How to Plant Black Radish
Black radish is a highly nutritious and cold-resistant vegetable that has gained popularity in recent years due to its unique taste and medicinal properties. In this article, you’ll learn the step-by-step method of planting black radish—from sowing to harvest.
Best Time to Plant Black Radish
The best time to plant black radish in Iran is in early autumn (from late August to late September). This plant prefers cool weather. If planted in hot conditions, its growth will be weak, and the taste will become too sharp.
Ideal Soil Conditions for Growing Black Radish
The soil should be light, soft, and well-drained.
The best option is sandy-loam soil, which allows the root to grow straight and healthy.
Before planting, till the soil to a depth of 30 cm and mix in well-rotted manure or compost.
How to Sow Black Radish Seeds
To achieve a high-quality yield, follow these steps:
Sow the seeds in rows.
Planting depth: about 1 to 1.5 cm
Spacing between plants: 10 to 15 cm
Spacing between rows: 30 to 40 cm
After planting, gently press the soil and water lightly.
How to Water Black Radish
During the first week, water lightly on a daily basis.
After the seeds sprout, watering every 3 to 5 days is sufficient.
Note: Overwatering can cause the roots to crack and reduce the quality of the crop.
Thinning and Weeding
When the plants develop 3 to 4 true leaves, remove the closely spaced seedlings (thinning).
Weed the area regularly to prevent competition for water and nutrients.
Harvest Time for Black Radish
Black radish is usually ready to harvest 60 to 80 days after sowing.When the root reaches a diameter of 5 to 10 cm, it’s time to harvest.
Use a hand tool or pull by hand for harvesting.
If left in the ground too long, the roots will become tough and overly spicy.
Additional Tips for Growing Black Radish
