Sweet chestnuts are native to Hungary but are only grown on a small scale due to their specific ecological requirements. The annual yield is between 200 and 500 tons, with most of the plantations extinct and no major plantations in the country. Imports range from 2000 to 2500 tons per year, primarily from Italy. The cultivation of sweet chestnuts is risky due to fungal disease and a new pest, the sweet chestnut wasp. Studies on the introduction of a natural enemy of the sweet chestnut beetle show promising results for pest control.
