Slowing the Wind in your Garden

One of the best ways of protecting your bonsai is to slow the wind in the local area of your trees.

Rather than trying to stop the wind thereby creating turbulence and increased wind speed, it far better to diffuse and diminish the force of the wind by partially blocking it.

By using a partial barrier such as a large plant, trellis, bamboo screen or hedge, the wind is allowed to pass through but with much less speed and force.

By allowing the wind to pass through the partial barrier but with reduced force, the wind speed and strength is radically dissipated It is estimated that a thick hedge or dense tree (such as a conifer) will gently reduce wind speed for a distance of 15-30 times its height.

In the above diagram, it is possible to see how attaching a partial barrier (a screen or trellis) to the top of a solid barrier (such as a wall or fence) can remove the problem of turbulence on the lee (sheltered) side by removing the 'drag' caused by the solid object.

In a typical English garden surrounded on 3 sides by walls or fencing, wind speeds of only 15-20 miles per hour will regularly blow over bonsai and garden plants. By planting mature trees and with the use of strategically placed bamboo screening around the perimeter of the garden, gusts of 50mph to 60mph can have little effect on your bonsai.
