Plant them 1/4 inch deep in seed trays filled with a high-quality potting mix, maintaining a temperature of 60°F-70°F for optimal germination. Once the seedlings have developed 2-3 true leaves and the weather has warmed, transplant them outdoors, spacing them 4-6 inches apart. Water thoroughly after transplanting.

Harvesting: ‘Purple Vienna’ kohlrabi is ready to harvest when the bulbs reach 2-3 inches in diameter, typically 55-65 days after sowing. The bulb should be firm and crisp, with a sweet, mild flavor. Harvest by cutting the bulb at the base, leaving the root in the soil. For the best taste and texture, harvest when the bulbs are young and tender, before they become tough or woody.
