How to grow Kohlrabi

How to grow Kohlrabi

Learn How to grow Kohlrabi with our easy step by step guide. Kohlrabi is also referred to as German turnip it's very closely related to brussels sprouts, cabbage, broccoli, and cauliflower.

Kohlrabi Varieties

There are several varieties commonly available, 

  • White Vienna,
  • Purple Vienna,
  • Grand Duke,
  • Gigante,
  • Purple Danube,
  • White Danube.

The colouration of the purple types is superficial, as the edible parts are all pale yellow.

Kohlrabi, much over 5 cm in size, tend to be woody, as do full-grown kohlrabi much over perhaps 10 cm in size, except for the Gigante cultivar,  which can achieve great size while remaining of good eating quality.

How to plant Kohlrabi

The kohlrabi plant is easy to grow, usually quite productive, and often accepted as a substitute for turnips.

When growing from seeds, sow outdoors as soon as the soil can be worked, sowing seeds at a depth approximately three times the diameter of the seed.

Otherwise you can start planting seedlings indoors. Transplant them outside a couple of weeks before the last frost, spacing plants 10-20cm.

Kohlrabi prefers cool weather, and that’s the period when most growth will occur.

Kohlrabi Growing Guide

Select a location with full sun for growing kohlrabi plants.

Kohlrabi doesn’t need a deep soil, as it is the stem that grows into a bulb. A well-drained soil that’s watered regularly is quite beneficial. Also plenty of compost and manure or a general purpose fertiliser will help to promote quick growth.

It is not prone to the root weevils that plague turnips, and also less affected by drying winds and heat.

How to Harvest Kohlrabi

It can usually be harvested in 8-10 weeks. The fruit has good standing ability for up to 30 days after maturity, and the approximate weight is 150 gm.

How to use Kohirabi

The flavour of kohlrabi is similar to that of the turnip, but is milder and sweeter when harvested before it becomes too old and tough.  The young stem in particular can be as crisp and juicy as an apple, although much less sweet. 

Kohlrabi can be eaten raw as well as cooked, and the leafy greens can also be eaten. Considered rich in vitamins and dietary fibre, fresh kohlrabi stem is also a good source of vitamin-C. It’s believed to help our body maintain healthy connective tissue, teeth and gum.
