How many days does it take for onion seeds to germinate?

As a common vegetable , onion not only has a unique taste but is also rich in nutrients and is deeply loved by people. In the process of onion cultivation, mastering some skills and management methods is crucial to improving the yield and quality of onions. So how many days does it take for onion seeds to germinate? Let’s take a look below.

1. How many days does it take for onion seeds to germinate?

The germination time of onion seeds is generally around 7 to 14 days. The specific time will be affected by many factors, including seed variety, environmental conditions and planting methods . Under suitable temperature conditions, the germination time of onion seeds is usually 7 to 10 days. The lower the temperature, the slower the germination speed. If germination treatment is carried out, the germination time can be shortened to 3 to 4 days. ‌

2. Green onion planting methods and key points

1. Soil selection: It is best to choose fertile, loose, well-drained, and deep soil for growing shallots. Alkaline soil may inhibit the healthy growth of shallots. Therefore, in terms of soil control, the pH value of the soil should be maintained between 6.0 and 7.0.

2. Process the seeds: There are many varieties of shallots. You can choose the variety according to the local climate and environment, requiring high yield, high stress resistance, good quality and high yield. Choose fresh seeds, mix the seeds in advance, and germinate them.

3. Sowing in the soil: Mix the seeds with fine sand and evenly spread them in the soil, keeping a spacing of 6-8 cm, cover with a thin layer of soil, and water them enough. Keep warm after sowing, keep the temperature at around 20 degrees, water regularly to keep it moist, and wait for the onions to germinate.

4. Watering: Scallions have a certain degree of drought resistance and do not need too much water after planting. If there is too much water, the roots of the shallots will rot, so we need to water them appropriately according to the drought resistance of the shallots, and the watering time can be controlled in the morning.

5. Fertilization: When planting shallots, base fertilizer should be applied, and phosphorus fertilizer needs to be supplemented during the seedling stage. Note that fertilizers containing nitrogen and phosphorus fertilizers need to be applied at different growth stages, but the ratios are different. Combined with some trace elements, it can promote vigorous growth of shallots.

6. Pest and disease control

During the growth process, shallots may encounter diseases such as onion blight and rust, as well as pests such as thrips and aphids. To prevent the occurrence of diseases and pests, disease-resistant and insect-resistant varieties can be selected, field management can be strengthened, and the disease resistance of shallots can be improved. Once pests and diseases are discovered, timely measures should be taken to prevent and control them, such as using biological control methods or chemical pesticides (but attention should be paid to the method and dosage of use).

7. Harvest and storage

When the shallots have grown to the right size, they are ready to harvest. Stop watering before harvesting to allow the soil to dry out slightly for easier digging. Dig up the shallots with a shovel or hoe, shake off the dirt, and tie them into bundles after drying them for a while. The place where shallots are stored should be ventilated, cool and dry to avoid mold and rot.

That’s it
