• Temperature: Sudden changes in temperature, especially prolonged exposure to high temperatures, can induce bolting in kohlrabi plants.
• Day Length: Kohlrabi is a short-day plant, meaning it requires shorter daylight hours to thrive. Extended periods of daylight can stimulate bolting.
• Maturity: Planting kohlrabi too late in the season can increase the likelihood of bolting, as the plant may not have enough time to develop before the onset of warmer weather.
• Stress: Environmental stressors, such as drought or nutrient deficiencies, can also trigger bolting in Early White Vienna Kohlrabi.

Preventive Measures to Avoid Bolting

Fortunately, there are several strategies you can employ to prevent Early White Vienna Kohlrabi from bolting:

Proper Timing: Plant Early White Vienna Kohlrabi early in the season, ensuring that it has enough time to mature before the onset of hot weather. Consult local planting calendars or seek advice from experienced gardeners to determine the optimal planting time for your specific region.

Temperature Control: Protect kohlrabi plants from extreme temperature fluctuations by providing shade during hot periods or using row covers to moderate temperature and humidity levels.

Day Length Manipulation: If you are growing Early White Vienna Kohlrabi in a controlled environment, such as a greenhouse, you can manipulate day length by using blackout curtains or artificial lighting to mimic shorter daylight hours.

Proper Irrigation: Ensure that your kohlrabi plants receive consistent and adequate water supply to prevent drought stress, which can trigger bolting. Mulching around the plants can help retain soil moisture.

Optimal Nutrient Management: Maintain proper soil fertility by regularly testing and amending the soil with organic matter and balanced fertilizers. This will help prevent nutrient deficiencies that can contribute to bolting.
