How to Grow Turnips: The Complete Guide

Turnip (Brassica rapa subsp. rapa) is a easy-to-grow cool-season vegetable that thrives in USDA zones 2-9. With the right soil, sunlight, and care, you can harvest fresh turnip in as little as 30-60 days. This guide covers everything you need to know about growing turnip at home—from planting to harvest.

Overview

Turnips are underrated dual-purpose crops offering mild, sweet roots and tender, nutritious greens. Japanese varieties like Hakurei are sweet enough to eat raw, while traditional types are perfect roasted or mashed.

When and How to Plant Turnips

Start indoors: Not recommended—direct sow. Turnip needs full sun and loose, well-drained, ph 6.0-7.0 to thrive. Plant seeds at ¼ in depth with 4-6 in between plants.

• Sowing depth: ¼ in
• Plant spacing: 4-6 in
• Germination time: 3-5 days
• Days to harvest: 30-60 days
• Best soil: Loose, well-drained, pH 6.0-7.0
• Season: Cool season — zones 2-9

Care and Maintenance

Turnip requires regular watering and full sun. Consistent moisture is especially important during the growing season when roots are establishing.

• Watering: Regular — water deeply at the base, not overhead, to prevent leaf disease
• Mulching: Apply 2-3 inches of straw or shredded leaves to conserve moisture and suppress weeds
• Feeding: Apply balanced organic fertilizer or compost tea every 3-4 weeks during active growth
• Watch for deficiencies: Yellow leaves = nitrogen, purple stems = phosphorus, brown leaf edges = potassium

Pro Tips

Baby turnips (harvested at golf-ball size) are tender and sweet. Fall-planted turnips are sweeter than spring ones as cold converts starches to sugars.
