Pino, Pine with five needles - Pinu pentaphylla


GeneralitŠ°


evergreen conifer native to Asia, and in particular to Japan; in nature these trees can reach 25-30 meters in height. It has an erect trunk, with smooth bark in young specimens, which becomes thick and wrinkled with age; the foliage is pyramidal, very dense and branched, it tends to slightly round in mature specimens; the needles are bluish-green and group in mazetti of five, as the name suggests. It produces small sized inflorescences and then small dark brown pine cones. This conifer is quite advisable for beginners, since it is easy to cultivate, although it may be difficult to shape the branches and contain the growth of the needles, although there are many cultivars, some of which have small needles.

Pruning and exposure




Pruning: trim the buds when they are still closed, at the beginning of spring; training prunings are practiced in autumn or late winter. The wire can be positioned in the cold months of the year.
Exposure: place in a sunny and well-ventilated place; in the hottest months of the year it is good to transfer to a shady place, to avoid excessive sun exposure and high temperatures; generally these conifers do not fear the cold winters, even if in cases of very intense and prolonged frosts it is good to cover the vase with tnt.

Watering


Watering: from March to October water regularly, waiting for the soil to dry on the surface between one watering and another; in the cold months it is preferable to thin out the waterings, supplying water only when the ground is well dry. In the months of greater vegetative growth it is good to provide universal fertilizer every 10-15 days. In summer it is good to vaporize the foliage often with demineralized water.

Ground


the pinus pentaphylla they love well-drained, loose and soft soils, possibly with a slightly acid ph; It is good to use a compound consisting of a part of peat, a part of clay and a part of sand. These plants grow fairly quickly in the early years, they should therefore be repotted, at the beginning of spring, every 2-3 years, avoiding to shorten the roots too much.
