Growing kohlrabi can be a rewarding experience for gardeners aiming for a continuous harvest of this versatile vegetable. Timing your planting is crucial to ensure a steady supply throughout the growing season. Understanding the best time of year to plant kohlrabi will help you maximize your yields and enjoy fresh kohlrabi from late spring to fall.
Understanding Kohlrabi Growth Cycles
Kohlrabi is a cool-season crop that thrives in moderate temperatures. It prefers daytime temperatures between 60°F and 75°F (15°C to 24°C). When temperatures rise above 80°F (27°C), the plant’s growth can slow down, and it may become woody or bolt prematurely. Conversely, very cold temperatures can damage young plants or delay growth.
Best Planting Times for Continuous Harvests
The key to a continuous harvest is to stagger planting times throughout the growing season. Here are general guidelines based on your climate zone:
- Spring Planting: Sow seeds 2-4 weeks before the last expected frost date. In most temperate regions, this means planting from late March to early April.
- Summer Planting: For a second crop, plant seeds 6-8 weeks after the first harvest begins, typically in late June or early July.
- Fall Planting: In areas with mild winters, you can plant a fall crop 8-10 weeks before the first expected frost to enjoy fresh harvests into late autumn.
Additional Tips for Success
To ensure a successful continuous harvest, consider these tips:
- Succession planting: Sow new seeds every 2-3 weeks during the growing season.
- Temperature management: Use shade cloths or row covers to protect young plants from extreme heat.
- Soil preparation: Ensure well-drained, fertile soil rich in organic matter for optimal growth.
- Watering: Keep soil consistently moist but not waterlogged.
By timing your plantings carefully and following these tips, you can enjoy a steady stream of fresh kohlrabi throughout the growing season. Happy gardening!
