Turnips, those humble root vegetables, are a staple in many gardens and kitchens. But if you’re a new gardener or just curious about the process, you might be wondering: how long does it really take for turnips to be ready? The answer, while seemingly simple, can vary depending on several factors. Let’s delve into the world of turnips and explore the timeline from seed to table.
Understanding Turnip Growth Cycles
The time it takes for turnips to mature is relatively short compared to other root vegetables like carrots or parsnips. Most turnip varieties are considered fast-growing, making them a rewarding crop for both beginners and experienced gardeners. However, understanding the different stages of growth is crucial for successful cultivation.
The Germination Phase
The first step in the turnip journey is germination. This is when the seed sprouts and begins to grow. Typically, turnip seeds germinate within 5 to 10 days, provided the soil temperature is between 60°F and 70°F. Consistent moisture is key during this phase. Ensure the soil remains damp, but not waterlogged, to encourage successful germination.
Soil temperature plays a vital role. If the soil is too cold, germination can be delayed or even prevented. Conversely, excessively high temperatures can also inhibit germination.
Vegetative Growth
After germination, the turnip plant enters a phase of vegetative growth. This is when the plant focuses on developing its leaves and root. During this stage, the plant requires adequate sunlight, water, and nutrients.
The leaves are responsible for photosynthesis, which provides the energy the plant needs to grow. Thinning seedlings is important during this phase to prevent overcrowding and ensure each plant has enough space to develop. Proper spacing allows for better air circulation, reducing the risk of disease.
Root Development
The most crucial part of the turnip’s growth cycle is root development. This is when the bulb, the edible part of the turnip, begins to form and expand. The size and quality of the root are greatly influenced by soil conditions, watering practices, and nutrient availability.
Well-drained soil is essential for healthy root development. Heavy, compacted soil can restrict growth and lead to misshapen or small turnips. Amending the soil with compost or other organic matter can improve drainage and provide essential nutrients.
Factors Influencing Turnip Maturity Time
While most turnip varieties mature in a relatively short timeframe, several factors can influence the actual time it takes for your turnips to be ready for harvest. Understanding these factors can help you optimize your growing conditions and ensure a successful crop.
Turnip Variety
Different turnip varieties have different maturity times. Some varieties are specifically bred for rapid growth, while others take longer to mature. Popular varieties like ‘Purple Top White Globe’ and ‘Tokyo Cross’ are known for their relatively quick maturity, typically around 50 to 60 days. Other varieties might take closer to 70 or even 80 days. Always check the seed packet for the specific maturity time of the variety you are growing.
Climate and Weather Conditions
Climate and weather conditions play a significant role in turnip growth. Turnips thrive in cool weather and are often grown as a spring or fall crop. Hot weather can cause them to become bitter and woody. The optimal temperature range for turnip growth is between 60°F and 70°F.
Extreme temperatures, whether hot or cold, can slow down growth and affect the quality of the turnips. Frost can damage the leaves, while excessive heat can lead to bolting (premature flowering), which can make the roots tough and unpalatable.
Soil Quality and Nutrients
The quality of your soil directly impacts the growth and development of turnips. Turnips prefer well-drained, fertile soil with a slightly acidic pH (around 6.0 to 6.5).
Soil that is lacking in essential nutrients can lead to stunted growth and poor root development. Adding compost or other organic matter to the soil can improve its fertility and drainage. A balanced fertilizer, such as 10-10-10, can also be beneficial, but avoid over-fertilizing, as this can lead to excessive leaf growth at the expense of root development.
Watering Practices
Consistent and adequate watering is crucial for turnip growth. Turnips need about 1 inch of water per week, either from rainfall or irrigation. Irregular watering can lead to stress, which can affect the size and quality of the roots.
Avoid overwatering, as this can lead to root rot and other fungal diseases. Use a soaker hose or drip irrigation to water deeply and evenly, focusing on the root zone.
Pest and Disease Management
Pests and diseases can significantly impact turnip growth and delay maturity. Common turnip pests include aphids, flea beetles, and root maggots. Diseases such as clubroot and downy mildew can also affect turnip crops.
Regularly inspect your plants for signs of pests or diseases. Implement preventative measures, such as crop rotation and using row covers, to minimize the risk of infestation or infection. If necessary, use organic pest control methods or disease-resistant varieties.
A Realistic Turnip Growth Timeline
So, putting it all together, what’s a realistic timeline for growing turnips? Let’s break it down into stages:
- Days 1-10: Germination. Seeds sprout and seedlings emerge.
- Days 10-30: Vegetative growth. The plant develops its leaves and begins to establish its root system.
- Days 30-50: Root development. The turnip bulb starts to form and expand.
- Days 50-70 (or longer, depending on variety): Maturity. The turnips reach their optimal size and are ready for harvest.
This is a general guideline, and the actual timeline may vary depending on the factors mentioned earlier. Regularly monitor your plants and adjust your growing practices as needed.
Harvesting Your Turnips at the Right Time
Knowing when to harvest your turnips is crucial for ensuring the best flavor and texture. Harvesting too early can result in small, underdeveloped roots, while harvesting too late can lead to tough, woody roots.
Most turnip varieties are ready for harvest when the roots are 2-3 inches in diameter. Check the seed packet for specific size recommendations. You can also gently dig around the base of a plant to check the size of the root.
To harvest, loosen the soil around the turnip with a garden fork or trowel. Gently pull the turnip from the ground, being careful not to damage the root. Cut off the greens, leaving about 1 inch of stem.
Storing Your Turnips for Later Use
Proper storage can extend the shelf life of your turnips and allow you to enjoy them for weeks or even months after harvest.
Store turnips in a cool, dark, and humid place, such as a root cellar or refrigerator. Remove the greens before storing, as they can draw moisture from the roots. Place the turnips in a plastic bag or container to prevent them from drying out.
Turnips can also be frozen for longer-term storage. Blanch the turnips in boiling water for a few minutes, then transfer them to an ice bath to stop the cooking process. Drain the turnips and pack them into freezer bags or containers.
Troubleshooting Common Turnip Growing Problems
Even with the best care, you may encounter some challenges when growing turnips. Here are some common problems and how to address them:
- Poor germination: Ensure the soil is warm enough and consistently moist. Use fresh seeds and sow them at the correct depth.
- Stunted growth: Check the soil for nutrient deficiencies. Amend the soil with compost or fertilizer.
- Pest infestations: Regularly inspect plants and use organic pest control methods.
- Disease problems: Choose disease-resistant varieties and practice crop rotation.
- Bitter or woody roots: Harvest turnips before they become too large. Ensure consistent watering and avoid extreme temperatures.
By addressing these problems promptly and effectively, you can minimize their impact on your turnip crop.
Enjoying Your Homegrown Turnips
Once you’ve harvested your turnips, it’s time to enjoy the fruits (or rather, roots) of your labor! Turnips are a versatile vegetable that can be used in a variety of dishes.
They can be eaten raw, roasted, mashed, boiled, or added to soups and stews. The greens are also edible and can be cooked like spinach or other leafy greens.
Experiment with different recipes and find your favorite ways to enjoy your homegrown turnips.

Growing turnips can be a rewarding experience, providing you with a delicious and nutritious vegetable in a relatively short amount of time. By understanding the factors that influence turnip maturity, you can optimize your growing conditions and ensure a successful harvest. From germination to harvest, paying attention to the specific needs of your turnip plants will lead to a bountiful crop of these delightful root vegetables. Happy gardening!
How long after planting can I expect to harvest turnips?
Turnip varieties vary, but generally, you can expect to harvest turnip roots in about 50 to 60 days after planting. For turnip greens, you can start harvesting them much earlier, often within 30 to 40 days. Remember to check your specific seed packet or plant tag for the exact maturity date for your chosen variety.
The time to harvest also depends on the growing conditions. Ideal conditions such as well-drained soil, sufficient sunlight, and adequate watering will promote faster growth and earlier harvest times. Unfavorable conditions can delay maturity, so ensuring optimal care is crucial for a timely harvest.
What are the signs that my turnip roots are ready to be harvested?
The best way to determine when your turnip roots are ready is to check their size. Most varieties are best harvested when the roots are between 2 and 3 inches in diameter. Larger roots can become tough and woody, so it’s better to err on the side of harvesting them slightly earlier.
You can gently loosen the soil around the base of a turnip and check its size without fully pulling it out. Also, observe the above-ground portion; if the part of the root showing above the soil appears smooth and firm, it is likely ready. Avoid waiting too long, as over-mature turnips can lose their sweetness and become bitter.
Can I harvest turnip greens before the roots are ready?
Absolutely! Turnip greens are a delicious and nutritious leafy vegetable. You can start harvesting them once they are a few inches tall, usually around 30 to 40 days after planting. Harvesting the outer leaves allows the inner leaves and the root to continue growing.
Be careful not to harvest more than a third of the leaves at any one time, as this can weaken the plant and affect root development. Consistent, moderate harvesting of the leaves ensures a continuous supply of greens while still allowing for a good root harvest later on.
Does the time of year I plant turnips affect how long they take to mature?
Yes, the time of year significantly impacts the maturation time of turnips. Turnips are a cool-season crop, thriving in temperatures between 60°F and 65°F. Planting in the spring for a summer harvest or in late summer for a fall/winter harvest is ideal.
Planting outside these ideal temperature ranges can affect growth. High temperatures can cause turnips to bolt (go to seed), resulting in bitter roots and reduced leaf quality. Very cold temperatures can slow growth. Planting at the appropriate time of year allows for optimal growth and a quicker harvest.
What factors besides temperature can affect how quickly turnips grow?
Several factors can affect turnip growth besides temperature. Soil quality is crucial. Turnips prefer well-drained, fertile soil with a pH between 6.0 and 6.8. Proper watering is also essential; consistent moisture promotes healthy growth.
Sunlight is another key factor. Turnips need at least 6 hours of sunlight per day to thrive. Nutrient availability also plays a role; a balanced fertilizer can help ensure optimal growth. Finally, pests and diseases can slow growth or damage the plants, so proactive pest and disease management is important.
How do I know if my turnips are bolting, and what does it mean for harvest time?
Bolting is when a plant prematurely flowers and sets seed, typically due to stress such as heat or lack of water. You’ll notice a tall flower stalk emerging from the center of the turnip plant. If your turnips start to bolt, it signifies that the roots are likely becoming tough and bitter.
Once turnips bolt, the roots are generally not worth harvesting. The plant is diverting energy into seed production, which compromises the quality of the root. It’s best to harvest any remaining good-quality roots immediately and consider planting a new crop of turnips if the bolting is widespread.
Can I store turnips after harvesting them, and for how long?
Yes, turnips can be stored after harvest, especially the roots. Remove the greens (leaving about an inch of stem) and gently brush off any excess soil. Store the turnip roots in a cool, humid place like a refrigerator crisper drawer or a root cellar.
Under the right conditions, turnips can last for several months. The cooler and more humid the storage environment, the longer they will keep. Turnip greens, however, are best used fresh and will only last for a few days in the refrigerator.
