How and when to harvest kohlrabi – the ideal time for the best flavor and texture

Fresh harvested kohlrabi whole and sliced on a wooden board.

Kohlrabi is a unique-looking vegetable yet this quirky brassica is becoming increasingly popular among gardeners looking for a delicious and versatile crop to grow and harvest.

I grew both white and purple varieties of kohlrabi for chefs, and it was important to harvest the crop at the peak moment in their lifespan. This is because the taste can turn chewy and bitter if they are left to develop too long in the vegetable garden.
