Protecting the garden from the winds in very exposed areas is often necessary.
Contrary to what you may think, the optimal windbreak barrier made of plant elements is not entirely impermeable to air, nor is it square in shape like a wall.
It must therefore not be constituted of a compact row of trees.
The most effective barrier will be partially permeable to avoid turbulence immediately downstream, and will have a triangular shape to invite the air to climb over it.
In this way we will have an effective barrier for extensions up to 20 times its height.
