Juniperus communis is a species represented by majestic shrubs or small and medium-sized trees that develop mainly in height.
In any case, juniper, a common name for this genus, is a rustic plant, which reaches a height that varies between 2 and 4 meters and a diameter that can even be around 4 meters.
The flowers of this type of plants are very small, almost imperceptible; the foliage consists of small leaves similar to needles, scented and dark green. The fruits are small round / oval-shaped berries of green color during the first years, blue starting from the third.


As for the best exposure, being a typical plant of the woods and moors of the northern hemisphere (it often grows luxuriant even in the coniferous forests), the juniper resists even at cold temperatures, even to those that arrive far below of 0 ° C, up to -13 ° C.
The best position for its development however must be rather sunny or partial shade. It is a hardy and resistant plant that is not particularly affected by the action of the wind, so it can be cultivated without problems even in rather windy areas.


The best soil for cultivation must be well drained.
The soil to be used is porous or in any case able to retain water in order to have the correct degree of humidity, without the formation of water stagnation. The best soils are neutral or slightly alkaline and does not grow well in clayey soils. Juniper is however a plant that can adapt even in areas that are not particularly welcoming, managing to grow spontaneously even in rather dry places.


The multiplication of Juniperus communis to obtain new specimens must take place during the autumn season and is obtained by taking woody cuttings from the mature plant. The new cuttings should be planted in a substratum composed of peat and sand and should be rooted in a cold greenhouse during the first winter, before being placed outdoors. The cuttings are arranged individually in the pots.
These plants can also propagate by seed.

Cultivation techniques

Juniperus communis is a robust and resistant plant to which the attention to devote is few. The use of leaves and berries to produce digestive liqueurs should be emphasized.
Precisely for this reason the Juniper is used both in the culinary and medicinal fields. Finally, the leaves are quite irritating.
Juniper plants need to have constant watering during the first years of growth, taking care to check that water does not build up, while adult specimens, once grown, can easily withstand periods of drought.

Juniper - Juniperus communis: Pests and diseases

Being this rustic and resistant variety, it appears to be little affected by the parasites but may show signs of the presence of scale insects, for which it is advisable to intervene with the use of specific insecticidal products. Another problem that characterizes this kind of plants is that of root rot, usually caused by the formation of water stagnations due to too compact soil.
