Why is new ginger cheaper than old ginger?

The reason why new ginger is cheaper than old ginger is because of its large supply and short storage time.

New ginger is usually harvested in summer. At this time, the supply was large, and a large number of fresh ginger roots in farmland were picked and listed, which led to an adequate supply of new ginger in the market. In contrast, old ginger is stored for a period of time before being sold, and it can be supplied in other seasons such as winter. However, due to the long storage time and the high cost of keeping ginger fresh, the price is relatively high. Because of the large supply and short storage time, the price of new ginger is relatively low, which is cheaper than that of old ginger. This is the result of market supply and demand and storage cost.
