It happens that live fences of long standing rarefy at their bottom, so they should be cut more frequently both on the top and on the sides. Live fences do not need to be of strict geometric shapes, but can weave and form irregular shape, showing thus casualness and creativity. Also, the plant material for the live fence can vary and may be blended in different ways, resulting in a richness of textures and shapes.
Live fences and various green sculptures are back in trend today. Choice of plants for the hedges is really great, and the application itself is very diverse.
Life fences are divided according to purpose, method of planting, the form, and amount and by type.
According to the purpose, live fences can be protective and decorative.
Protective live fences protect against unwanted looks, sun, wind, dust, exhaust fumes, noise and keep out the wildlife, livestock and various pests. These live fences should also fulfil an aesthetic function.
Decorative live fences may be green (conifers, tall and evergreen leaves) and flower (deciduous shrubs, flower vines). Furthermore, the decorative live fences also have a protective role.
When it comes to the way of planting, live fences may be single-row, double-row and multi-row fences. Single-row live fences are usually formed of conifers, evergreen leaves and flower bushes. Plants are planted at distance of half to one meter. Young plants ligustrum, berberis, evonimus, hibiscus... are used for double-row live fences. Plants are usually planted in the channels, following the zig-zag principle, and at a distance of 30 cm. Nine plants is needed for a meter. These fences, with regular maintenance, quickly fulfil their function. Multi-row live fences are made of one or more species, usually for the purpose of wind and snow protection.
According to the shape, live fences are classified to free growing and shaped. Free growing hedges are raised of naturally shaped conifers (columnar and emerald thuja, juniper - celestial rocket, columnar yew, cypress), low leaves, or flowery shrubs (meadowsweet, weigela, hibiscus). Shaped live fences are formed of species that tolerate pruning and quickly regenerate. They are known among people as hedges. Their shape (cross-section) may be different (trapezoidal, triangular, oval ...), but they must be narrowed from the base to the top.
In terms of height, live fences may be high fences, or green walls (over two meters), half-high (half a meter to two meters) and low hedges or borders (less than half a meter). Live fences may be formed from one, two, or several species. Monotype fences are the most common, and two species may be combined in width.
