Boxwood is an evergreen shrub native to Europe and Asia. It belongs to the genus Buxus which includes several species, some of which can reach four meters in height. The plant has an erect and bushy character and is characterized by a very thick and thick crown. The leaves are petiolate, long and ovoid, dark green and measuring up to two and a half centimeters. The flowering is almost imperceptible since the flowers are very small and are lost between the dense foliage of the plant, while the fruits are capsules containing brown seeds. This plant is a rustic variety that is well suited to our climate and our soils and can grow both in the sun and in the shade. Its ease of cultivation and its few requirements, together with the dense and compact crown, make it one of the most widely used plants in the creation of hedges.
Exhibition and planting
As mentioned previously this plant is a very rustic variety and it adapts easily to any exposure, even if it prefers the partial shade in hot climate regions and sun exposure in cold regions. Once planted it tends to form immediately a dense network of roots that allow the plant to recover quickly from the racking without being affected by the passage from one environment to another. Before implanting such specimens, however, it is necessary to create the right environment. The first thing to do is to dig a hole that is at least twice as large as the amount of land the plant was used to. Furthermore, before planting it, it is necessary to fertilize the soil adequately, taking care to add some gravel if the soil is particularly clayey. This expedient will make it more draining and will favor the correct development of the plant avoiding lethal root rot, given that these plants do not tolerate water stagnation.
Among all the existing varieties the most suitable ones to constitute boxwood hedges they are mostly dwarf varieties because, growing less in height, they are more manageable. However also the Buxus Rotundifolia, which is not dwarf, with its sapling bearing is much appreciated and used for this purpose. Once we have identified the variety that interests us, all we have to do is design our hedge. Respecting the aforementioned rules to ensure the right soil and the right exposure, all that remains is to plant the plants about half a meter from each other and half a meter from the border we want to delimit. We will notice a slow and compact growth. Once the hedge is formed you will have to intervene with pruning, an operation that will be carried out periodically, twice a year. The first time in June to give the right shape and compactness to the hedge by adjusting its height and width, the second instead in September to prepare the plants to overcome the winter period.
Watering and fertilizing
This plant loves a fairly dry soil, so it usually needs irrigation only in the summer, always making sure that the soil between the irrigation is dry. During the rest of the year the seasonal rains tend to be sufficient to provide the right water supply to the plants. In the case of young specimens, however, it must be said that it is advisable to supply water in the event of prolonged drought. As far as fertilization is concerned, to guarantee the healthy development of the box, granular slow-release fertilizer is administered in the spring, before the vegetative growth, while in autumn it is advisable to use mature manure. With these small tricks we will achieve and preserve boxwood hedges healthy and lasting.
