​Turnips are cool-weather vegetables that can be grown both in spring and fall, avoiding the hot summer months. They mature very rapidly and you can enjoy both the greens and the roots. Try this ancient root vegetable that’s been grown for over 3,000 years.

Turnips are hardy biennials usually grown as annuals by the home gardener. We enjoy them most as an autumn crop, seeded in late summer, because they are usually sweeter and more tender than spring crops—and pests are less problematic.

What’s wonderful about turnips is that they germinate in only a few days. Within a month, you can enjoy their bright greens, and within a second month, you can eat the swollen roots. Try them as a substitute for potatoes.


When to Seed

For a late spring harvest, sow turnip seeds directly in the garden as soon as the ground is workable, usually 2 to 3 weeks before the average last frost date. 
For an autumn harvest, sow turnips in late summer. Sow after summer crops of onions, squash, beans or sweet corn.
You can also sow seeds in early autumn for a late autumn harvest.

Planting Instructions

Turnips are seeded directly into the ground; they do not transplant well.
Select a site that gets full sun.
Soil should be well-draining and loosened to a depth of 12 to 15 inches.
In advance, mix in a 2- to 4-inch layer of compost or aged manure. Add sand to heavy, clay soil.
Scatter turnip seed. Do not cover the seeds with more than ½ an inch of soil.
Once seedlings are 4 inches high, thin them to 4 to 6 inches apart. Space wide rows 12 inches apart.
Thin turnips grown for greens from 2 to 3 inches apart (or, some of us don’t bother thinning for greens at all).


Keep the beds weed free.
Mulch heavily.
Turnips do not need much care but consistent soil moisture is important. Keep soil lightly moist, watering at a rate of 1 inch per week to prevent the roots from becoming tough and bitter.

Harvest some turnips very early as turnip greens. The leaves taste best when young and tender.
Harvest early types after about 5 weeks; maincrop types after 6 to 10 weeks.
Harvest turnips at any size you wish, however, the small, young turnips are nicer and more tender.
For fall turnips, consider harvesting just after a light frost (but before a hard freeze) for a sweeter taste. 
Store for up to 3 or 4 months in a cool outdoor place covered with straw.​
