When to plant Turnips in New Zealand

The best time to plant turnips in New Zealand is during the cooler months, typically from late summer to early autumn (February to April). Turnips prefer cooler temperatures and can tolerate light frosts, making them ideal for planting in the transitional seasons. Planting in late summer allows the turnips to mature before the colder winter months, while planting in early autumn ensures a longer growing period before the arrival of winter. It’s important to note that turnips can also be planted in spring, but they may be more prone to bolting (going to seed) as temperatures rise.

When to harvest Turnips in New Zealand

Turnips can be harvested in New Zealand throughout the year, but the ideal time depends on the variety and your specific location within the country. Generally, turnips are ready to harvest when the roots have reached a desirable size, usually around 6-8 weeks after sowing the seeds.

For summer turnip varieties, such as “Tokyo Cross” or “Purple Top Milan,” it is best to sow the seeds in early spring and harvest them in late spring or early summer before the hot weather sets in. These turnips tend to bolt and become woody if left in the ground for too long during warm weather.

For winter turnip varieties, such as “Purple Top White Globe” or “Golden Ball,” sow the seeds in late summer or early autumn. These turnips can be left in the ground until late autumn or even winter, as they are more cold-tolerant and develop a sweeter flavor after exposure to frost.

To determine if turnips are ready for harvest, gently dig around the base of the plant and check the size of the roots. They should be firm and reach a desirable size, usually around 5-10 centimeters in diameter, depending on the variety. Harvest them by gently pulling or digging them out of the ground, being careful not to damage the roots.

Remember to regularly water and fertilize turnips during their growth period to ensure healthy and tasty roots.

Other considerations

When growing turnips in New Zealand, there are several important considerations to keep in mind:

  1. Climate: Turnips prefer cool weather and can tolerate light frosts. They grow best in regions with mild temperatures, such as the South Island and parts of the North Island. In warmer areas, it is advisable to grow turnips during the cooler months or in shaded areas to prevent bolting.
  2. Soil: Turnips thrive in well-draining soil with a pH level between 6.0 and 7.5. Before planting, prepare the soil by adding organic matter like compost or well-rotted manure to improve its fertility and drainage. Avoid heavy clay soils, as they can hinder root development.
  3. Sunlight: Turnips require full sun to grow and develop properly. Ensure they receive at least 6-8 hours of direct sunlight daily for optimal growth.
  4. Watering: Turnips need consistent moisture throughout their growing period. Keep the soil evenly moist, but not waterlogged, as excessive water can lead to rotting. Mulching around the plants can help retain moisture and suppress weed growth.
  5. Planting: Sow turnip seeds directly into the garden bed, as they do not transplant well. Plant the seeds at a depth of 1-2 centimeters and space them about 10-15 centimeters apart. Thin the seedlings to a final spacing of 20-30 centimeters to allow enough room for the roots to develop.
  6. Fertilization: Turnips are heavy feeders and benefit from regular fertilization. Prior to planting, incorporate a balanced fertilizer into the soil. Additionally, side-dress the plants with a nitrogen-rich fertilizer once they have established and again when they start forming bulbs.
  7. Pest and Disease Management: Turnips are generally resistant to pests and diseases. However, keep an eye out for common issues such as aphids, flea beetles, and clubroot. Regularly inspect the plants and take appropriate measures, such as using organic insecticides or practicing crop rotation, to prevent infestations.
  8. Harvesting: Turnips are ready for harvest when the roots reach a desirable size, usually around 6-8 weeks after sowing. Lift the turnips gently from the soil, taking care not to damage the roots. The greens can also be harvested and used in cooking or salads.

By considering these factors, you can successfully grow turnips in New Zealand and enjoy a bountiful harvest.
