How to Grow Kohlrabi in a Climate with Short Summers

by

Growing kohlrabi in regions with short summers can be a rewarding experience if you understand the right techniques and timing. This cool-season vegetable thrives when planted at the right time and under suitable conditions. In this article, we will explore how to successfully grow kohlrabi in a climate with limited warm weather.

Understanding Kohlrabi and Its Growing Requirements

Kohlrabi, a member of the cabbage family, prefers cool temperatures and can be grown in early spring or late summer. It requires well-drained soil rich in organic matter, consistent moisture, and plenty of sunlight. Short summers mean you need to plan your planting schedule carefully to maximize growth within the limited warm months.

Timing Your Planting for Short Summers

The key to growing kohlrabi in a short summer climate is to plant early. Start seeds indoors 4-6 weeks before the last expected frost date. Transplant seedlings outdoors once the soil warms up and the danger of frost has passed. Alternatively, directly sow seeds outdoors as soon as the soil can be worked.

In regions with very brief warm periods, consider using season extension methods such as row covers or cold frames. These can help protect young plants from unexpected cold snaps and extend the growing season.

Growing Tips for Success

  • Choose fast-maturing varieties: Select kohlrabi varieties that mature in 45-55 days to ensure harvest before the end of summer.
  • Optimize soil conditions: Enrich soil with compost and ensure good drainage.
  • Maintain consistent moisture: Keep the soil evenly moist to promote tender, flavorful bulbs.
  • Provide ample sunlight: Aim for at least 6 hours of direct sunlight daily.
  • Use season extension: Employ row covers or cold frames to protect plants from cold nights.

Harvesting and Storage

Kohlrabi is ready to harvest when the bulbs reach about 3-4 inches in diameter. Use a sharp knife to cut the bulbs from the plant, leaving a small stem attached. For storage, keep the harvested kohlrabi in the refrigerator in a plastic bag for up to a week. Freshly harvested kohlrabi can also be preserved by freezing or pickling.

With proper planning and care, you can enjoy fresh, homegrown kohlrabi even in climates with short summers. Its crisp texture and mild flavor make it a versatile addition to salads, stir-fries, and side dishes.
