Oak bonsai tree: a spectacular plant in its form
The oak bonsai tree appears as a spectacular plant for its huge and ancient tree aspect. It is characterized by very small leaves of an intense green, very thick trunks and a rough bark which tends to come off from the plates and from which the cork is obtained. This type of oak is an evergreen and has a disordered expanded habit and that's why its shapes have a strong visual impact. In the period between May and June it develops both male, yellow-green flowers on the branches of the previous year, and female flowers characterized by a green color on the branches of the current year. While the fruits born later and consist of brown-colored acorns.
The care of oak bonsai tree is quite complicated, but if carried out with due attention it can give very satisfactory results to those who cultivate it. During the spring months it should be exposed to sunlight, while during summer months, especially July and August, it must be repaired so as not to risk being damaged. In winter instead it resists to very low temperatures.
Watering depends much on the climate in which the bonsai is cultivated, that's why it is necessary to pay attention to soil dampness: when it is not wet enough, the plant needs water. In winter months, watering has to be done more rarely because the oak tree is in a vegetative state.
Every two or three years the oak bonsai tree needs a repotting during spring when the first buds are born. The soil in which it is planted must consist of universal soil and coarse sand. Moreover, in spring, but also in autumn, fertilization must be carried out every four weeks.
The pruning of the oak bonsai tree negatively affects the growth of the plant and therefore it is recommended to carry it out exclusively in winter and at the roots when repotting.
