Early White Vienna
As the name suggests, kohlrabi was developed in Germany. It is sometimes said to be a cross between a cabbage and a turnip, but that may be just because it seems like one.

Kohlrabi needs full sun, and should not be planted where another Brassica has grown in the previous three years, as it can lead to disease and pest problems. Kohlrabi generally does better as a fall crop, sown 6 to 8 weeks before the first autumn frost date. Autumn Kohlrabi bulbs can be allowed to get larger than 2" to 3", because cold weather seems to keep them tender (it also increases their sweetness).
For spring planting, sow the first crop 4-6 weeks before the last frost date. You can make several succession sowings (very early sowings may be vernalized and bolt).
In cool climates, you can continue to succession sow all summer.

Keep the soil evenly moist or the bulbous stems may turn woody. Fortunately this isn't often an issue with this cool weather crop.
Low nitrogen. High potassium. High phosphorous. It's a light feeding crop and doesn't need a lot of nitrogen, but it does like potassium (add greens and or wood ashes). It also likes calcium.
- Tolerates light frost
- Small Gardens?
While kohlrabi isn't particularly well suited for container growing, it can be done in a large container. Ideally, one that is 8-12 inches deep and 12-18 inches wide. If planting multiple plants in one container, make sure they are spaced 18-24 inches apart.
