Turnips are a cool season root vegetable that grow best between 50 and 65°F. Higher temperatures may produce strong-flavored roots. The leaves are edible and are referred to as “turnip greens”.
Cultural Tips for Growing Turnip, UC IPM
Planting
- Direct seed 2 to 3 inches apart in March to April or in September to October, possibly in May or August depending on weather or local conditions. Thin to 4 to 6 inches apart when they are 2 inches tall.
- Transplant 4 to 6 inches apart in February to April or September to October, possibly in May or August depending on weather or local conditions.
- If growing your own seedlings, start the seeds 4 weeks before you want to plant.
- For a continuous harvest of young, tender turnips, plant in succession every 2 weeks.
Harvesting
- 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.
- 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.
