Holm oak is a valuable species in truffle production, alongside downy oak.
Unlike the latter, the holm oak has evergreen foliage that makes it susceptible to winter frost. It adapts to a wide variety of terrains, including the most arid, thanks to its robustness in the face of drought.
This species is best suited to warm regions and should not be planted above 500 meters altitude.

Ground preparation :

Before planting, it is essential to prepare the ground well. The soil must be loosened and enriched with limestone if necessary to achieve an ideal pH for growing truffles. You can also plant other tree species such as hazel or downy oak , which are also compatible with truffles.

Truffle harvest :

Truffle harvesting usually begins 8 to 10 years after the holm oaks are planted , when the trees have sufficient roots and are in symbiosis with the truffles. Harvesting takes place in winter, usually from December to February , when the truffles have reached maturity. A truffle dog or truffle pig is often used to locate truffles underground.
