  • Azur Star (deep blue)
  • Lanro (white-greenish)
  • Noriko (white)
  • Rasko (creamy white)

Planting distance

  • in the row: 25 to 30 centimeters
  • between the rows: 30 centimeters

The harvest time of large-knobbed kohlrabi is usually in the fall, as they grow more slowly. In return, the tubers almost reach the size of cabbages without becoming woody. Common varieties are:

  • Blari (blue, tuber weight: up to one kilogram).
  • Gigant (white, tuber weight: two to three kilograms)
  • Kossak (white, tuber weight: up to three kilograms)

How Much Space Does Kohlrabi Need To Grow?

Grow the tuber in a raised bed is a fine thing, but quickly leads to space problems. Therefore, you should give preference to small-tuber varieties. You can also save space by planting kohlrabi plants in staggered rows. For this “checkerboard” pattern, proceed as follows:

1st row:

  • first plant: set with about seven centimeters of space between them and the edge
  • After that: leave 15 centimeters of space between the kohlrabi plants.

2nd row:

  • Distance from the 1st row: 15 centimeters
  • first plant: 15 centimeters from the edge
  • put other kohlrabi plants at a distance of 15 centimeters.

The third row corresponds to the first, the fourth to the second, and so on. The planting distance between the rows of kohlrabi is always 15 centimeters.

Tip: Planting kohlrabi plants in a checkerboard pattern is also suitable for a deep bed.

Balcony kohlrabi

For the cultivation of the tuber on the balcony, you should also take into account the space requirements of the plants. Since space is usually limited, it is recommended to use small-tuber varieties here as well. The distance between plants depends on the type of planter:

  • round container: 25 to 30 centimeters in diameter (space for one plant).
  • oblong container: 25 centimeters between the kohlrabi, width 30 centimeters.
