Berry production in South Korea is expected to decrease this year due to low temperature damage and frequent rain, with some crops seeing a significant drop. This is due to various factors including aging of mulberry trees, increased labor costs, and a labor shortage. As a result, the price of these berries, including audi and blueberries, is higher than last year. The decrease in production is expected to continue with bokbunja due to ongoing damage from last year's abnormal weather.
