Potato Prices and Market Trends in Autumn 2026

Potatoes are one of the clearest examples of seasonality on the Lithuanian market: prices can swing several times within a year. Autumn, when the main harvest begins, is usually the time when market prices start to fall. It is worth understanding why this happens and what it means for growers and buyers.

How the price changes over the year

Early in the year, market prices for potatoes typically hover around 70 cents per kilogram, but in June, when the first fresh, thin-skinned new potatoes appear, prices can jump to EUR 2-2.5/kg. This reflects the highest growing costs for the earliest harvest (frost protection, irrigation, lower yields). In August-September, as the main harvest begins, prices gradually decline, returning to 60-70 cents/kg by October-December. In winter, once potatoes become a daily rather than seasonal item, prices stabilize until the new harvest. This is the usual pattern, but in 2026 it was distorted by the smaller crop in Western Europe and Poland, which we cover in other articles.

Why prices differ between regions

According to Dr. Evaldas Stankevičius, chief economist at the Agricultural Data Centre's Market Information and Economic Analysis Division, price differences are driven not only by harvest volume or seasonality, but also by the local market. In major cities, especially Vilnius, potatoes are more often sold pre-sorted, washed or packaged, which naturally raises the price. In Klaipėda and Marijampolė counties, more trade happens directly from growers, so the chain from field to counter is shorter and the price is lower.

2026 season specifics

June 2026 data shows that new-crop potato prices moved differently depending on the sales channel. The average price in major retail chains fell from EUR 1.48 to EUR 1.29/kg compared with the same period last year. The average grower price stayed almost unchanged at around EUR 0.78/kg, while at markets the asking price in early June was about EUR 2.23/kg. These are early-crop prices. In autumn the situation changed: the crop shrank in Western Europe and Poland, and open-market prices rose.

What this means for growers

Price depends on the sales channel, the harvest and quality. When supply shrinks in neighboring markets and open-market prices rise, the most important things for a grower are to know their production cost, ensure quality and have several buyers. A stable, disease-free crop sells better than one of uneven quality, and certified seed material is the first step toward such a crop.
