Growing Turnips in Zone 10B

Turnips are a fast, cool-season root vegetable that’s often overlooked. Baby turnips are tender and mild; larger ones are earthier and better roasted.

Zone 10B has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

Top Growing Tips

• Direct sow 6 weeks before last frost or in late summer for fall harvest
• Thin to 4-6 inches apart — crowded plants don’t form good roots
• Harvest small (2-3 inches) for sweetest flavor
• The greens are edible and delicious sautéed with garlic
• Fall-sown turnips taste sweeter after a light frost

Companion Planting

Good companions: peas, onions, garlic

Avoid planting near: mustard relatives (can share pests)

Harvest Timeline

35-60 days from seed; best at 2-3 inches in diameter
