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.

Selection of hedge height

Hedgehogs with different heights have different uses and suitable tree species selection. When designing, the appropriate hedge height is often selected according to different functional requirements.

High hedges or green walls—

It is often used to separate spaces and block gables, toilets and other places that should not be exposed. Mainly used for noise prevention, dust prevention and space separation, most of them are shrubs or semi-trees planted at equal intervals, which can be planted in single row or double row.

Features: The green wall is generally above 1.6m, and the high hedge is generally above1.5m. The plants are tall, the population structure is compact and the texture is strong.

height

The green wall, 1.6 meters high, can completely block people's sight;

function

Sound barrier, dust barrier, decorative barrier;

Ecological habit

According to ecological habits, it can be divided into evergreen hedges, semi-evergreen hedges and deciduous hedges;

Pruning and shaping: according to pruning and shaping, it can be divided into non-pruning and pruning hedges, that is, natural and integral forms. The former usually only needs a small amount of pruning to adjust the growth potential, while the latter needs regular pruning to maintain the shape and appearance. In the same scenic spot, natural hedges and whole hedges can form completely different landscapes, so we must make good use of them.

Hedges can be trimmed into different forms according to people's different requirements. Conventional hedges must be trimmed several times a year. In order to make the bottom of the hedge full of bright and lush branches and leaves, its cross section is often cut into square, rectangular, trapezoidal, dome-shaped, battlements and slopes. The number of pruning varies with the growth and position of tree species.

① Trapezoidal hedges, narrow at the top and wide at the bottom, are conducive to the growth and development of lateral branches at the base of the ground, and will not die and be sparse due to lack of light.

(2) The rectangular hedge is stiff in shape, the top is prone to snow and compression deformation, and the lower branches are not easy to receive sufficient light, resulting in some dead and sparse.

(3) Dome Hedge This hedge is suitable for use in areas with heavy snowfall, which is convenient for snow to slide down the ground and prevent deformation.

4 natural hedges Some shrubs or small trees often grow into this shape if they are planted with high density and are not pruned regularly. The crown line is generally horizontal, the width of the outer edge line is unchanged, and the spacing between trees is even, which is arranged in a straight line or geometric curve.

Planting pattern

According to planting methods, it can be divided into single row and double row. Generally speaking, in China gardens, double rows are used to achieve quick results. Some gardeners advocate single row on the grounds that single row is beneficial to the balanced growth of plants, while double row is not only not conducive to balanced growth, but also expensive and easy to breed weeds.
