Continuous rainfall is a great threat to potatoes that have not yet been unearthed. Continuous rainfall combined with the scorching sun after the rain can easily make potatoes rot, and unearthed potatoes will rot if they are not well ventilated or stored improperly. In this way, the price will not rise in the short term, and it should rise slightly after a while.
Personally, more mature markets also need to pay more attention to market dynamics.
