Can I grow kohlrabi at home, and what are the requirements for cultivation?
Kohlrabi can be grown at home, provided you have the right climate and soil conditions.

To grow kohlrabi at home, start by preparing the soil with a mix of compost and well-rotted manure. Sow the seeds directly into the ground, about 1-2 inches deep and 2-3 inches apart. Keep the soil consistently moist during the first few weeks after planting, and then reduce watering to about 1-2 inches per week.
