Turnips exposing shoulders above ground level

The Basics

Turnips are a cool season root vegetable that grow best between 50–65°F. Higher temperatures may produce strong-flavored roots. The leaves are also edible and are referred to as "turnip greens".

When to plant

• Transplant: February–April (maybe May), September–October (maybe August)
• Direct seed: March–April (maybe May), September–October (maybe August)

Harvest window

• Turnips are typically harvested 2–3 months after planting. Some varieties grow faster while others hold well in the ground. Older turnips may bolt (send up a flower stalk), develop a woody core, and have a strong taste.
• Leaves may be harvested throughout the growing season, a few leaves per plant. Younger leaves will be more tender and milder in flavor.

Care overview

• Thin seedlings to 4–6 inches apart when they are 2 inches tall.
• For a continuous harvest, plant in succession every 2 weeks.
• It is typical for turnips to expose their shoulders above ground level. It is not a problem.
• Turnips are frost hardy but extended temperatures below 30°F may cause damage.
