Growing turnips (Brassica rapa) can be a rewarding endeavor for Ohio gardeners. This versatile root vegetable is not only easy to cultivate, but it also thrives in Ohio’s diverse climate. This article will provide you with a comprehensive guide on how to successfully grow turnips in the Buckeye State.
Turnips are biennial plants cultivated as annuals for their edible roots and greens. They belong to the Brassicaceae family, which includes cabbage, broccoli, and kale. Turnips are known for their mild flavor, making them an excellent addition to various dishes, from soups and stews to salads. They are also packed with nutrients, including vitamins A, C, and K, as well as fiber.
When growing turnips in Ohio, selecting the right variety is crucial. Several types of turnips are available, each with its unique characteristics:
Purple Top White Globe: This popular variety has a white bulb with a purple top. It is well-suited for fall planting and can grow up to 6 inches in diameter.
Hakurei: These Japanese turnips are small, sweet, and usually harvested when young. They can be eaten raw or cooked.
Golden Ball: With its yellow flesh and sweet flavor, this variety is perfect for those looking for something different.
Understanding your local climate and the ideal characteristics of each type will help you choose the best variety for your garden.
Turnips thrive in well-drained, fertile soil with a pH level between 6.0 and 7.0. A loamy soil enriched with organic matter provides the best conditions for healthy growth. Before planting, conduct a soil test to determine nutrient levels and pH balance. Amend your soil with compost or well-rotted manure to improve fertility.
Turnips prefer full sun, meaning at least 6-8 hours of direct sunlight per day. Ohio’s temperate climate is generally favorable for growing turnips; they prefer cooler temperatures of 50-65°F (10-18°C). They can tolerate light frosts, making them an excellent choice for fall gardens.
Consistent moisture is essential for successful turnip growth. The soil should remain evenly moist but not waterlogged. Overwatering can lead to root rot while underwatering may cause the roots to become woody or bitter. Water deeply once per week or more frequently during dry spells.
In Ohio, the best time to plant turnips depends on whether you choose to grow them as a spring or fall crop:
Spring Planting: Sow seeds outdoors about 2-4 weeks before the last expected frost date in your area (usually mid-April).
Fall Planting: For a late-season crop, plant seeds from mid-July to early August, allowing approximately 60 days before the first frost.
Prepare Your Garden Bed: Clear the area of weeds and debris. Loosen the soil down to at least 12 inches deep.
Sow Seeds: Plant seeds about ½ inch deep and spaced approximately 2 inches apart in rows that are 12-18 inches apart.
Thinning Seedlings: Once seedlings have emerged and reached about 2-3 inches tall, thin them out to prevent overcrowding. Aim for a spacing of about 4-6 inches between plants to allow ample room for root development.
Turnips benefit from additional nutrients during their growing season. Approximately two weeks after germination, apply a balanced fertilizer (10-10-10 or similar) following package directions for application rates. Avoid over-fertilizing as this can lead to lush greens but undersized roots.
Common pests that may affect turnip crops include aphids, flea beetles, and root maggots:
Aphids: These small insects feed on plant sap and can harm seedlings. Regularly inspect plants and use insecticidal soap if necessary.
Flea Beetles: These tiny jumping beetles create small holes in leaves. Use row covers or neem oil as preventive measures.
Root Maggots: To protect against root maggots, practice crop rotation and avoid planting turnips in the same spot more than once every three years.
Regular weeding is vital as it helps reduce competition for nutrients and moisture. Hand-pulling weeds or using mulching can effectively manage weed growth without harming your turnip plants.
Maintain consistent watering throughout the growing season; however, avoid getting foliage wet during watering sessions to reduce disease risk.
Harvesting turnips at the right time ensures optimal flavor and texture:
Timing: Depending on the variety planted, turnips are typically ready for harvest 30-70 days after sowing.
Indicators of Readiness: Check root size by gently digging around the base; mature turnips will reach about 2-4 inches in diameter.
Harvesting Technique: Use a garden fork or spade to lift roots carefully from the ground without damaging them. If harvesting greens too, cut leaves back leaving about an inch above the crown.
After harvesting your turnips:
Cleaning: Gently wash off soil but avoid soaking them in water.
Storage Conditions: Store unwashed turnips in a cool (32°F), dark place such as a basement or refrigerator crisper drawer for maximum shelf life (several weeks).
Greens Storage: If you’ve harvested greens too, rinse them off and store wrapped loosely in paper towels inside a plastic bag in the refrigerator.
