A Detailed Guide to the Latest Planting Methods and Timing for Scallions

I. Planting Time

Scallions are relatively cold-tolerant. They are generally sown in March-April and harvested in June-July, or sown in September-October and harvested in April-May of the following year. In southern regions, they can be planted in both autumn and winter.

II. Planting Methods

1. Soil: They like loose, nutrient-rich soil with strong drainage and aeration, and are not suitable for planting in sandy soil.

2. Light: They prefer gentle, diffused light. If the light is too strong, they need to be shaded; otherwise, the leaves may turn yellow, the fiber content may increase, and the taste may become poorer.

3. Temperature: They prefer a relatively cool climate and are highly cold-tolerant. During germination, 13°C-20°C is most suitable; during stem and leaf growth, 10°C-23°C is optimal. When the temperature exceeds 28°C, their growth rate drops noticeably.

4. Watering: Their root system is relatively sparse, so they need less water than large scallions (Welsh onions), but they are not drought-tolerant, so the soil should be kept moist.

5. Fertilizing: Spring and summer are their growing seasons, so 1-2 additional feedings can be applied as needed. The first feeding can be done at 20-25 days, and the second feeding can be done at 12-15 days.
