Imported blueberry prices in Poland have been decreasing since late January, with a significant drop in early February, making them 17% cheaper than in early March last year. This is attributed to a large harvest in Spain, which has increased supply to the Polish market. However, the declining trend in Spain's blueberry prices has halted this week, and prices may rise due to unfavorable weather conditions. This could potentially cause a price increase in the Polish market in the near future.
