Like all bonsai, it must be wet at any time of the year, although naturally the hottest days require more frequent watering: the plant, however, needs water whenever the substrate is dry. Given, therefore, that defining the scope and periodicity of the intervention is quite complicated, as variables dependent on the climatic zone, the season, the size of the pot, the draining power and the quantity of soil, the need to water is still valid as a universal rule. gradually and very slowly, so as to allow the soil to remain moist for as long as possible, retaining a greater amount of water. In summer it is better to water the pomegranate bonsai early in the morning or in the evening hours; in winter, on the other hand, water must be supplied during the hottest hours, postponing for administration if frost is expected. As regards fertilization, which is useful for constantly integrating the nutrients that are consumed quickly, it must be performed every twenty days from March to September, during the growing season, but not during flowering. Furthermore, interventions must be suspended in July and in the first days of August, in correspondence with the hottest days of summer.Naturally, the plant must be protected from potential attacks by parasites: an effective preventive action is carried out by fungicides and insecticides, useful in particular to avoid damage caused by fungi, aphids and red spider. The treatments against parasites, however, must be concentrated during the winter season, in correspondence with the vegetative rest, when the bonsai has no leaves, while they must be avoided during the flowering period.

During growth, the formation of the plant can be helped by the use of tie rods and threads, to be applied on young branches (more sensitive and therefore more elastic: they can be corrected more easily, but care must be taken as they are also more delicate) . Using copper wires of two or three millimeters in diameter, the branches can be lowered, anchoring them to the vase. Furthermore, the action of the tutors, preferably usable in the vegetative period, should not be underestimated. The root system produced by the pomegranate bonsai it is quite large: for this reason, there is a need for rather frequent repottings, every three years at the most, both for the young specimens and for the old specimens. The operation must be carried out in the spring, when the buds begin to activate. To avoid stagnation of water, the substratum, strictly not acidic, must be sufficiently draining: the recommended composition provides fifteen percent of universal soil, possibly filtered, fifteen percent of coarse sand and seventy percent of akadama; alternatively, fifteen percent leaf soil and eighty-five percent akadama may work. When repotting, it must be ensured that the root system does not present asphyxia, and that upstream of the primary root there are rootlets that allow the root and the branch connected to it to survive. It is good to know that the pomegranate bonsai does not digest transplants, as it has a tendency to originate the capillaries at the apex of the root system: this is why cutting the roots requires moderation and attention.

Speaking of styles, the pomegranate bonsai welcomes the sloping trunk, cascading trunk, multi-trunk, random upright, or raft trunk. The fertilizer to be administered must have a reduced nitrogen content, and high quantities of potassium and phosphorus: the ideal solution represented by tablets based on fishmeal, rapeseed and bone meal.
