Kohlrabi - White Vienna
This bulbous vegetable is often referred to as the cabbage turnip, but with the virtues of neither. The bulbs, whether green or purple, are sweeter, juicier, and crisper than turnips, with the mild flavor of broccoli stems

Sprinkle evenly on top of coco coir, filtered soil, or other growing medium until it covers the entire surface.
Mist with a mister. Mist twice a day - in the mornings and in the evenings. Keep covered in darkness for the first 3-4 days. Remove cover after 3-4 days, and continue to mist twice daily.
Harvest after 10 days
Kohlrabi prefers fertile, well-drained soil rich in organic matter for best growth. Most soils in Utah are suitable for kohlrabi production.
Before planting, incorporate 2-4 inches of well-composted organic matter and apply 4-6 cups of all-purpose fertilizer (16-16-8 or 10-10-10) per 100 square feet.
Kohlrabi can be grown from seed or transplants. Seeds should be planted ¼-¾ inch deep and thinned to the final stand when plants have 3-4 true leaves. Plants removed at thinning can be transplanted to adjacent areas. Transplants can be used to provide earlier harvest. Transplants should have 4-6 mature leaves and a well developed root system before planting. Generally 4-6 weeks are required to grow transplants to this size.
Seeded or transplanted kohlrabi should be spaced 6 inches between plants in the row with rows 1 foot apart. Kohlrabi grows best when temperatures do not exceed 75°F. Young plants may be damaged by hard frosts. Mature plants will flower if average temperatures during growth are less than 45°F. Transplants may be planted 1-2 weeks before the last frost date for the growing area. Seeded kohlrabi may be planted at the same time. For fall maturing kohlrabi, select early maturing cultivars and plant 50 days before the anticipated maturity date. The maturity date can be timed for 2-3 weeks after the first fall frost. High summer temperatures reduce growth, decrease quality, and cause the enlarging stems to become tough and woody. In hot areas it is best to grow kohlrabi as a spring or autumn crop.
Water kohlrabi frequently, since roots are shallow. About 1-2 inches of water are required per week. Use drip irrigation if possible to conserve water. Applying mulch around the plant also helps conserve soil moisture and reduces weed growth. Moisture fluctuations will cause the stems to become tough and woody.
Apply 1 cup per 10 feet of row of a nitrogen-based fertilizer (21-0-0) 3 weeks after transplanting or thinning to encourage rapid plant growth. Place the fertilizer 6 inches to the side of the plant and irrigate it into the soil.
Plastic mulches can help conserve water, reduce weeding and allow earlier planting and maturity, especially with transplants. Fabric covers are used to protect seedlings and transplants from frosts and insect pests. Apply organic mulches when summer temperatures increase. These will cool the soil and reduce water stress. Organic mulches such as grass clippings, straw, and newspaper also help control weeds.
