Rutabagas are a hardy vegetable that grow best in cool weather.

Spring Planting

Rutabagas are sensitive to heat, and only grow well when temperatures are 75°F and cooler. For most areas they should be planted in the fall only.

Fall Planting

Plant seeds 14 weeks before the frost.

If you live in a mild climate with a late or no fall frost date (after Nov 1), you might be able to grow turnips all during the winter.

Soil and Fertilizer

Rutabagas grow best in a rich soil and are susceptible to boron deficiency; amend with lots of compost and fertilizer (chemical or organic) at planting.

Fertilizer: 16-16-8 at planting, Borax at planting.


Harvest when tops are 6-8″ tall and roots are 4-5″ in diameter.
