Plants grown in small containers need regular and well-dosed watering. We avoid leaving the soil dry for excessive periods of time and remember to intensify watering in the event of drought, and to thin it during the cold months. To water the bonsai we can proceed in two ways: - the classic method is the rain method; as it is done for any other plant we will go to wet the surface of the ground by means of a watering can or other sprinkler. We remind you that it is not advisable to excessively move the soil inside a bonsai pot, to avoid damaging the root system; therefore we try to give very fine and delicate watering, possibly using the appropriate bonsai watering cans. - another very good method for watering bonsai is by immersion; it is practiced especially for plants that require large amounts of water, or in the case of very dry soil. Proceed by filling the plant in a basin that contains it comfortably, then insert the water up to the edge of the bonsai pot. Leave the plant immersed in water until the substrate is moistened in the upper part and then lift the jar and let it drain for a few minutes before replacing it in its tray. During watering we also proceed with fertilization; in the case of watering by immersion we avoid dissolving an excessive amount of fertilizer in the water.
