How to Harvest and Store Kohlrabi

Harvest kohlrabi young and tender for the best flavor.

Kholrabi harvestKohlrabi is ready for harvest 40 to 80 or more days after sowing depending on the variety.

Know the variety and days to maturity of the variety you are growing. The tastiest kohlrabi is eaten young and tender. Kohlrabi that grows too large will become woody, tough, and bitter tasting.

Kohlrabi looks like an above-ground root, but it is an enlarged stem with leaves growing out of it. Kohlrabi has the flavor of tender cabbage hearts.

When to Harvest Kohlrabi

  • Harvest spring planted kohlrabi when the enlarged stem is 1 to 2 inches (2.5-5 cm) in diameter.
  • Harvest summer and autumn planted kohlrabi when the stem is 3 to 4 inches (7-10 cm) in diameter.
  • Harvest giant kohlrabi varieties when they are 8 to 10 inches (20-25 cm) in diameter.
  • Kohlrabi that ripens in mild and cool weather will be tastier than kohlrabi that matures in warm and hot weather. Where summers are cool, grow kohlrabi spring through autumn. Where summers are hot, grow kohlrabi in fall and winter.
  • Kohlrabi that matures in cool weather can remain in the ground until temperatures fall into the 20°sF (-6°C). Garden-stored kohlrabi can freeze once or twice in winter and still be edible.

How to Harvest Kohlrabi

Kohlrabi with the leaves attached will keep in the refrigerator for 2 to 4 weeks, without the leaves 2 to 3 months.

How to Store Kohlrabi

  • Store kohlrabi cold and moist, 32°-40°F (0°-4°C) and 95 percent relative humidity. Cold and moist storage is a challenge. A refrigerator is cold but the air is dry. Place kohlrabi in a perforated plastic bag in the vegetable crisper section.
  • Kohlrabi with the leaves attached will keep in the refrigerator for 2 to 4 weeks, without the leaves 2 to 3 months.
  • If there is no room in the refrigerator, kohlrabi can also be packed in a container—a bucket or plastic storage box or cooler–in moist sand, peat moss, or sawdust. Don’t pack stems too tightly; if the stems touch they can start to rot; be sure to leave 2 inches (5 cm) of insulating material around at the top, bottom, and sides of the stored roots. Set the lid loosely so that there is good air circulation and place the container in as cool a place as possible short of freezing such as a basement, garage, or shed.
  • Check roots in storage often and remove any that show signs of deterioration. If stored stems get too warm they will sprout new tops and become woody.
