Turnips, scientifically known as Brassica rapa, are a cool-weather root vegetable that thrives in both home gardens and larger plots. Known for their versatility, turnips can be eaten raw, roasted, boiled, or used in soups and stews. Their mild, slightly peppery flavor is complemented by their crisp texture when harvested at the right time.
Whether you’re a beginner gardener or an experienced horticulturist, growing turnips from seed to harvest is a rewarding and relatively easy process. In this guide, we’ll walk you through each step—covering everything from preparing your soil to harvesting your turnips. With proper care and attention, you’ll be able to enjoy a bountiful turnip harvest in just a few months.
Why Grow Turnips?
Before diving into the specifics of growing turnips, let’s consider why they’re worth cultivating in your garden:
- Fast Growing: Turnips grow quickly, with the roots maturing in 2-3 months.
- Cold-Tolerant: They perform well in cool weather, making them an excellent choice for early spring or late fall gardens.
- Easy to Grow: Turnips are low-maintenance and can be grown in a variety of soil types.
- Nutrient-Rich: Turnips are packed with vitamins C and K, fiber, and antioxidants, offering numerous health benefits.
- Dual Harvest: You can harvest both the roots and the leafy greens, making turnips a versatile addition to your garden.
Now, let’s break down the process of growing turnips from seed to harvest.
1. Choosing the Right Location for Growing Turnips
Turnips prefer a sunny location, though they can tolerate light shade. Select a spot that receives at least 4 to 6 hours of sunlight daily. While turnips can grow in a variety of soils, they do best in loose, well-drained soil that is rich in organic matter. Sandy loam or loamy soils are ideal, as they allow turnip roots to grow freely without becoming stunted or misshapen.
Tip: If your soil is heavy clay or compacted, consider amending it with compost or organic matter to improve drainage and structure.
2. Preparing the Soil for Planting Turnips
Before sowing turnip seeds, it’s essential to prepare your soil properly. Start by clearing the area of weeds and debris. Turnips do best in neutral to slightly alkaline soil with a pH range of 6.0 to 7.5. If you’re unsure about your soil’s pH, a simple soil test can help determine whether amendments are necessary.
Next, loosen the soil to a depth of at least 6 inches. You can use a shovel, garden fork, or tiller to break up compacted soil. Once the soil is loosened, mix in 2 to 4 inches of well-aged compost or organic matter to boost fertility and improve soil structure. Organic matter will help retain moisture, provide nutrients, and promote healthy root development.
3. Planting Turnip Seeds
Turnips are typically sown directly into the soil, as they don’t transplant well. The best time to plant turnips is in early spring (as soon as the soil is workable) or late summer for a fall harvest. Ensure the soil temperature is between 50°F and 75°F for optimal germination. If planting in spring, try to sow seeds about 2 weeks before the last frost date. For a fall crop, plant seeds in mid-to-late summer, about 10 weeks before the first expected frost.
How to Plant Turnip Seeds:
- Spacing: Create shallow furrows about 1/2 inch deep and 1 inch apart. Space rows about 12 to 18 inches apart to give the plants room to grow.
- Sow Seeds: Drop 2-3 seeds into each furrow, then cover them lightly with soil.
- Watering: Gently water the area after planting to moisten the soil. Keep the soil consistently moist during the germination period.
Tip: Turnip seeds will germinate in 4-10 days, depending on soil temperature and moisture levels.
4. Thinning Seedlings for Healthy Growth
Once your turnip seeds have germinated, you’ll notice several small seedlings emerging from the soil. At this stage, it’s important to thin them out to prevent overcrowding, which can lead to small, underdeveloped roots.
How to Thin Turnip Seedlings:
- Once the seedlings have grown to about 2-3 inches tall, carefully thin them out by removing the weaker seedlings. Aim for a spacing of about 3-4 inches between each plant. Use a pair of scissors or your fingers to gently pinch off the unwanted seedlings at the soil level.
- Don’t pull the seedlings out of the ground, as this may disturb the roots of the remaining plants.
Tip: You can eat the thinned seedlings as young greens, adding a fresh, mild flavor to salads and other dishes.
5. Caring for Turnips During the Growing Season
Turnips are relatively low-maintenance, but there are a few key factors to monitor throughout their growth:
- Watering: Keep the soil consistently moist, especially during dry periods. Turnips prefer moist, but not soggy, soil. Aim for about 1 inch of water per week, either through rainfall or irrigation.
- Fertilizing: Turnips benefit from a light feeding of balanced fertilizer during the growing season. Apply a slow-release fertilizer or organic compost in the spring, and side-dress with additional fertilizer as needed.
- Weeding: Keep the area around your turnips weed-free to prevent competition for nutrients. Hand-pull weeds or use a hoe to carefully remove them, taking care not to disturb the turnip roots.
- Mulching: Apply a 1-2 inch layer of mulch around the plants to conserve moisture, suppress weeds, and maintain even soil temperatures.
Tip: Mulch can also help keep the soil cool, which is important for turnips, as they tend to bolt (flower and go to seed) in hot weather.
6. Harvesting Turnips
Turnips are ready to harvest when their roots reach about 2-3 inches in diameter, typically 50-70 days after planting, depending on the variety and growing conditions. However, turnips can be harvested at any size—smaller turnips tend to be milder and more tender, while larger turnips have a stronger flavor and firmer texture.
How to Harvest Turnips:
- Check the Size: Gently dig around the base of the turnip to check the size of the root. If it’s large enough, it’s ready for harvest.
- Lift the Root: Use a garden fork or shovel to carefully lift the turnips out of the ground. Be gentle to avoid damaging the root.
- Cut the Greens: If you plan to eat the greens, cut them off about 1-2 inches above the root. Turnip greens are edible and can be sautéed, used in soups, or added to salads.
Tip: For continuous harvest, plant turnip seeds in succession every few weeks to ensure a steady supply of roots and greens.
7. Storing and Using Turnips
Once harvested, turnips can be stored in several ways:
- Fresh Storage: Store turnips in a cool, dark place, such as a root cellar, for up to 1-2 months. If you don’t have a root cellar, refrigerate them in a plastic bag to extend shelf life.
- Freezing: Turnips can be frozen for long-term storage. Peel and blanch them in boiling water for 2-3 minutes, then cool them in ice water before freezing.
Turnips are versatile in the kitchen. They can be eaten raw, roasted, boiled, mashed, or incorporated into soups and stews. Their mild, earthy flavor pairs well with a variety of other vegetables and herbs.
