Turnips (Brassica rapa) are one of the easiest and most rewarding root vegetables to grow. They are fast-maturing, nutritious, and can be harvested for both their delicious roots and leafy greens. Whether you are a beginner gardener or an experienced grower, understanding the optimal planting time and techniques is crucial for a successful turnip harvest.
Why Grow Turnips?
Turnips are packed with vitamins and minerals, including Vitamin C, fiber, and potassium. They are also highly versatile in cooking, making them a great addition to soups, stews, and salads. Plus, turnips are relatively low-maintenance and can thrive in various climates.
Best Time to Plant Turnips
Timing is everything when it comes to growing turnips. They are a cool-season crop, meaning they grow best in mild temperatures and can struggle in extreme heat.
- Spring Planting:
- Ideal for regions with mild winters.
- Sow seeds 2–4 weeks before the last expected frost in spring.
- This allows the plants to mature before the summer heat sets in.
- Fall Planting:
- Recommended for a sweeter, more flavorful harvest.
- Plant 6–8 weeks before the first expected frost in autumn.
- Fall-grown turnips tend to be tenderer and less bitter due to cooler temperatures.
Choosing the Right Variety
There are several varieties of turnips to choose from, depending on your preference:
- Purple Top White Globe – Classic variety with a mild flavor.
- Tokyo Cross – Fast-growing and perfect for early harvesting.
- Golden Ball – A yellow turnip with a sweet taste.
- Seven Top – Grown primarily for its leafy greens rather than its root.
Soil Preparation
Turnips thrive in loose, well-drained soil rich in organic matter. Here’s how to prepare your soil for planting:
- Loosen the soil up to 12 inches deep to encourage root growth.
- Remove large rocks or debris to prevent misshapen roots.
- Maintain a soil pH of 6.0–6.8 for best growth.
- Add compost or aged manure to enrich the soil with nutrients.
How to Plant Turnips
- Sowing Seeds:
- Directly sow seeds ½ inch deep and 1 inch apart in rows.
- Space rows 12–18 inches apart to give plants room to grow.
- Thinning Seedlings:
- Once seedlings sprout, thin them to 4–6 inches apart.
- Crowded plants will produce small or misshapen roots.
- Watering Requirements:
- Keep the soil evenly moist but avoid waterlogging.
- Water 1 inch per week, increasing during dry spells.
- Fertilization:
- Use a low-nitrogen fertilizer to promote root growth rather than excess foliage.
- Apply a balanced fertilizer (10-10-10) at planting time.
Caring for Turnip Plants
- Weeding: Regularly remove weeds to prevent competition for nutrients.
- Mulching: Add a layer of straw or grass clippings to retain moisture.
- Pest Control: Watch for aphids, flea beetles, and root maggots.
- Disease Prevention: Avoid planting turnips in the same spot every year to prevent soil-borne diseases.
When & How to Harvest Turnips
Turnips can be harvested at different stages depending on your preference:
- For Baby Turnips: Harvest 30–40 days after planting when they are about 1–2 inches in diameter.
- For Mature Turnips: Harvest 50–60 days after planting when they reach 2–3 inches in size.
- For Greens: Harvest the leaves when they are 4–6 inches tall, leaving some leaves to allow continued growth.
Storing Turnips
- Store turnips in the refrigerator for up to 2 weeks.
- For long-term storage, keep them in a cool, dark place like a root cellar.
- Blanch and freeze greens for later use.
Common Problems & Solutions
- Bitter or Woody Roots: Caused by old age or insufficient watering.
- Holes in Leaves: Usually due to flea beetles; use row covers for protection.
- Misshapen Roots: Happens when the soil is too compact or overcrowded.
