Culinary Notes


Chef's Note

Winner kohlrabi’s hallmark is that crisp, water-sweet bite—mild enough to eat raw, but still braise-friendly without turning pithy. Its cabbage-bright snap loves sharp acids and salty fats, so it really shines when you dress it hard or pickle it fast.

Best Uses

  • paper-thin or matchstick salads where it stays snappy under vinaigrette
  • quick pickling for crisp, tangy bites
  • roasted wedges in a hot pan until browned on the edges and tender through

Frequently Asked Questions


What pest or disease commonly hits kohlrabi (Brassica oleracea var. gongylodes), and how do I control it at home?
Watch for cabbage worms (imported cabbageworm/diamondback moth larvae) and flea beetles, which can chew irregular holes in kohlrabi leaves. Use row cover over seedlings until plants are well established, and if you see larvae, hand-pick early and spray with Bacillus thuringiensis (Bt) following label directions. If you notice yellowing with damp, brown stems or leaf spots, remove affected leaves and avoid wetting foliage during watering to reduce fungal spread.
How often should I water kohlrabi during its main growth to avoid tough or split bulbs?
During the main bulbing phase, keep the soil consistently evenly moist—about 1 inch (2.5 cm) of water per week, split into 2–3 waterings if it’s hot. Let the top 1 inch (2.5 cm) dry slightly between waterings, but don’t allow the bulb to experience repeated drought then heavy watering, which can lead to cracking and pithiness. Mulch around plants to steady moisture in full sun beds.
When is kohlrabi (Brassica oleracea var. gongylodes) ready to harvest, and what size should I pick?
Harvest when the swollen stem/bulb is tender and reaches about 2.5–4 inches (6–10 cm) across, usually around 55 days from sowing. If you wait until the bulb is much larger or the skin looks overly thick, it becomes fibrous and less flavorful. Cut the bulb at the base with a sharp knife, then harvest the outer leaves for fresh eating while the inner growth is still young.
