Shell function
Hedges are often used as the boundaries of gardens, and barbed wire can be added to barbed fences, high fences or hedges. Hedges can guide tourists to choose a tour route and visit according to the marked scope. Those who don't want tourists to pass can be fenced off with hedges.
Zoning and barrier landscape
Hedges or green walls are often used in gardens to divide areas, shield the line of sight and separate spaces with different functions. It is best to use evergreen trees to form a green wall above the line of sight. For example, children's playgrounds, open-air theaters, sports fields and quiet rest areas are separated to reduce mutual interference. In the natural layout, there are local regular spaces, which can also be isolated by green walls, so that the layout forms with strong contrast and different styles can be alleviated.
The pattern of flower beds and ornamental lawns with the middle fence as the dividing line and the short fence as the edge of the flower border. Adopt special planting methods to form a special scenic spot. In modern times, there is also "hedge landscaping", which combines the landscape theme, uses flexible planting methods and plastic pruning skills to form a landscape that fluctuates like a strange stone.
Landscape background
Evergreen trees are often trimmed into various forms of green walls in gardens as the background of fountains and statues, and their height should generally be commensurate with the height of fountains and statues. Dark green trees with no reflective color should be selected, and the hedges as the background of flower border are generally evergreen high hedges and medium hedges.
In all kinds of green space, in order to avoid the boring elevation of retaining wall between two highlands with different heights, hedges are often planted in front of retaining wall to beautify the elevation of retaining wall.
