1. The best time to transplant green onions is mid-June, but the planting should be completed in late June.

2. Method: When transplanting green onions, the land must be prepared first. After the plot is prepared, trenches should be dug in the north-south direction. The distance between the trenches should be about 80 cm, and the depth and width should be 30-35 cm. When starting seedlings, dig deeper and try not to damage the root system. After plowing, some disabled and diseased seedlings are eliminated, and the seedlings are divided into three levels according to their size, thickness, and height. Try not to use third-level seedlings when the seedlings are full. After treatment, plant it directly into the soil, then water it once with water and spray it with a new high-fat film.
