Domestic pine, Pinastro, Maritime pine - Pinus pinaster


GeneralitŠ°


With the term Pinus pinaster we refer to the family of evergreen pine trees originating from the Mediterranean and from the Atlantic areas of Portugal and France, they grow quite rapidly and reach sizes between 30-40 m, a feature that makes them suitable for reforestation in coastal areas . The genus can be divided into two large groups, the Mediterranean and the Atlantic one, which have only small differences between them. The maritime pine it has greyish-brown bark, with deep fissures and thick plaques that detach, leaving brown or reddish spots, the wood is rich in resin which in fact is often extracted from this type of tree. The stem of the pinastro has a fairly sinuous course and the branches are arranged like a crown, in the upper part of the stem, growing like a candelabrum; the crown is conical, usually it becomes very irregular with the age of the plant. The needles of the domestic pine are light green, gathered in groups of two, very long, up to 18-20 cm, and rigid. The Pinus pinaster has conical pine cones, which remain long on the branches, and male and female flowers on the same plant.

Exposure



The specimens of pinus pinaster or maritime pine they need sunny positions, they are usually cultivated in flat or hilly areas, never above 800 m. Pinastro trees prefer places with fairly abundant rainfall and possibly a good quantity of environmental humidity; they are not afraid of salt and strong sea winds, while they can be damaged by too persistent frosts. It is advisable to take greater care of young domestic pine specimens, so that they can acquire the necessary strength.

Ground



The pinus pinaster it has no particular soil requirements, although it prefers siliceous sandy soils, possibly slightly acidic. In general it is easier to adapt in very poor soils than in soils rich in humus. The soil must guarantee good drainage, as water stagnation causes problems to the plant and can compromise its growth.

Multiplication



The multiplication of this variety of tree occurs by seed, to be used at any time of the year, just picked from the pine cones. The seeds must be germinated in a container filled with peat and sand in equal parts, the seedbed must be kept in a warm and humid place, away from drafts. Plants have very delicate roots when young, so they must be handled with great care, it is advisable to grow them in a container for a few years before planting them.

Domestic pine, Pinastro, Maritime pine - Pinus pinaster: Pests and diseases



This kind of trees fears the attack of aphids and mites; often the processionary of the domestic pine causes serious damage, although usually of negligible nature for the plant.
Another type of parasite that can cause damage to the pinastro is the cochineal corticola of the maritime pine. To identify its presence it is sufficient to observe the foliage of the pinastro and see if there are redness and patches that can lead to complete drying up. This type of insect is very aggressive and it is good to intervene preventively with targeted treatments, which preserve the plant; in case of massive diffusion, it may be necessary to resort to a drastic cut of the affected parts.
