Daikon radishes also contain antioxidants, which can help protect cells from damage.
How to Grow Daikon Radishes
Growing daikon radishes is similar to growing traditional radish varieties, but they generally require more space and time to mature. Here are the steps involved:
1. Site Selection and Soil Preparation
Daikon radishes thrive in full sun to part shade and well-drained soil. Amend the soil with compost or manure to improve fertility and drainage.
2. Planting
In spring, plant daikon radish seeds as soon as the soil can be worked. Plant the seeds ¾ inch deep and 6 inches apart. Leave 3 feet between rows to allow for mature spread.
3. Watering and Fertilizing
Daikon radishes require regular watering, especially during hot, dry weather. Avoid overwatering, as this can lead to root rot. Fertilize the plants every few weeks with a balanced fertilizer.
4. Mulching and Weed Control
Mulch around the plants with a layer of straw or compost to conserve moisture, suppress weeds, and regulate soil temperature.
5. Thinning
Once the seedlings have emerged, thin them to the desired spacing. This will allow the remaining plants to grow to their full potential.
6. Harvesting
Daikon radishes are ready to harvest 60 to 70 days after planting. Harvest the radishes when they reach the desired size. To harvest, gently loosen the soil around the roots and pull the radishes straight up.
Tips for Success
- To ensure a continuous supply of daikon radishes, plant new seeds every 10 to 14 days.
- Daikon radishes can be planted in the winter in temperate climates or with the use of a cold frame or other protection.
- Companion planting with warm season crops such as peppers, tomatoes, or squash can be beneficial.
- Daikon radishes are susceptible to a few pests and diseases, including aphids, flea beetles, and root rot. Monitor the plants regularly and take appropriate control measures if necessary.
Conclusion
Growing daikon radishes is a fun and rewarding experience that can provide you with a delicious and nutritious vegetable. By following these tips, you can enjoy a bountiful harvest of daikon radishes all season long.
