Find helpful answers about kohlrabi seed planting, harvesting, and growing this unique vegetable in your home garden.
Kohlrabi generally takes around 45–60 days from sowing to reach harvest size, depending on the variety and growing conditions. Seeds usually germinate within 5–10 days in suitable soil temperatures. Harvest the swollen stems while they are still small and tender for the best texture and flavor.
The best time to plant kohlrabi seeds is during cool weather in early spring or late summer. For a spring crop, sow seeds several weeks before the last expected frost. For a fall harvest, plant in late summer so the developing stems mature as temperatures become cooler.
Kohlrabi may fail to develop properly swollen stems because of overcrowding, inconsistent watering, excessive heat, poor soil fertility, or insufficient sunlight. Provide adequate spacing, fertile well-drained soil, regular moisture, and cool growing conditions. Harvest at the recommended size to maintain tender, crisp stems.
