Oregon is among the world’s best regions for farming European truffles. With development of modern seedling inoculation methods, 80-90% of French truffles are now grown in orchards of inoculated oak and hazelnut trees. While this is a new industry in North America, there are dozens of North American orchards in production, including six in Western Oregon. Learn about climates, soils, orchard establishment, production costs, markets, and results to-date for various cultivated truffles. If you have bare land with well drained soils and available irrigation water, truffles may work for you.
