Did you planted your kohlrabi somewhere where it can get a full day of sunlight?
Did you planted your kohlrabi in well-drained soil, rich in organic matter and with good moisture?
Did you planted your kohlrabi during the cooler period of the year so you can harvest it before temperatures get high?
Do you water your kohlrabi regularly?
Do you feed your kohlrabi regularly?
Do you harvest your kohlrabi when the bulbs are between 2 and 3 inches in diameter?
Do you keep your kohlrabi free of pests and diseases?
Kohlrabi needs a full day of sun to grow plump and develop its characteristic flavor. Because kohlrabi is a fast, early-season vegetable, you may be able to plant it near deciduous trees that haven't leafed out yet.
Although kohlrabi isn't a root vegetable, it needs the same growing conditions like carrots or radishes: moist, rich, loam. Double digging or raised beds will yield kohlrabi bulbs with tender, non-pithy flesh.
Like many cruciferous vegetables such as broccoli and Brussels sprouts, kohlrabi grows best in cool weather. When summer temperatures arrive, kohlrabi is done growing. Plants you didn't get around to harvesting will be prompted by warm weather to bolt, or produce flowers.
Keep kohlrabi well-watered, which shouldn't be difficult in cool spring soils. For a nutrient boost, water with compost tea each time.
Kohlrabi is a heavy feeder. It's better to feed the plants continuously by enriching the soil with amendments that improve tilth than to add chemical fertilizers. Add manure at planting time, and side-dress rows with compost until harvest.
Kohlrabi doesn't go through a very noticeable color change as it ripens, but you can rely on the size as a determinant of harvest-readiness. Young bulbs and foliage have the best texture and flavor, so pull the whole plant when the bulbs are between 2 and 3 inches in diameter. Store bulbs in a cool, dry place until you are ready to cook or add to salads. The bulbs will keep for a month in the refrigerator.
God job! You are taking good care of your kohlrabi.
Prevent cutworms by spreading diatomaceous earth around young plants, or by using collars around plants. Handpick caterpillar pests like the cabbage worm. You can also remove egg clusters from the undersides of leaves.

Hi! I’m Sreten Filipović. I graduated from the Faculty of Agriculture at the University of Belgrade, with a master's degree in Environmental Protection in Agricultural Systems. I’ve worked as a researcher at Finland's Natural Resources Institute (LUKE) on a project aimed at adapting south-western Finland to drought episodes. I founded a consulting agency in the field of environment and agriculture to help farmers who want to implement the principles of sustainability on their farms. I’m also a founding member of the nonprofit organization Ecogenesis from Belgrade whose main goal is non-formal education on the environment and ecology. In my spare time, I like to write blog posts about sustainability, the environment, animal farming, horticulture, and plant protection. I’ve also published several science-fiction short stories.
