 160g per plant
Harvest when the roots are approximately 5cm in diameter, somewhere slightly larger than a golf ball but not as big as a tennis ball. If left to grow any larger they will begin to loose their taste and develop a woody texture. Kohlrabi does not store at all well so lift as required and use immediately.

Remove the leaves from the root and peel, they can be eaten raw in salads when sliced finely or grated, pureed for soups, boiled or roasted.
