Rutabagas, or swedes, are a biennial typically grown as an annual. They are root vegetables grown for both their golden root and their greens. Here’s how to plant and grow rutabagas in your garden.

Rutabagas are often mixed up with turnips. They require very similar care to turnips, though they take longer to reach maturity. Unlike turnip greens, rutabaga foilage is smooth, waxy, and blue-green. The root is usually yellow-fleshed, while turnip roots are generally white-fleshed.

Rutabaga is a cool-weather crop, and it tolerates frost and drought. It is primarily grown in the northern United States, Canada, and northern Europe.

Planting

Select a site that gets full sun. Soil should be well-drained.
Sow seeds as soon as you can work the soil. Plant seed 2 inches apart and ½-inch deep in early to mid-summer, about three months before the expected harvest.
Rows should be 14 to 18 inches apart.
Seeds should germinate in 4 to 7 days in 45ºF to 85ºF weather. Sustained average temperature over 80ºF might cause excessively fast growth, called “bolting.”
After germination, rutabagas should be thinned to 6 inches apart.

Care

Fertilizers can be applied when the seeds are planted, and nitrogen and organic material can be beneficial to rutabagas. Learn more about soil amendments.
Water at a rate of 1 to 1-½ inches per week, either with rainwater or irrigation. Watering is most important as the roots reach maturity.
Control weeds in the area with frequent, shallow irrigation.

Pests/Diseases

Flea beetles
Root maggots
Aphids
Wireworms
Root diseases like clubroot and root knot
White rust

Harvest/Storage

Rutabagas are ready to harvest when the roots are 2 to 3 inches in diameter. Roots at this size will be especially tender.
It is best to wait until the roots are 4 to 5 inches in diameter for optimal taste.
Rutabagas taste best if harvested after a few light frosts.
Rutabaga foliage can be harvested along with the roots.
Before storing rutabagas, the foliage should be cut off to within 1 inch of the crown with a sharp knife. They can be stored for about 4 months at temperatures just above freezing and in a damp environment with 90 to 95 percent humidity.
