A recent heatwave has caused a significant increase in the prices of leafy vegetables such as lettuce, spinach, and sesame leaves in South Korea. The wholesale price of spinach has risen by approximately 92% from last year, and the price of green lettuce has increased by 62%. This is due to reduced production as these vegetables are sensitive to heat. The decrease in agricultural manpower due to COVID-19 and the impact of heat waves on foreign workers in mountainous areas have also contributed to the price hike. Homeplus predicts that these high prices are likely to persist as the heatwave is expected to continue into next month.
