Planting & Care

Kohlrabi germinates best in temperatures 45 F to 85 F
Direct sow outdoors in early spring at least 4 weeks before last frost date and continually every 2 to 3 weeks for an ongoing spring and summer harvest. Plant seeds 1/2 inch deep and 1 inch apart in rows 12 inches apart - thin seedlings to 6 inches
The thinned seedlings can be moved to open spaces in the garden or eaten
For an earlier spring harvest, start seeds indoors and transplanted as soon as the ground can be worked
For a fall harvest, begin sowing seeds about a month before the first frost
Use floating row covers to protect plants from insects and plunging temperatures
