We Recommend

We Recommend: Kolibri (KH434). We don’t recommend this wonderful hybrid kohlrabi for any other reason than how splendid looking it is in the garden. Kolibri has the same fine flavour and texture as Kongo, but hey – it’s bright purple! More gardeners need to grow familiar with this nutritious, easy-to-grow vegetable.

Season & Zone

Season: Cool season
Exposure: Full-sun

Timing

Timing
Direct sow several times during the four to six weeks after the last frost date for a crop to mature starting in about 8 weeks. Sow again after mid-July to early August for fall and winter crops. Planting between mid-May and mid-July causes kohlrabi to mature in hot weather, resulting in inferior bulbs. In short season areas, start kohlrabi indoors in cell trays about 4 weeks before the last frost date and transplant out once day time temperatures are steadily above 10°C (50°F). Optimal soil temperature for germination: 10-30°C (50-85°F). Seeds should germinate in 7-10 days.

Starting

Starting
Sow seeds 5mm (¼”) deep with plants spaced 10-15cm (4-6″) apart in rows 30-45cm (12-18″) apart.

Days to Maturity:

Days to Maturity: From direct sowing.

Growing

Growing
Ideal pH: 6.0-6.8. Kohlrabi is a moderate to heavy feeder that does best in humus-rich soil amended with composted manure. Mix ¼-½ cup complete organic fertilizer into the soil under each plant.

Harvest

Harvest
Spring-sown kohlrabi will get larger than tennis balls in fair soil, but if you pick them when they are still less than 5-8cm (2-3″) in diameter they will be sweet and tender. Fall-grown kohlrabi can grow larger yet stay tender. Kohlrabi is frost-hardy, and may last well beyond Christmas in mild winter areas.

Seed Info

Seed Info
In optimal conditions, at least 80% of the seeds will germinate. Usual seed life: 3 years. Per 100′ row: 360 seeds, per acre: 104M seeds.

Diseases & Pests

Diseases & Pests
Protect from cabbage moths and other insect pests with floating row cover. Prevent disease with a strict 4-year crop rotation; avoiding planting Brassicas in the same spot more than once every four years.

Companion Planting

Companion Planting
A worthy companion for beets, Brassicas, cucumbers, and onions. Avoid planting near peppers, pole beans, strawberries, and tomatoes.
