Question: Christmas tree
I have an 8-year-old Christmas tree in a pot now (common fir) that I keep on the balcony (I live at 1100 meters)! part of branches that remains let's say closer to the trunk is now very dry and practically "peeled" .. I wanted to know if it is appropriate to move it and put it to "take air" in another place for a while, I don't know to oxygenate on both sides. Despite its age it continues to germinate in spring, but only in the ends and not near the trunk where the branches remain thin and dry. What could I do? I am fond of it (!) And I would be sorry if he died!
I thank and cordially greet you
Answer: Christmas tree
Christmas trees are usually firs, which in Italy live only in the mountains, in the Alps and also in some areas of the Apennines; rightly keep your fir tree on the terrace, since you live in a cool area, harsh winter and not too hot summers are certainly more suitable than a constantly hot climate in the house; and indeed, in this way, your fir has survived very well for about 8 years. But on the terrace there is something missing that a fir tree could find in a wood, that is a lot of space and the correct insolation, which in nature can reach all sides of a tree. And in the woods, as happens on your terrace, in the shaded areas it is difficult for new shoots to grow and the branches often dry up completely. In some very dense and dense woods, fir trees completely lose their branches in the lower part, which continue to develop only at the apex of the stem, like a sort of hat. This is because the leaves of the plants basically perform the function of transforming sunlight into energy for the plant, through chlorophyll photosynthesis, as we all know. Some plants have adapted over time to live even in poorly lit areas, and therefore even if they receive only small quantities of direct sunlight, they keep their foliage green and shiny; this is not the case for firs, which in nature are used to receiving direct sunlight for many hours a day. So in the area where your plant never receives sunlight, being close to the walls of the house and therefore in complete shade; for this reason, the needles and branches in that area cannot fully perform their functions, and therefore the plant, over the years, once the needles have fallen, does not renew them with further shoots. To overcome this problem, usually when you keep a tree on the terrace, you try to expose it as much as possible to direct sunlight, placing it in a bright place on the terrace; however, during the hottest summer weeks, it is placed in the shade, so that it does not suffer from the summer heat. If you are forced by the space you have available to keep your fir constantly in that position you can think of turning it periodically, once a week (more or less), so that every part of the plant can be exposed to sunlight.
