How many days does it take for green onions to sprout?

Scallions are a common vegetable , especially widely cultivated and eaten in various parts of China. Scallions may be called differently in different regions, such as chives, shallots, alliums, etc. So how many days does it take for green onions to sprout? Let’s take a look with the editor below.

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

The emergence time of shallots is affected by many factors, including seed quality, soil conditions, temperature and humidity. Generally speaking, if conditions are suitable, it takes about 7 to 14 days for shallot seeds to germinate from sowing.

The suitable temperature for germination of shallot seeds is 15 to 25℃. Within this temperature range, seeds can absorb water and oxygen more quickly, and their metabolic activity is more vigorous, which is conducive to the germination and growth of the embryo. For example, in an environment of around 20°C, shallot seeds may germinate in about 6 to 7 days.

When the temperature is below 10℃, the physiological activity of seeds is inhibited, the germination speed will be significantly slowed down, and it may take 10 days or even longer for seedlings to emerge. When the temperature is higher than 30℃, the seeds may enter a dormant state, resulting in a lower germination rate or even no germination.

2. How to grow shallots

1. Seed selection

Choose shallot varieties that are suitable for local climate and soil conditions, such as common shallots, chives or all-season chives. If you are sowing, you should choose seeds with full grains and no diseases or insect pests. If you are purchasing seedlings, you should choose healthy seedlings with well-developed root systems and green leaves.

2. Prepare the soil

Scallions do not have high requirements for soil, but in order to make them grow better, you should choose fertile, loose and well-drained soil. You can mix leaf mold, garden soil and river sand in a certain proportion to make a culture soil suitable for growing green onions. Before planting, it is best to disinfect the soil to kill pathogens and insect eggs in the soil.

3. Planting seeds

Sowing is done in spring or autumn when the moderate temperature is conducive to seed germination and plant growth. Sprinkle the seeds evenly on the soil surface, and then cover with a thin layer of soil, the thickness of which is about 1 to 2 times the diameter of the seeds. Water lightly after planting to keep the soil moist.

4. Transplantation

First dig a planting hole in the soil, then place the seedling in the hole, straighten it and fill it with soil. After transplanting, water the plants sufficiently to allow the roots to fully contact the soil. The suitable temperature for growing shallots is 15~25℃. When it is cold in winter, pay attention to keep warm to prevent the plants from freezing. You can cover the plants with a layer of straw or plastic film to increase the temperature.

The above is an introduction to how many days it will take for shallots to germinate. It usually takes 5 to 10 days from sowing to germination of shallots. Shallot seeds germinate fastest at temperatures between 15°C and 25°C. If the temperature is too low, the germination rate will be slowed down, and if the temperature is too high, it may affect the germination rate of the seeds.
