Before being sold, our trees are checked for the presence of truffle mycorrhiza on the fine roots.
The method applied is based on microscopic analyses. On top, to secure that our trees are really colonized with the right truffle species, a molecular genetic assay was performed to determine the present truffle species.
We can carry out these analyses with the highest standard of knowledge and laboratory equipment. The plants are checked and certified. At the time of sale they will be between one and two years old.
