How many days does the white radish grow?

The germination period is from the germination of white radish seeds to the unfolding of the first true leaf. The first true leaf spreads to 5-6 leaves and the main root breaks through the belly, which is the seedling stage. From the "breaking through the belly" stage, the fleshy roots on the shoulders swell significantly, which is the peak growth period of leaves. The peak growth period of fleshy roots is from shoulder exposure to harvest. It can be harvested and put on the market at this stage.

White radish growing period

The growing period of white radish is 80-100 days, and it can be planted all year round. Autumn and winter radishes are generally cultivated in the north, sown in early autumn or summer, and can be harvested before the beginning of winter. Winter and spring radishes are planted in the south, cultivated in late autumn and early winter, and harvested in February to March after wintering.

White radish growing conditions

White radish prefers a mild and cool environment and has a certain degree of cold resistance. The suitable temperature for germination is 20-25 degrees, the suitable growth temperature for leaves is around 20 degrees, and the suitable growth temperature for roots is between 13 and 18 degrees. It requires sufficient light so that the fleshy roots will swell quickly and the yield will be high.

White radish does not have high requirements for soil, but the best soil is deep, humus-rich, well-drained, loose and breathable sandy soil. The pH value of the soil should be 5.3-7. If the soil is too sticky, it will lead to a decrease in yield.

Management of white radish during growth period

1. Watering

Watering white radish frequently during the seedling stage can lower the ground temperature. During the rosette stage, the above-ground leaves grow vigorously and the fleshy roots just begin to grow. During this period, you can control the water appropriately and wait until the ground is slightly dry to water. When the fleshy roots reach the growth and expansion stage, the demand for water increases. Watering should be even, and it should not be dry and wet at the same time.

2. Fertilization

For white radish, topdressing mainly consists of urea from the time of seedling establishment to the growth period of fleshy roots. When it enters the rosette stage, topdressing mainly consists of nitrogen and potassium. When the fleshy roots are expanding, compound fertilizer can be applied while spraying potassium dihydrogen phosphate and borax on the leaves to promote the growth of fleshy roots and improve the quality of radish.

3. Pest control

Generally, there are few diseases during the growth period of white radish, but pests have a greater impact, such as cabbage borer, flea beetle, cabbage looper, etc., which can also spread pathogens. During field management, pesticides should be sprayed in time for prevention and control, such as emamectin benzoate, indoxacarb, and highly effective chlorfenapyr, etc., and prevention and control should be carried out as early as possible in the seedling stage.
