Kohlrabi Seeds | Crunchy, Cool-Season Brassica

Kohlrabi

Kohlrabi (Brassica oleracea var. gongylodes), also called German turnip, is a cool-season, fast-growing bulbous vegetable related to cabbage and broccoli. At Seedmart, we offer heirloom and open-pollinated kohlrabi seed varieties selected for robust germination, consistent yields, and adaptability across Australian climates.

Kohlrabi thrives in full sun, rich, well-drained soil, and can be harvested in just 8–10 weeks. Its crunchy, mildly sweet stems are versatile—perfect raw in salads, or cooked in stir-fries, soups, and roasting. All of our kohlrabi seeds are non-GMO and chosen for flavour, texture, and reliable performance in home and market gardens.

Where Can You Grow Kohlrabi?

Kohlrabi prefers full sun and fertile, well-drained soil. Sow seeds directly in garden beds or pots in cooler months—typically late summer, autumn, or spring, depending on your region. Space seedlings 10–25 cm apart in rows 30–40 cm apart. Keep soil moist and mulch to support growth and prevent stress.
