Question: care of the olive tree
my very beautiful olive tree has a hollow trunk. When it rains it fills with water. This is not good for him, but I don't know how to fix it. I would like advice. thanks
Answer: care of the olive tree
it often happens, in the olive groves but not only, that the trees combine portions of troco cave, even the large ones; if the wood inside the cavity is healthy, in theory you shouldn't worry, especially if the water that remains there tends to evaporate quickly; but if the cavity is so large, and shaped in such a way as to serve as a collection of rainwater, then surely with the passing of the days the water contained in it will be able to macerate the wood and favor the development of fungi, bacteria, insects , which can then quickly infiltrate the trunk, due to the wood macerated by the water. Therefore, if the water remains in the cavity for short periods of time, you can simply keep the portion of wood periodically treated with copper-based products, in order to prevent the proliferation of fungal diseases. If, on the other hand, the water stays for many days, you can think of creating cracks, in order to drain the water; in this case you will have to work the wood around the cavity, in the lower part, so as to create slits, from which the water will come out more quickly; clear that the work should be done in a dry climate, with instruments that are well cleaned and disinfected, and the rest of each cut should be treated with a fungicide and covered with mastic. Perhaps it would be appropriate to show the tree to an agronomist, so that he can advise you for the best; olive trees are usually grown in areas with a warm climate and in a sunny position, and therefore in areas of this type any water deposits should not remain on site for weeks, but only for a few days. You happen to see trees with three cables, which have been filled in some way, you can try this option, but first you have to dry the wood very well, and treat it with fungicides and insecticides, to prevent the filler that you will put on it to act as hatching chamber for pests of any kind; once it even happened to see logs filled with cement, luckily a completely disused practice. You can also think about waterproofing the cavity, even if here too you will first need to be sure that there are no insects or fungal parasites, and then cover everything with pruning mastic or tar, so that the water does not act as an environment favorable for pest development.
