You can grow truffles in a wide range of climatic zones worldwide. In northern temperate zones down to northern Africa, its possible to cultivate summer/burgundy truffles (Tuber aestivum syn uncinatum) whereas the winter truffle (Tuber melanosporum) can be grown in Mediterranean climates. In fact, there are truffle species for nearly all climates and soil types, even some white truffle species can be cultivated. Here at Mycorrhizal Systems, truffle cultivation is our thing and we run research sites in nearly 30 countries worldwide, working with a very wide number of host plants and truffle species. Around 95% of all the truffles in France are now cultivated.
