Planting density of truffle trees

The Black Périgord Truffle - Tuber melanosporum

The planting density for tuber melanosporum varies between 250 and 400 plants per hectare.
It is important to have enough trees to ensure that the ground is well impregnated with spores. Do not plant the trees too close together as the Périgord truffle needs the sun’s rays to reach the ground if it is to develop.

Planting density of truffle trees

- High density (ex : 5 m x 5 m, equals 400 plants / hectare) : should yield quickly but the life expectancy of the truffle tree will be shorter as it will be stifled. Avoid this on fertile soils or with quick developing trees such as the hazel or common oak.

- Low density (ex : 6 m x 6 m, equals 277 plants / hectare) : contrarily, they will be longer to yield but their life expectancy will be greater. The better the soil the further apart the trees are planted and the more intense is the cultivation.

 
Planting density of truffle trees

Bourgogne Truffle - Tuber uncinatum

The planting density for the Tuber uncinatum varies between 800 and 1200 plants per hectare.
The Bourgogne truffle develops best in a shady situation. The trees are therefore planted closer together than for the Tuber melanosporum.

- High density d(ex : 2,9 m x 2,9 m, equals 1200 plants / hectare).

- Low density (ex : 3,5 m x 3,5 m, equals 800 plants / hectare).
