Yes, kohlrabi can be grown in containers, provided you have a large enough pot with good drainage. Choose a container that is at least 6-8 inches deep and has a diameter of 8-10 inches. Make sure the pot has drainage holes to prevent waterlogged soil.
When growing kohlrabi in containers, use a well-draining potting mix and keep the soil consistently moist. Provide full sun to partial shade, and fertilize regularly.

How do I store kohlrabi to keep it fresh for a longer period?
To keep kohlrabi fresh for a longer period, store it in the refrigerator. Remove any leaves or stems, and place the bulb in a plastic bag or airtight container. Keep the kohlrabi away from strong-smelling foods, as it can absorb odors easily.
For longer-term storage, kohlrabi can be stored in a cool, dark place, such as a root cellar. Make sure the bulb is dry and free of any damage or bruises. You can also store kohlrabi in the freezer, either whole or chopped. Simply blanch the kohlrabi in boiling water for 2-3 minutes, then chop and freeze in airtight containers or freezer bags.
