The fence hedges are positioned where you want to shield the garden from the outside, without having to necessarily place a metal or wooden structure along the border. Typically, evergreen plants are planted, with compact vegetation throughout the year, so that the hedge always performs its function over time. To have a thick and thick hedge it is first of all appropriate to choose the most suitable plants, and secondly it will be necessary to control the development of the shrubs, to avoid that they tend to empty in the lower part, near the ground. This type of hedges, without any other type of fence, can also be used to delimit some areas of the garden, or to divide it into two distinct properties; in this case they do not perform a defense function from the outside, and therefore it is also possible to use low or not particularly compact plants, as is the case with box trees in Italian gardens.
Place a hedge
The fence hedges they usually settle along the property boundary; before doing so it is good to work the soil thoroughly, to make sure that the plants take root without problems, and immediately begin to develop. The strip of soil must first be enriched with flour manure, which must be spread on the surface, which will then be processed, using a pitchfork, a spade or a motor hoe, if the future hedge is very long. If the present soil is excessively compact or clayey, it is advisable to mix it with sand, peat or universal soil, to improve its texture. Then it compacts slightly and draws a straight line, placing two poles at the ends, between which a thread is spread. Every 75-100 cm the planting holes are prepared, in which the seedlings will be placed, buried at the same depth to which they were in pots. Then the soil is compacted well around the stems and watered.
Choose the plants
There are many plants suitable for forming a fence; if you want a structure that is always compact and shielding, you should choose evergreen plants; in the case instead of a simple delimitation of the border, you will be able to put home plants that lose their leaves in winter, or flowering plants. The hedges are often prepared with all identical plants, so as to form a continuous wall; but it is not obligatory, it is also possible to plant plants with slightly different foliage, so as to obtain a pleasant chromatic effect. We choose disease-free and low-maintenance plants to avoid having to work too hard to keep the hedge alive. Among the most used plants we remind photinia x fraseri, with red leaves, boxwood, viburnum, pittosporum, oleander, prunus, cotoneaster, laurel, euonymus. If you want thorny plants you can choose berberis, or the typical pyracanthe. Small plants guarantee you a lower cost and greater chance of taking root; clear that for a few months the hedge will show large gaps.
Plants in nature develop well spaced between themselves, so that their branches do not intertwine; in a hedge we have forcibly a twisted and very dense development of the plants, which must be controlled and cared for, to avoid that some specimens take over, growing much more than the others and suffocating them. A hedge left in its natural state can become a few meters deep, even occupying the ground outside our border. After the plants take root, we will have to periodically water them, especially during the summer, whenever the soil appears to be very dry. At the end of winter and autumn, we scatter a handful of slow release granular fertilizer, specific for hedge plants, around the stems around the stems. Pruning takes place at different times of the year, depending on the plants chosen; generally in late winter, or after spring flowering. The branches are detached at the top and laterally, to thicken the plants, preventing them from spreading in the area near the ground.
