Turnips are a versatile and nutritious root vegetable that thrive in cooler climates, making them an excellent choice for gardeners in New Hampshire. With their rich flavor and ease of cultivation, turnips can be a rewarding addition to your home garden. This article will explore the essential steps needed to successfully grow turnips in New Hampshire, covering everything from soil preparation to harvesting.
Turnips (Brassica rapa) belong to the Brassicaceae family, which also includes cabbage, kale, and broccoli. They are biennial plants grown as annuals for their edible roots and greens. Turnips are typically white or yellow-fleshed and can be enjoyed raw in salads, roasted, or mashed like potatoes. Furthermore, both the roots and the greens are packed with vitamins and minerals, making turnips a healthy choice.
While there are several varieties of turnips available, some may be better suited to New Hampshire’s climate than others. Here are a few recommended varieties:
Selecting the right variety will ensure a bountiful harvest based on your culinary preferences.
Turnips thrive in well-drained, fertile soil with a pH range of 6.0 to 7.5. Here’s how you can prepare your soil:
Testing Soil: Before planting, conduct a soil test to determine its pH level and nutrient content. Local agricultural extensions often provide testing services.
Soil Amendment: Based on the soil test results, amend your soil with organic matter such as compost or well-rotted manure to improve fertility and drainage.
Tilling: Till the soil to a depth of at least 12 inches to break up compacted layers and promote strong root development.
Leveling: Rake the soil surface to remove debris, rocks, and clumps while leveling it out for even planting.
Turnips can be sown directly in the garden or started indoors and later transplanted. Here is the process for sowing seeds directly:
Timing: In New Hampshire, turnips can be planted in early spring (April) or late summer (August) for a fall harvest. The cool weather encourages sweetening of the roots.
Spacing: Plant seeds ½ inch deep in rows spaced about 12-18 inches apart. Thin seedlings to about 4-6 inches apart once they have developed their first true leaves.
Watering: Water the seeds thoroughly after planting to help them germinate but avoid waterlogging the soil.
Proper care throughout the growing season is crucial for a successful turnip harvest.
Turnips require consistent moisture, especially during dry spells. Aim for about an inch of water per week, either through rainfall or supplemental irrigation. Water early in the day to minimize evaporation and prevent fungal diseases.
Weeds compete with turnips for nutrients and moisture; therefore, regular weeding is essential. Mulching around plants with straw or wood chips can suppress weed growth while retaining soil moisture.
While turnips can grow well in nutrient-rich soil, additional fertilization may be beneficial:
Nitrogen-Rich Fertilizer: Apply a balanced fertilizer that’s higher in nitrogen when plants are young to promote leaf growth.
Additional Nutrients: As roots begin to develop, supplement with phosphorus and potassium to enhance root health.
Turnips are susceptible to various pests and diseases. Here are some common issues in New Hampshire gardens:
Cabbage Worms: These pests can damage leaves significantly; handpicking or using row covers can help prevent infestations.
Aphids: These tiny insects can sap plant strength; insecticidal soap or neem oil can manage their populations effectively.
Downy Mildew: A fungal disease that thrives in humid conditions; ensure good air circulation by proper spacing between plants.
Root Rot: Caused by over-watering or poorly drained soil; ensure adequate drainage by avoiding heavy mulch around roots.
Regularly inspect your plants for signs of pests or diseases early on so you can take swift action before they affect your harvest significantly.
Knowing when to harvest turnips is key for optimal flavor and texture:
Timing: Generally, turnips are ready for harvest approximately 30-60 days after sowing, depending on the variety.
Signs of Readiness: The roots should reach about 2-3 inches in diameter for optimal taste; larger roots may become woody or bitter.
How to Harvest: Carefully use a garden fork or spade to loosen soil around the base of the turnip before gently pulling it from the ground—avoid damaging the root.
Post-Harvest Handling: Remove any excess dirt gently without bruising the root; store harvested turnips in a cool, dark place if not consumed immediately.
Turnips can last several weeks when stored properly:
Temperature: Ideally store them at temperatures between 32°F – 40°F (0°C – 4°C) with high humidity.
Container: Use breathable containers like burlap sacks or paper bags lined with moist paper towels to maintain humidity levels without causing rot.
Check Regularly: Monitor stored turnips regularly for signs of rot or spoilage; remove any affected roots promptly.
