Growing Kohlrabi in Zone 7A

Kohlrabi is the underrated brassica of the spring garden. It grows fast, tastes like a mild broccoli stem crossed with an apple, and is ready in 45-60 days.

Zone 7A enjoys a long growing season. You can often get two plantings of cool-season crops (spring and fall).

Top Growing Tips

• Start indoors 4 weeks before last frost or direct sow 4 weeks before
• Harvest when the swollen stem (not a root — it grows above ground) is golf-ball to tennis-ball size
• Larger than 3 inches means it’s getting woody and tough
• Tolerates light frost; plant early for spring harvest and again in late summer for fall
• Thin to 5-6 inches apart for proper bulb development

Companion Planting

Good companions: beets, onions, cucumbers, aromatic herbs

Avoid planting near: tomatoes, pole beans, strawberries

Harvest Timeline

45-60 days from transplant; harvest when 2-3 inches in diameter
