Compared with the traditional planting method, this kind of planting method has higher economic benefits, and farmers will have more money if they go on the market out of season.

Therefore, it is critical to maintain a certain number of watering times and maintain the wettability of the soil, especially in the seedling emergence period.

In addition to the sufficient base fertilizer given before, it is also necessary to apply fertilizer properly in order to ensure its growth. In order to keep dandelion wild, we usually choose farm manure or organic fertilizer instead of chemical fertilizer. Generally speaking, after topdressing, it should be watered in time to fully absorb nutrients.
