Characteristics of Kohlrabi Oscar F1:
-
Appearance: Kohlrabi Oscar F1 produces a rounded, bulbous stem that is edible. The bulb can range in color from pale green to purple, depending on the variety. The plant also has green leaves that can be used in cooking.
-
Flavor and Texture: The bulb has a crisp, juicy texture with a mildly sweet and slightly peppery flavor, similar to a blend of radish and cabbage.
Growing Tips:
-
Climate: Kohlrabi grows best in cool to moderate temperatures, ideally between 55-75°F (13-24°C). It is a cool-season crop and can tolerate light frosts, which can even enhance its flavor.
-
Soil: Prefers well-drained, fertile soil with a pH of 6.0 to 7.0. Enrich the soil with compost or well-rotted manure to promote healthy growth.
-
Spacing: Space seeds or seedlings about 6-8 inches apart in rows, with rows spaced 12-18 inches apart. This spacing allows for the development of the bulbous stem.
-
Watering: Keep the soil consistently moist but not waterlogged. Regular watering is important for the development of a firm, crisp bulb. Avoid letting the soil dry out, as this can lead to tough and woody bulbs.
-
Fertilization: Use a balanced fertilizer or compost to support growth. Kohlrabi benefits from additional nutrients, particularly nitrogen, which promotes healthy foliage and bulb development.
Uses:
-
Fresh: Kohlrabi can be eaten raw, often sliced or julienned in salads. It has a crisp texture and a mild, refreshing flavor.
-
Cooked: The bulb can be cooked in various ways, including steaming, roasting, or sautéing. It can be used in soups, stews, and stir-fries, where it adds a mild, slightly sweet flavor.
-
Leaves: The leaves are edible and can be used similarly to other leafy greens. They can be sautéed, used in soups, or added to salads.

-
Nutritional Value: Kohlrabi is low in calories and provides essential nutrients such as Vitamin C, Vitamin K, Vitamin B6, and potassium. It also offers dietary fiber and antioxidants.
-
Health Benefits: Known for its potential health benefits, including supporting immune function, aiding digestion with its fiber content, and contributing to overall health through its antioxidant properties.
Additional Tips:
-
Harvesting: Kohlrabi bulbs should be harvested when they reach 3-4 inches in diameter. The bulb should be firm and smooth. Overgrown bulbs can become tough and woody. For best flavor and texture, harvest before the bulbs reach their maximum size.
-
Pest Management: Watch for pests such as aphids, caterpillars, and flea beetles. Regular inspection and maintaining good garden hygiene can help manage these issues. Using row covers can protect plants from pests and harsh weather conditions.
