Rutabagas are grown for their large round roots. They are similar to turnips but are larger, slightly sweeter, and take longer to mature. They have yellow skin and flesh. Like other vegetables in the brassica family, they develop their best flavor in cool weather.

Planting
- Direct seed in August and September; thin to 6 to 10 inches apart.
- Transplant 6 to 10 inches apart in September and October.
- If growing your own seedlings, start the seeds 4 weeks before you want to plant.
- Excess nitrogen may cause misshapen roots.
Harvesting
- Harvest when roots reach desired size, typically 3 to 5 inches, in 3 to 4 months. Flavor is best if there have been some light frosts, but protect from hard freezes.
- The shoulders frequently push out of the soil and may be tinted reddish-purple. This is normal and not a problem.
