Constant air currents in open areas blow moisture out of the soil, break the shoots of young trees and lower the temperature in the root growth zone. A blind corrugated board fence creates a rigid aerodynamic barrier, causing the effect of turbulence: the wind rolls over the obstacle and hits the site with double force.
The biological barrier of dense plantings works as a filter. The crowns of trees and shrubs cut through the wind flow, reducing its speed by 60-80 percent. Air passes through foliage and needles, losing kinetic energy without creating destructive swirls.
Aerodynamics of a hedge
The effectiveness of a windbreak depends on its permeability. The optimal crown density is 50-60 percent. If the plantings are too dense, they work like a monolithic wall, forming a low-pressure zone behind them, where cold air rushes in. The delicate structure of the branches smoothly slows down the flows.
The height of the green shield determines the area of the protected area. A 5-meter-high tree creates a comfortable microclimate at a distance of up to 30 meters deep into the site. The root system of plants forming the barrier should be rod-shaped or deeply lobed so that the trees are not turned out of the ground during storm gusts.
To form a reliable barrier, a tiered planting scheme is used:
- the first row from the prevailing winds is formed from tall coniferous or deciduous trees.;
- the second row is filled with dense shrubs to cover the trunk of the first tier.;
- the third row consists of low-growing plants compacting the lower blown level.
The staggered arrangement of the seedlings eliminates the appearance of wind tunnels. Plants are planted with overlapping crowns, forming a solid green mass already in the third year of vegetation.
Choosing sustainable breeds
Coniferous trees provide year-round protection without dropping the shielding layer for the winter. The common spruce easily tolerates shearing and builds up dense biomass. The Western thuja of the Brabant variety gives an annual increase of up to 40 cm, forming an impenetrable shield when properly molded. However, the root system of spruce is superficial, which requires protection from the wind on sandy loam soils.
Hardwoods have a more powerful branch framework. Hornbeam is distinguished by its tough wood and the ability to keep dry foliage on branches until spring. Hawthorn and blackthorn create impenetrable thorny thickets, additionally protecting the site from stray animals. The branches of these shrubs are intertwined so tightly that they block even strong gusts.
Fast-growing willows and poplars are used to quickly create a shield. They stretch by one and a half meters per season, but their wood is fragile. Powerful gusty winds often break thick poplar branches, so they are used only as a temporary barrier while slow-growing but strong oaks and linden trees grow up.
Planting and rooting technology
The creation of a windbreak begins with the preparation of a trench. Digging separate pits for each seedling disrupts the root growth line. A deep trench 60 cm wide is filled with a nutrient substrate, which stimulates the root mass to develop along the planting line, linking the plants into a single underground monolith.
Seedlings of coniferous species with a height of more than a meter require mandatory fixation. While the root system has not grasped the ground, the windage of the crown loosens the trunk, breaking off the thin suction roots.
The algorithm for fixing young trees:
- installation of three support stakes around the trunk in the shape of a triangle;
- stretching synthetic twine using rubber clamps to prevent damage to the bark;
- mulching of the trunk circle with coarse bark to preserve moisture and weigh down the surface layer of the earth.
Regular pruning in the early years of life stimulates the awakening of dormant buds on the trunk. Shortening the apical shoots by a third redirects growth hormones to the lateral branches, forcing the crown to branch and gain the necessary aerodynamic density.
