The Hibiscus bonsai originates in the tropical areas and in the temperate climate zone. We can also find it in our country in the Syriacus variant, which presents itself with leaves of a beautiful shining green and with multicolored blooms.
Like many plant species, Hibiscus Bonsai is also a deciduous plant. What does it mean? It means that throughout the cold period, your bonsai will have the bare appearance of those trees that you see in winter, but when the warm weather arrives, it will bloom in a wonderful way giving you a priceless crown. Cultivating it carefully, waiting for this moment will not make you regret choosing it.
The Hibiscus bonsai should be placed for the duration of the year in a bright and sunny place. You will only have to pay close attention to protecting it, during extremely cold or extremely hot seasons, from the effects of frost or drought. Despite this, the Hibiscus bonsai is a plant particularly resistant to such conditions.
Although the hibiscus bonsai is a deciduous plant, it should be watered throughout the year, even during the so-called rest period. Watering must be well proportioned by calibrating them to the needs of the plant: based on the climate of the period, the capacity of the container, the soil used to cultivate it, and the health conditions of the bonsai.
Pay particular attention, during the growing season, in increasing the frequency and intensity of watering. In contrast, during rest they will be decreased. So make sure that in summer the plant is well humidified and moisturized in order to preserve it from the dangerous effect of solar heat, while in winter it will be enough - always according to the health conditions of your plants - to water it even just a couple of times a month. When the mid-seasons arrive, sprinkle your Hibiscus bonsai three times each week using an onion waterer: pour the water in minimal quantities, wait for the soil to absorb it properly. Then continue. Make sure, however, that the drainage of the soil is good, well ventilated and never stagnant because the Hibiscus bonsai does not go very well with stagnation.
In spring and late autumn you can proceed with the fertilization of your Hibiscus bonsai.
Be careful not to fertilize it in the summer - or in extraordinarily dry periods - and never after repotting operations.
During the growing season, on the other hand, it is necessary to apply frequent fertilizers because, as long as the vessel can be large, it will in any case host an insufficient amount of soil that will not be able to satisfy the nutritional needs of your bonsai and its root system. .
Then proceed as follows: water the substratum well and each month let the liquid fertilizer dissolve in water in varying proportions depending on the state of health of the plant, the amount of soil and drainage capacity. Remember that, in addition to the more rapid and convenient liquid fertilizer, it will be possible to use solid granular fertilizer, which will be absorbed more slowly.
PRUNING AND MAINTENANCE
If you intend to make your bonsai perfect, you will naturally not be able to do without pruning.
With the training pruning, you will have the chance to shape the bonsai according to your taste (attention though that your aesthetic sense must stop where the plant would suffer).
More generally, the training pruning will be carried out in the spring period. Subsequently, when the plant will enter in full vegetative period, it will be necessary to carry out the topping and the defoliation. In the latter case, it is advisable not to intervene in a compulsory manner, but always leave at least two or three leaves, among the most minute.
Of course your Ibisco bonsai will need all your care and attention to be able to grow at its best. Carry out the maintenance operations so as not to frustrate the efforts you have previously made: remove the irregular branches, those that have become dry or damaged. Carry out all the operations using the most suitable instruments, available in specialized shops in different colors, price ranges and, of course, quality. Among the most common tools we find the scissors for leaves, those for the roots and particular shears to be used with the woody parts and branches.

The Hibiscus bonsai repotting operation is a practice that requires attention and care. You will have to repot the hibiscus bonsai during the resting period (in normal conditions, the ideal resting period for repotting bonsai is to be understood either in late autumn or early spring).
Replace the old vase with a new vase and change the soil with fresh soil. Remove the most woody roots with particular delicacy and leave the most tender and fresh ones.
Of course, the repotting operations must be carried out with a certain frequency during the first years of the plant's life, while when it has reached adulthood the bonsai can be repotted even once every seven years.
