Planning your orchard
Before you order your truffle innoculated seedlings (please read our advice on verification of seedling quality), you will need to decide how to set out your truffière.
Typically, trees are planted in rows running north south to maximise the sun on the ground.
Planting densities vary depending on the truffle species, intended orchard management, and climate. Typically planting densities of around 400 trees per hectare are recommended for Perigord black truffles. However this may vary depending on the local climate, the type of tree planted (oaks are big trees and may do better with a reduced planting density), and the intending pruning regime (hard pruning trees to keep them below 3m may allow a higher density of trees). For Burgundy truffles, higher planting densities will encourage early canopy formation to create the shady conditions the truffle prefers.
If you are going to install irrigation, it’s easiest to do so before the trees are planted. A good idea is to ensure the irrigation design is such that the irrigation lines can be removed or lifted to allow soil cultivation around the trees each spring. Cultivation around the trees isn’t necessary until the trees are around five years old.
