How many days does it take for onions to germinate after sowing?

Scallions can be planted directly. It is best to plant plump and round seeds now. It is best to choose loose, water-retaining and fertilizer-retaining soil when planting. If you want green onions to germinate quickly after sowing, you can achieve this goal by soaking the seeds to accelerate germination. So how many days does it take for green onions to germinate after sowing? Let’s take a look with the editor below.

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

It usually takes 7 to 14 days for shallots to germinate after sowing. This time may be affected by environmental factors such as temperature and humidity. If the seeds are germinated in advance, such as soaking them in warm water for about 24 hours, then wrapping them in a wet towel and placing them in a warm place, the germination speed can be increased and the germination time can be shortened.

In addition, drying seeds before sowing can promote germination and shorten the time it takes to emerge from the soil. Suitable temperature and humidity conditions can lead to early germination, which usually takes about a week. Therefore, the time when shallots germinate and emerge from the soil will vary depending on the specific sowing method and environmental conditions.

2. Management of Scallion Sowing and Germination

1. Temperature management

Shallots need suitable temperature conditions to germinate. Generally speaking, the suitable temperature for shallot seeds to germinate is 13℃ to 20℃. If the temperature is too low, seed germination will be slow. If the temperature is too high, the seeds may rot. Therefore, after sowing, appropriate measures should be taken to maintain a suitable temperature according to local climatic conditions. For example, when sowing in spring and autumn, natural temperature conditions can be utilized; when sowing in summer, measures such as shading and cooling need to be taken.

2. Moisture management

Shallot seeds need plenty of water during the germination process. After sowing, water should be poured thoroughly in time to keep the soil moist. But be careful to avoid over-watering, which will cause waterlogging in the soil and affect the respiration and germination of seeds. You can use spraying to water, which can keep the soil moist without causing water accumulation. At the same time, the frequency and amount of watering should be determined according to the dryness and wetness of the soil and weather conditions.

3. Soil management

Scallions grow best in loose, fertile and well-drained soil. Before sowing, the soil should be deeply plowed and carefully cultivated to remove stones, weeds and other debris to make the soil loose. You can add appropriate amounts of organic fertilizers , such as decomposed compost, manure, etc., to improve soil fertility. Good soil structure can provide sufficient oxygen and water for shallot seeds, which is conducive to seed germination and emergence.

4. Lighting management

Scallions need plenty of light to grow. After sowing, make sure the shallot seeds receive enough light to promote their photosynthesis and growth. If there is insufficient light, it may cause problems such as slow growth of onions and yellowing of leaves. Therefore, during the planting process, choose a place with sufficient sunlight and no cover for sowing.

The above is an introduction to how many days it takes for green onions to germinate after sowing. Green onions germinate relatively quickly, generally three to five days after planting. They also grow very fast and can be eaten in about half a month if managed properly. If you want it to grow faster, you must pay attention to management methods after planting.
