How to Grow Scallions for High Yield? A Detailed Guide to Practical Growing Techniques

Scallions are a common root vegetable in people's home cooking. Added to a finished dish, they enhance the flavor, taste delicious, and are deeply loved by the public. So, what high-yield growing techniques are there for scallions? Let's learn about them together!

1. Planting Time

The suitable temperature for scallions is a warm to cool climate, with the optimal temperature at around 15-25 degrees. In North China, they are generally planted in two seasons, spring and autumn. Spring planting is generally around Qingming, and autumn planting is most suitable at Qiufen. In other regions, whether to sow in spring or autumn depends on the climate. In addition, scallions are highly cold-resistant and can survive the winter, so no special care is needed in winter.

2. Growing Temperature

The temperature for scallions should be determined as much as possible according to their growing habits. Because scallions prefer cool conditions, the suitable temperature is basically around 12 to 22 degrees at best. The temperature should not be too high, because excessively high temperatures will cause scallions to grow slowly. So when some farmer friends report that their scallions are not growing or are growing slowly, temperature is partly to blame. In summer, pay attention to shading.

3. Watering Tips

During the growing period of scallions, appropriate watering is enough. The amount of water should not be too large; overwatering will cause waterlogging, which in turn leads to root rot in scallions. So, based on the scallion's characteristics of being drought-tolerant but not waterlogging-tolerant, just water appropriately. When the soil is dry, water a moderate amount, and large-scale irrigation is not recommended.

4. Soil Selection

Scallions are not demanding when it comes to soil. For growing scallions, simply choose fertile, loose soil with strong drainage and a deep soil layer. For soil that is too alkaline, neutralize the acidity and alkalinity before planting, because highly alkaline soil will affect the growth and development of scallions. Keeping the soil pH at 6-7 is most suitable for scallion growth.

5. Fertilization Management

At the seedling stage, phosphorus fertilizer should be supplemented in a timely manner. During the growing period, mainly supplement nitrogen and potassium fertilizers, and then appropriately supplement trace nutrient elements. At different growth stages, mainly use nitrogen, phosphorus, and potassium fertilizers, and combine them with trace elements when fertilizing, which is more conducive to the growth and yield increase of scallion flower stalks.

6. Harvesting Management

Scallions are a vegetable that can be harvested by cutting, just like chives. Every month or so, scallions can be harvested once. Note here that you should not harvest every 10 days or so just because scallions can be cut for harvest. Too short an interval will cause scallions to run out of nutrients. It is best to harvest once about every month.

7. Tips for Keeping Scallions Fresh and Tender

Scallions are a sun-loving vegetable. The more sunlight and the drier the conditions, the stronger the flavor of the scallions. Conversely, less sunlight and plenty of water will make the scallions taste milder and less spicy. So when the scallions are about to be harvested, you can reduce sunlight and maintain water levels, which will make the scallions more fresh and tender and keep them fresh for longer.
