Best Practices for Harvesting and Storing Kohlrabi for Long-term Use

by

Kohlrabi is a versatile and nutritious vegetable that can be stored for long periods if harvested and stored properly. Knowing the best practices ensures you enjoy fresh kohlrabi even after the growing season ends.

Harvesting Kohlrabi

Timing is crucial when harvesting kohlrabi. The best time to harvest is when the bulbs reach about 2 to 3 inches in diameter. They should be firm and smooth, without cracks or blemishes. Use a sharp knife or garden shears to cut the bulb from the plant, leaving about an inch of stem attached.

Harvesting too early can result in small, underdeveloped bulbs, while waiting too long may cause the bulbs to become woody and less palatable. Regularly check your plants to harvest at the optimal size.

Preparing Kohlrabi for Storage

Before storing, gently wash the bulbs to remove soil and debris. Pat them dry with a clean towel to prevent mold growth. Remove any damaged or diseased leaves to improve storage life.

Storing Kohlrabi for Long-term Use

For short-term storage, place the cleaned kohlrabi in a perforated plastic bag in the refrigerator’s crisper drawer. They can stay fresh for up to two weeks this way.

For longer storage, consider methods such as:

  • Cold Storage: Store in a root cellar or a cool, dark place at temperatures around 32°F (0°C) with high humidity.
  • Freezing: Blanch the bulbs for 2-3 minutes, cool quickly in ice water, drain, and pack in airtight containers or freezer bags. Frozen kohlrabi can last up to 12 months.
  • Pickling: Preserve kohlrabi by pickling in vinegar and spices, creating a tangy snack that lasts for months.

Proper storage conditions are essential to maintain flavor and texture. Avoid storing kohlrabi near fruits like apples or bananas, which emit ethylene gas that can accelerate spoilage.

Tips for Best Results

  • Harvest kohlrabi early in the day for the best flavor.
  • Use sharp tools to prevent damage to the bulbs.
  • Maintain high humidity during storage to prevent dehydration.
  • Label stored kohlrabi with the harvest date to track freshness.

By following these best practices, you can enjoy fresh, crunchy kohlrabi long after the growing season ends. Proper harvesting and storage not only extend shelf life but also preserve the vegetable’s nutritional value and flavor.
