The Basics

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

When to plant

Transplant in February to April, possibly May, or September to October, possibly August.
Direct seed in March to April possibly May, or September to October, possibly August.
If growing your own seedlings, start the seeds 4 weeks before you want to plant

Harvest window

Turnips are typically harvested 2 to 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 to 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.
