The cost of bonsai
The cost of a bonsai can range from a few euros to several hundred euros: many factors affect the price, such as the origin of the plant (and the related transport costs), the species, the rarity, the size, the place in where the purchase is made (in a supermarket, in a specialized center or online). On average, a ficus bonsai costs around thirty euros, while for an azalea bonsai ten euros more is required; the most economical, on the other hand, are olive bonsai, which are also sold for twelve to fifteen euros.
Of course, when we talk about the cost of bonsai we refer only to the purchase price; but it is evident that the maintenance costs for the plant are much more consistent over time. Bonsai, in fact, require continuous care in relation to pruning, repotting, watering and fertilizing. The major costs, therefore, will concern the purchase of soil, fertilizers, fertilizers and new pots.
Maintenance costs: repottings
Speaking of repottings, they simply relate to changing the vase, which is particularly important for bonsai since they must highlight the aesthetic aspect. It should be noted, moreover, that the size and shape of the vase are clearly related to the size and species of the tree: to provide an indicative estimate, however, it can be pointed out that the height of the vessel must correspond to the diameter of the vessel. trunk near the ground. The best containers available are those in stoneware, which guarantee a particularly convenient price ratio, as well as favoring a discreet transpiration (essential to avoid water stagnation and therefore reduce the risk of rotting). Once you have purchased the vase (at a price not exceeding ten euros if it is stoneware: slightly higher if it is terracotta, and lower if it is plastic), you can start the repotting by placing a grid on the drainage holes, which will help to prevent the soil from escaping, and therefore to create a kind of barrier against animal pests. On the grid, therefore, a layer of soil must be placed, above which the bonsai can be placed, whose root mass will have been reduced. Once the small tree has been buried, the soil should be compressed around the trunk; it may be useful, in some cases, to use tie rods, wires and guardians to make the necessary corrections and make the plant assume the desired shape.
Maintenance costs: the purchase of the soil
As mentioned above, the purchase of soil also affects the maintenance costs of the bonsai. The change of the substrate proves to be indispensable when it, with the passage of time, becomes more and more compact and hard, going to negatively influence the oxygenation of the root system and their irrigation. Not only: the soil, with the passing of the months, becomes increasingly poor in nutrients, and consequently fails to feed the plant. Therefore, it will have to be replaced with a new compound, characterized by a fair percentage of river sand, which will offer the bonsai an excellent drainage. The soil, on the other hand, represents a fundamental element to promote plant growth. A soil for bonsai can not do without, among other things, fine gravel, universal soil and akadama. As regards fine gravel, its purpose is to promote oxygenation and drainage: it constitutes the first layer of the soil, and serves to improve the flow of water. Inside the universal soil, however, there are sand, perlite and sphagnum. If used alone it is rather uncomfortable, for example because it retains water in excessive quantities, but inside a mixture it is useful. Finally, the akadama is nothing but a clay of Japanese origin cooked and produced in a special way for the cultivation of bonsai: it can be easily bought in all garden centers. Before being used it must be sieved, and its functionality is compromised after twenty or twenty-two months from the first use: for this reason, it requires frequent repotting. Of all the elements that make up the bonsai soil, the akadama is undoubtedly the one with a higher price. Of course, each species prefers a different mixture: for example, deciduous trees prefer a soil composed of twenty-five percent sand, twenty-five percent from universal organic soil and fifty percent from akadama, while for conifers the soil should contain sand at thirty percent, universal organic soil at ten percent and akadama at sixty percent. The different composition clearly depends on the different needs of the plants: some species may need more ventilation, and therefore less compact soil; others, on the other hand, have a higher hardness, as they desire a particularly dry environment.
Bonsai cost: Maintenance costs: irrigation and fertilizers
Finally, we must not forget that irrigation also entails significant expenses, even if not incurred, as well as fertilization, which can be implemented, depending on the case, with organic fertilizers or chemical fertilizers, in powder form, with granules or liquids (to mix with the water of the watering).
