Do Rutabagas Need Full Sunlight?

Sunlight Requirements

• Like turnips, rutabagas grow best in areas that receive full sunlight. They also tolerate partially sunny locations, however, and in very hot climates might do better in partial shade. If you decide to plant rutabagas from seed, cover the seeds with only about 1/4 to 1/2 inch of soil to ensure they receive enough sunlight.

Temperature

• Although adequate sunlight is an important factor in rutabaga growth, temperature is probably the most crucial element. Rutabagas require at least 90 days to reach maturity, and temperature changes trigger periods of new growth. When grown in warm climates, rutabagas often develop a tough, bitter taste and lack their characteristic sweetness. In cooler climates, plant rutabagas in late summer for a winter harvest. In warm climates, plant rutabagas in early autumn.

Other Factors

• If rutabaga plants are in the correct sunlight and temperature conditions but do not thrive, then the soil could be to blame. Although rutabagas are not too picky about their soil site, they are susceptible to boron deficiency and may not develop healthy root systems in soil that has a high content of nitrogen or organic matter. For optimal growing success, plant rutabagas in a soil with a pH from 6.0 to 6.5.

Common Problems

• Rutabaga plants may develop disease or insect problems. Rutabagas grown in a soil site previously used to grow turnips or rutabagas have a higher chance of root maggot infestation. To prevent root maggots, sprinkle the soil with wood ashes or cover the plants with cheesecloth. Other insect pests that affect rutabaga plants include wireworms, flea beetles and turnip aphids. Common rutabaga diseases include black leg, black rot and turnip mosaic virus.
