A method for controlling the planting of olive trees for the continuous mechanical harvesting of the olives using harvesting machines, the method having the following steps: planting parallel rows of olive tree saplings with a spacing between the tree trunks and a spacing between the rows placing trellising on each row placing divergent supports for each tree attaching two divergent branches of each tree, which are arranged in a single vertical plane and in the vertical plane of the row to which said tree belongs, onto a pair of supports removing other branches of said tree adapting the shape of the foliage of the trees so as to impart a configuration flattened in alignment with the rows thereto maintaining said configuration by periodically pruning the trees until the latter reach maturity and bear fruit and removing the supports and the trellising when the trees are fully grown.
