Depending on the variety, the swollen stems can grow considerably larger than those of standard kohlrabi while remaining tender when grown and harvested appropriately. Choose fertile soil, consistent moisture, and suitable cool-weather conditions to encourage healthy growth.

Discover helpful information about giant kohlrabi size, growing conditions, and harvesting.
The size of Giant Kohlrabi depends on the cultivar. Certain giant varieties, such as Gigante and Superschmelz, can develop exceptionally large swollen stems while retaining good texture under suitable growing conditions. Check the variety description for its expected mature size and recommended harvest stage.
Kohlrabi may develop undersized swollen stems when plants are crowded, soil fertility is inadequate, moisture is inconsistent, or temperatures are too warm. Provide suitable spacing, fertile soil, regular watering, and cool growing conditions to encourage better stem development.
Harvest according to the recommended size and maturity period of your specific cultivar. Many standard kohlrabi varieties are best harvested while relatively small, whereas selected giant varieties can remain tender at larger sizes. Avoid delaying harvest beyond the variety's recommended stage, and maintain consistent moisture throughout growth.
