How to Grow White Radish: Key Points on Planting Methods and Management Techniques

For white radish planting, choose sandy soil rich in humus, with a deep soil layer, good drainage, and loose, well-aerated texture; a pH of 5.3-7.0 is best. It requires sufficient light and prefers a mild, cool environment. The germination temperature is 20 to 25 degrees, and the leaf growth temperature is 15 to 20 degrees. Soil humidity is best at 65-80%, and air humidity at 80%-90%. The main focus is preventing and controlling mosaic disease, viral disease, soft rot, black heart disease, aphids, cabbage caterpillars, and other pests and diseases.

1. Soil: For growing white radish, it is best to choose sandy soil rich in humus, with a deep soil layer, good drainage, and loose, well-aerated texture; a pH of 5.3-7.0 is suitable. It is best to choose a plot that previously grew melons or legumes and has no pesticide residue.

2. Light: White radish requires sufficient light. With strong photosynthesis, more substances accumulate in the white radish, the fleshy root expands quickly, and the yield is high. If light is insufficient, carbohydrate accumulation is low, the fleshy root expands slowly, the yield is low, and the quality is poor.

3. Temperature: White radish is a semi-cold-tolerant vegetable and likes a mild, cool climate with a relatively large temperature difference. Seeds can germinate at 2 to 3 degrees Celsius, and the suitable germination temperature is 20 to 25 degrees Celsius. During the seedling stage, it can tolerate high temperatures of about 25 degrees Celsius and short periods of low temperature of minus 2 to 3 degrees Celsius. The suitable temperature for leaf growth is 15 to 20 degrees Celsius, and the most suitable soil temperature for fleshy root expansion is 13 to 18 degrees Celsius.

4. Water: White radish is not drought-tolerant. The suitable soil moisture is 65 to 80 percent of maximum water-holding capacity, and the suitable air humidity is 80 to 90 percent. Too much water means insufficient air in the soil, which affects the absorption and expansion of the fleshy root, and the skin also becomes rough. Uneven water supply can also easily cause the fleshy root to crack.

5. Pests and diseases: The main diseases of white radish include mosaic disease, viral disease, soft rot, and black heart disease, and the main pests include aphids, cabbage caterpillars, and others. The key to disease prevention and control is to strengthen cultivation management, keep the plants robust, enhance disease resistance, and combine chemical control for integrated management.

6. Harvest: When the leaf color turns yellow and fades, the fleshy root has fully expanded and the base is round and blunt, meaning it has reached commercial standards, and it can then be harvested.

White radish is also called little ginseng. It is a very popular food on the market, and growing and managing white radish is also relatively simple. It can be grown in both the south and the north.
