Detailed information on germination capacity

'Lanro' Kohlrabi – proven, cold-resistant outdoor variety with tender, non-woody bulbs.

This variety is a fast-growing kohlrabi with flat-round, whitish-green bulbs weighing up to 200-300 g. The flavor is slightly sweet, juicy, and nutty. It is ideally suited for pre-cultivation, early outdoor growing, and also for cultivation under fleece or foil. Robust, bolt-resistant, high-yielding, and open-pollinated - perfect for self-sufficiency and organic farming.

Origin & History

'Lanro' is an open-pollinated and historical outdoor variety originating in Switzerland (Hilterfingen, Canton of Bern), bred by the Roggli family. It was developed because all kohlrabi varieties at the time tended to bolt early in the open field. With its bolt resistance, cold tolerance, and short cultivation period, it became a proven variety for early outdoor growing and mixed cropping.

Its whitish-green bulbs remain tender even at larger weights and do not become woody. 'Lanro' was traded in Switzerland for a long time and is still considered an open-pollinated variety, preserved today in seed archives by organic seed initiatives.

Appearance & Characteristics

The plant grows compact and upright, reaching about 35 cm in height. It forms robust, flat-round bulbs and bears strong, dark-green foliage. Frost-tolerant down to -3 °C.

Bulb details:

Size: Medium to large, 200-300 g per bulb – larger bulbs also possible
Shape: Flat-round, about 10-12 cm in diameter
Color: Whitish-green with tender, light flesh
Texture: Tender, juicy, non-woody
Flavor: Slightly sweet, juicy, and nutty

Usage & Cultivation Highlights

The bulbs are excellent for fresh consumption, cooking, steaming, frying, and especially for raw salads. Their slightly sweet, juicy, and nutty flavor and tender texture make them a real eye-catcher in vegetable dishes and give meals a special flair. Even larger bulbs do not become woody. The young kohlrabi leaves are also edible and can be prepared like leafy greens.

‘Lanro’ is particularly suitable for early sowing outdoors or under fleece/foil due to its frost tolerance. It matures quickly and delivers stable yields. Even soil moisture prevents the bulbs from splitting. Thanks to its robustness and adaptability, the variety grows reliably outdoors, in greenhouses, and especially in pots. It also provides stable yields under changeable weather conditions.

Compared to other kohlrabi varieties, 'Lanro' is especially tender, fast-maturing, and non-woody – ideal for those who appreciate open-pollinated kohlrabi with quick harvests and reliable yields.

Cultivation guide for

Lanro

Growing difficulty:

Easy

• In subtropical climates pre-cultivation is possible from January - transplant to full sun from mid-March.
• In temperate regions pre-cultivation from March - transplant to full sun from mid-April after frost.
• Sowing in deep, well-drained, humus-rich and nutrient-rich loamy soil - 0.5-1 cm deep. Plant spacing: 25 × 30 cm.

Cultivation tips:

• For a staggered harvest, it’s recommended to sow seeds in intervals of 4 weeks.
• Keep evenly moist - drought stress leads to bolting.
• Good air circulation protects against aphids and fungal diseases.

Storage instructions:

Store seeds in a cool, dry, dark, and airtight environment to maximize shelf life and germination.

Propagation method:

Generative propagation by seed

Propagation:

• This variety is insect-pollinated and cross-fertile, belonging to the species Brassica oleracea.
• For seed production, a minimum isolation distance of 800–1000 m from other varieties of the same species is recommended, as cross-pollination is easily possible.
• The plant is biennial - after flowering it produces long pods with well-maturing small seeds.
• Seeds are ready for harvest once the pods are fully dried and slightly opened.

Sowing & Planting

Germination type:

Dark germinator, Temperate germinator

Sowing depth:

0,5-1 cm

Germination temperature:

15-20 °C

Germination time:

5-10 days

Pot culture:

Requires a minimum container size of 5 liters.

Row spacing for baby leaf:

Crop rotation guidelines:

• Do not plant after other crucifers - at least 3 years interval recommended.
• Repeated cultivation at the same site increases disease pressure, leads to nutrient depletion, and impairs soil structure.
• Ideal previous crops include legumes, onions, root vegetables, and green manure – rotating crops supports healthy soil.
• Crop rotation with low-nutrient-demanding plants is recommended to prevent soil fatigue and maintain healthy growing conditions.
• Plan a green manure crop between heavy-feeding plants and this tomato variety to restore soil fertility.
• Avoid planting directly after heavy-feeding crops – allow the soil to recover and replenish nutrients first.
