Question: Maritime pine
Hi I find myself in the southernmost tip of Italy, and more precisely in Portopalo di capo spero - near Pachino ---, in the province of Syracuse, I have several lands dedicated to gardens, in one of which I have several marine pine plants , so called in my part, I have a pine forest where there are about 30 pines of about 35 years each, sunlit at 360 ° and about 50 meters. from the sea, height about 6 meters of the pines and 1m above the sea level.
Seeing that the lower part about 3 meters have dry branches, and feeding them only with water and a lot of sun, I wanted to know to make them reinvigorate a lot what to do or how to conciliate them to enrich the soil of substances that need for these trees and still the pines are cimed like the eucalyptus in order to grow more green again ???
thank you in advance
Answer: Maritime pine
Thank you for contacting us about the questions on your plants through the heading of ...
The Pino belongs to the botanical class of conifers, which includes over 600 species including the Maritime Pine (Pinus Pinaster) diffused mainly in the temperate-cold climatic zone.
This type of plant can be defined as rustic with respect to the soil because thanks to their great radical efficiency it can also develop on rocky and poor soils while it does not tolerate heavy and very humid soils.
Fertilization, for this type of plant, is wrongly considered not essential, therefore there are frequent situations of nutritional deficiencies, especially if the soils are alkaline and tenacious.
Eucalyptus, Eucaliptus globulus, belongs to the Mirtaceae family. It is an evergreen tree, up to 40 meters high in its natural habitat (the Australian regions). It has a globular crown and an erect, cylindrical trunk; arched branches with ramuli of quadrangular section, pendulous; smooth, greenish-gray bark that turns into strips that reveal the bottom of a light blue-pink color. The leaves are greenish-blue, hard and thick. The flowers are isolated or gathered, in the axil of the leaves, in small groups of 2 or 3. The fruits, which have a hemispherical shape, are woody capsules that contain the seeds.
The eucalyptus has flowering, in Italy, between May and July, it is grown in the central / southern regions because it will require full sun. The soils must be moderately fertile, draining and with good water availability.
The pruning of the Pine is never performed, at the limit the dry branches are thinned.
The eucalyptus must be pruned annually or periodically to provide the plant with a correct form of growth, with the topping of the branches it favors the obtaining of lateral shoots for more globose crown forms.
Introduction Maritime pine
The tree of which we speak in this long informative card is known and appreciated by adults and children: it is not the fir tree, but we miss it. In this card we speak indeed of the common pine, also known as pine, domestic pine or maritime pine. It is an indigenous species, that is well present in the Italian territory and perhaps native to our Peninsula. The domestic pine is frequently decorated during the Christmas season, which is why it is much loved by adults and children.
The maritime pine or domestic is an evergreen conifer, therefore a tree, belonging to the family of pinaceae. Its botanical name is pinus pinea L. The tree is native to southern Europe, perhaps just indigenous to Italy. Some specimens also grow in the Iberian peninsula, which includes Spain, Portugal, Gibraltar, Andorra and part of France. Some specimens are also cultivated in Great Britain. Maritime pine grows at altitudes between five hundred and one thousand meters. Difficult to find it in the north and in the cold areas, where some specimens grow only at heights not exceeding five hundred meters. In the Mediterranean and warm areas, on the other hand, the maritime pine creates pinewoods even at a thousand meters high. In these areas, the tree coexists peacefully even with some specimens of oaks.
The maritime pine shows a straight (or slightly curved) stem, twenty-five to thirty meters high. The bark of the tree is gray brown in young specimens and red with easily detachable plaques in mature specimens. The foliage, branched and very extended in the apical part, of dark green color, assumes a wide and umbrella shape in the mature specimens. The basal part of the same, however, remains more and more thin with respect to the apex.
