Planting purple top turnips requires a specific approach to ensure healthy development and a bountiful harvest. This cool-season crop, prized for both its flavorful greens and nutritious root, adapts well to various climates when sown at the right time. Success depends on selecting a sunny location with well-draining soil that provides ample space for the root to expand. A firm understanding of the plant’s lifecycle helps gardeners coordinate planting dates with local weather patterns for optimal growth.
Choosing the Right Time to Plant
Timing is critical when you plant purple top turnips, as they thrive in cooler temperatures and can be damaged by intense summer heat. In northern regions, sow seeds directly into the garden as soon as the soil can be worked in early spring. A second successful planting occurs in late summer, allowing the crop to mature before the first hard frost, which actually enhances the sweetness of the roots. Consult local frost dates to determine the ideal window for both spring and fall seasons.
Preparing the Soil and Site
These turnips demand loose, friable soil to develop straight roots without forking or cracking. Prior to planting, clear the area of rocks, weeds, and debris that could impede root growth. Incorporate a generous amount of organic compost to improve fertility and drainage, creating a nutrient-rich environment. The ideal soil pH ranges between 6.0 and 7.0, slightly acidic to neutral, which allows the plant to absorb essential minerals efficiently.
Soil Amendment Tips
Add well-rotted manure or compost to boost organic matter.
Conduct a soil test to adjust pH if necessary.
Avoid heavy clay soils or use raised beds if drainage is poor.
Sowing the Seeds Correctly
To plant purple top turnips effectively, space the seeds about one inch apart and cover them with a thin layer of soil no deeper than half an inch. Press the soil gently to ensure good seed-to-soil contact, which is vital for germination. Rows should be spaced approximately 18 to 24 inches apart to allow adequate airflow and room for the roots to swell. Consistent moisture after sowing encourages rapid and uniform emergence.
Ongoing Care and Maintenance
Once the seedlings establish, thinning becomes necessary to prevent overcrowding and promote healthy root development. Remove weaker plants, leaving the strongest specimens spaced about four to six inches apart. Regular watering is essential to keep the soil consistently moist but not waterlogged, as fluctuating moisture levels can cause the roots to become woody or pithy. Weeding around the plants reduces competition for nutrients and light.
Harvesting for Best Quality
Harvesting purple top turnips at the right stage ensures the best flavor and texture for culinary use. The roots are typically ready for digging when they reach two to three inches in diameter, which usually occurs about 40 to 50 days after planting. Pull the greens gently to loosen the root before lifting it from the ground. For continuous harvest, pick the larger roots first and allow the smaller ones to continue growing.
Utilizing the Greens
The leafy tops of the purple top turnip are highly edible and nutritious, often used similarly to collard greens or mustard greens. Harvest the leaves when they are young and tender for the best taste, either raw in salads or cooked in soups and sautés. Leaving a few leaves on the plant allows it to continue photosynthesizing, which can support further regrowth if the roots are harvested later. This dual-purpose crop maximizes the yield from a single planting.
