There are not many restrictions on the planting time of shallots, and they can be planted almost all year round. So when to plant shallots? Let’s take a look with the editor below.

1. When to plant shallots?

1. Spring sowing

In northern regions, sowing is usually carried out in late March to early April. At this time, the temperature gradually rises, which is conducive to the growth of green onions. Due to the warm climate in the south, sowing can be carried out in late February to early March, about a month earlier than in the north.

2. Summer sowing

Shallots are usually sown in summer in May and June. However, it should be noted that the summer is hot and rainy, and although the growth rate of green onions is relatively fast, they are also susceptible to attacks by pests and diseases. Therefore, it is necessary to strengthen field management and harvest in time.

3. Autumn sowing

Autumn is the peak production season for shallots, and the sowing time is generally from August to September. The temperature in this season is suitable and the sunlight is sufficient, which is conducive to the growth and quality improvement of shallots. Shallots sown in the fall can usually be harvested in the winter or spring.

4. Winter sowing

In northern regions, winter sowing of shallots is usually done in November. Although the temperature is low in winter, the soil temperature can be maintained to promote the growth of green onions by covering it with insulating materials. In the southern regions, due to the warm winter climate, sowing can be carried out in December. The shallots sown at this time will be able to enter the growth period earlier in the spring of the following year and be available on the market earlier.

2. How to plant shallots

1. Planting

When planting shallots, you should choose a sunny, wind-sheltered place with fertile, loose soil and good drainage. The best soil pH is between 6.0 and 7.0. Before sowing, the seeds can be soaked in warm water for 2 to 3 hours to promote germination. After sowing, keep the soil moist and pay attention to removing weeds in the field in time.

2. Field management

Field management of shallots includes proper watering and fertilization. Since the roots of shallots are shallow, they should not be watered in large quantities and the soil should be kept moderately moist. When applying fertilizer, you can apply dilute human manure or urea, but be careful not to burn the roots.

3. Pest and disease control

In terms of pest and disease control, shallots may be invaded by pests such as aphids and onion thrips, as well as diseases such as downy mildew and leaf blight. Once pests and diseases are discovered, timely measures should be taken to prevent and control them.

The above is an introduction to when to plant shallots. The planting time of shallots varies depending on the region, climate and cultivation season. Farmers can choose the appropriate planting time according to the local temperature.
