Exposure and irrigation of the Spruce Bonsai

The Spruce Bonsai is made with an evergreen plant that is part of the Conifers, appreciated in the art of bonsai above all because it requires little cultivation care.You can work to obtain any style, except that of Scopa. The sapling is suitable for living outside, in a well-lit and sunny spot. It is a robust and weatherproof plant. The bonsai does not need much water and the frequency of irrigation depends on the climate of the season. However, it is necessary to water when the soil appears completely dry. Water should be poured slowly onto the ground, avoiding wetting the vegetation. After a few minutes it is good to repeat watering to be sure that all the soil has absorbed the maximum amount of water. If frost is expected in winter, it should not be irrigated. In summer it is necessary to water early in the morning or in the evening, avoiding the hottest hours of the day. In winter, on the other hand, it is necessary to administer water precisely in the hours with the highest temperature.

Fertilization and Spruce Bonsai

Fertilization is carried out from the beginning of the spring season to the beginning of autumn, from March to June and from September to October, once or twice a month. This is necessary because the small amount of soil in the pot cannot provide all the nutrients for such a long period. Liquid fertilizer diluted in irrigation water is very practical to use. The operation is carried out after watering the plant with plain water. Solid fertilizer, in powder form, is absorbed more slowly and must be administered every 2 months. Fertilization must be suspended during the hottest months of summer, from July to mid-August. The Spruce Bonsai is usually more appreciated than the white one. It has small leaves,

Pruning operations for the spruce bonsai

The formation pruning must be carried out at the end of the vegetative stasis, therefore at the end of winter, to give the bonsai the desired structure and style. As a general rule, the branches that develop vertically, those that tend inward, those that cross, those that grow from the base of another branch are cut. At the end of the pruning it is necessary to apply the healing mastic on the cuts. Furthermore, the tools (nippers, shears, scissors) must be well sharpened, to make clean cuts without fraying and burrs, and well disinfected, before and after the interventions, to avoid transmitting diseases. Maintenance pruning during the year aims to preserve the shape achieved. Damaged and diseased branches and all branches that protrude beyond the profile of the desired structure must be removed.

Spruce Bonsai: Repotting interventions and application of stakes

Repotting is done every 2 years, for young specimens, and up to 4-5 years for adults. The right time is in early spring or late autumn. The intervention aims to reduce the root system, eliminating the largest and hardest parts, and add soil for the capillary roots. The substrate must be well draining, to avoid water stagnation and therefore root rot. It will consist of a base of sand plus peat and clay. A good combination is made of 65% universal soil and 35% sand. The braces such as tie rods, weights and wires, applied for several months, are used to orient the branches and correct the trunk, to give the bonsai the appearance of a large and mature tree. The wires are copper coated so as not to damage the bark. Weights and tie rods are designed to give the umbrella shape, curving the branches down. In the previous hours it is necessary to wet the branches to make them flexible.
