Kohlrabi needs to be planted in direct sunlight. The soil needs to be deep, fresh, with organic substances and very well drained. It needs a medium consistency soil that is quite moist. The ground needs to be rich in organic substances and nutritional elements.


Kohlrabi must be planted in well-tended soil, enriched with compost. It is a hardy vegetable, although it excels in a soil with pH values ranging from 5.5 to 6.8.


Good drainage is useful to prevent mould and rust in kohlrabi plants and therefore, it is necessary to plant out in an area that is not waterlogged. Kohlrabi needs a lot of water and grows best in relatively mild or Mediterranean climates. If the soil is dry, insufficiently watered kohlrabi will become woody and unpleasant to eat. Fertilise with humus or ripe manure when preparing the soil before planting.


Kohlrabi is subject to infestation from beetle larvae. Slugs and snails will feed on the leaves. Hoe regularly between the rows and keep weed growth in check.  Kohlrabi is easily damaged in the early stages and the roots grow very close to the surface, given that the bulb is above soil level. The most critical period for the plant is the first couple of weeks.
