Consider the following things before installing a windscreen (wind protection netting) . A distance of 1.5 and 2 m away from the garden/ trees is optimal for maximum wind reduction. A 90 gram per msq will effective privacy, going higher in density will increase the privacy. Young plants will benefit most if winward wind block is applied(also giving a neat canopy). If you have an existing fence, fix the wind block every 1m If you do not have a fence, erect support every 2m and use wires and posts for a wind block.
