Kolibri F1

Family: Brassicaceae Vegetable

Sweetly crisp and delicately nutty, Kolibri F1 forms compact, globe-like kohlrabi with a tender, juicy bite and a smooth, satiny skin.

The flesh stays pleasantly mild as it matures, making these bulbs especially satisfying for fresh use and quick turnarounds in the garden. Grow Kolibri F1 for reliable, early harvests—48 days to maturity—when you want uniform shape, clean flavor, and a refreshing crunch in every planting.

Culinary Notes

Chef's Note

Kolibri F1’s satiny skin and juicy, mild flesh keep their sweet-nut snap—so it behaves beautifully raw, not just cooked. Treat it like a crunchy vegetable you can season hard (citrus, mustard, dairy) and it’ll stay composed instead of getting cabbagey or woody.

Best Uses

thin shaved raw into salads where it stays snappy
quick-pickled rounds for a clean sour-crunch
seared or blistered slices with a fast pan glaze (won’t turn harsh)
lightly steamed then dressed—hot but not softening into mash

Flavor Profile

sweetly crisp bite delicately nutty, brassica-sweet tender, juicy crunch with mild flavor

Frequently Asked Questions

What pest or disease commonly affects Kohlrabi (Brassica oleracea var. gongylodes), and how can I control it?

Watch for cabbage worms and flea beetles on kohlrabi leaves, which can cause ragged foliage and slow down bulbing. Use row covers over the plants until they’re well-established, and hand-pick larvae or spray a labeled Bt (Bacillus thuringiensis) when you see caterpillars. If you notice black, water-soaked stem bases or wilting seedlings, remove affected plants and avoid wetting the crown; ensure good airflow between rows.

How often should I water kohlrabi during the main growing phase to form good bulbs?

During the bulbing phase (roughly weeks 3–6), keep the soil evenly moist—about 1 inch of water per week, split into 2–3 waterings if it’s hot or windy. Don’t let the kohlrabi dry out and then flood it, because that can lead to tough texture and cracking. Aim for moisture at the root zone while letting the surface dry slightly between waterings.

How do I tell when kohlrabi is ready to harvest?

Harvest when the swollen stem (“bulb”) is about 2–3 inches across and feels firm, typically around 48 days from sowing for early types like yours. If you can still easily dent it with a fingernail, it’s usually in the sweet spot; if it gets larger but becomes woody or hollow-sounding, it’s overmature. Cut the bulb at the base and cool it quickly for best flavor.
