How and when to plant onions in the north

Suitable planting time for northern onions

The best time to plant onions in the north is from September to October. At this time, the climate in the north is relatively cool, which allows the onions to take root and sprout quickly, and the survival rate is higher. If the planting time is not right, it will be difficult for the onions to germinate.

Methods and key points of planting onions in the north

1. Northern onions prefer to grow in loose, fertile and well-ventilated soil. Before planting, you need to select a site and then prepare the land to make the soil loose and breathable. You also need to add base fertilizer to the soil. After preparation, you can plant it.

2. Water the soil before planting, then spread the onion seeds evenly on the soil and cover them with a thin layer of soil. Keep the soil moist. After a period of time, the onions will germinate and grow. You can also soak the seeds and sow them after germination, which can increase the germination rate.

Points to note for daily management of onions

After the onions are planted, they will enter the seedling growth period in about 20 days. Be careful not to water them in large quantities. Excessive watering will cause the soil temperature to drop, slowing down the growth of the onions.

It is recommended to water in small amounts and multiple times. Do not let the onion seedlings wilt. The ground can be semi-dry. Each acre of onion field requires 12 to 15 kg of nitrogen fertilizer, 8 to 10 kg of phosphorus fertilizer, and 10 to 12 kg of potassium fertilizer, so that the onions can grow better.
