How many days does it take for onions to sprout?

Scallions are a common root vegetable in people’s home cooking. They can be added to prepared dishes to add flavor, and the taste is delicious, and they are loved by the public. Many people want to grow some onions at home, so how many days does it take for onions to sprout? Let’s take a look below.

1. How many days does it take for onions to sprout?

Onion seeds usually germinate 7 to 14 days after sowing. The main factors affecting the germination of onion seeds are soil moisture, temperature and light. ‌

During the planting process, reasonable management and suitable environmental conditions can promote the rapid germination of onion seeds. For example, seeds can be dried before sowing, which can not only shorten the germination time, but also eliminate some pests and pathogens, enhance the vitality of seeds and improve the germination rate.

2. High-yield planting technology of shallots

1. Planting time

The suitable temperature for shallots is a warm to cool climate, with the best temperature being around 15-25 degrees. In North China, they are generally planted in spring and autumn. Spring is generally around the Qingming Festival, and autumn is best planted around the autumnal equinox. Other regions decide whether to sow in spring or autumn based on the climate. In addition, shallots are cold-resistant and can survive the winter, so there is no need to worry about management in winter.

2. Growth temperature

The temperature for shallots should be determined according to their growth habits. Since shallots prefer cool weather, the suitable temperature is basically around 12 to 22 degrees. The temperature should not be too high, because too high a temperature will cause the shallots to grow slowly. Therefore, some farmers have reported that their shallots do not grow or grow slowly, and a small part of the reason is the temperature. Pay attention to shading in the summer.

3. Watering tips

During the growth period of shallots, appropriate watering is sufficient. The amount of watering should not be too large. Excessive watering will cause water accumulation, which will lead to root rot of the shallots. Therefore, appropriate watering should be carried out according to the characteristics of shallots that they are drought-resistant but not water-resistant. When the soil is dry, appropriate amount of watering will be sufficient. Large-scale irrigation is not recommended.

4. Soil selection

The growth of shallots is not demanding on the soil. For planting shallots, you only need to choose fertile, loose, well-drained, and deep soil. For soil with too high alkalinity, the acid and base must be neutralized before planting, because alkaline soil will affect the growth and development of shallots. The pH value of the soil is maintained at 6-7, which is most suitable for the growth of shallots.

5. Fertilization management

Phosphorus fertilizer should be supplemented in time during the seedling stage, and nitrogen and potassium fertilizers should be supplemented mainly during the growth period, and then trace nutrients should be supplemented appropriately. In different growth periods, nitrogen, phosphorus and potassium fertilizers should be used as the main fertilizers, and then combined with trace elements for fertilization, which is more conducive to the growth and yield of green onions.

6. Harvest management

Scallions are a kind of vegetable that can be harvested like leeks . Scallions can be harvested once every month or so. It should be noted here that you should not harvest them every 10 days or so just because they can be harvested. Too short a time will cause the scallions to not have nutritional roots. It is best to harvest them once a month or so.

Scallions are a sun-loving vegetable. The more sunlight and the drier the environment, the stronger the flavor of the scallions. Conversely, less sunlight and more water will make the scallions taste lighter and less spicy. Therefore, when the scallions are about to be harvested, you can reduce the sunlight and retain the moisture. This way, the scallions will be more tender and have a longer shelf life.
