When can we plant truffle plants?

“At St. Catherine, everything takes root,” as we say in France; St. Catherine is on November 25th. An autumn planting is always wished to a spring planting: The trees are dormant and transplanting is best. The plants already installed during Winter start faster in spring and suffer less from lack of water in summer. Exception made for the green oak: in big frost situation, we prefer to wait out the Winter. Generally, avoid planting in periods of strong frost.
