Onions are generally planted in September and harvested from the end of May to early June.

1. Planting time: Onion planting time can be selected between September and October. The most suitable time is recommended after mid-September. At this time, the weather in most areas is cool and the germination rate is relatively low. high. If planted in advance, the temperature will be higher and germination will be slower. Before sowing onion seeds, it is best to turn them over in the sun, soak them in warm water at 50 degrees Celsius, and rub them to remove the waxy layer, then you can grow the seedlings.

2. Harvesting time: Onions are generally harvested from the end of May to early June.

Turn the onions every 2 to 3 days. Next, dry in the sun until the leaves turn yellow.

Field management of onions

After onion seedlings grow stably, field management can be done well. During the growth period of the seedlings, there should be no lack of water, and the amount of watering should not be too much. The soil must be kept moist to avoid wilting of the seedlings and promote rapid growth of the roots of the seedlings. Prevent and control pests and diseases. Common onion diseases include rust, purple spot, downy mildew, etc.

It is necessary to control the temperature and light. Onions will grow better in an environment with scattered sunlight, and onions are long-day plants, so they must ensure about fourteen hours of light every day. When the onions germinate, At the same time, or during the growth period of seedlings, sufficient water is needed. The soil chosen for planting onions should be loose and fertile.
