Hydroculture:
Growing bonsai plants in water
According to the Federation of Bonsai Production in Japan, the cultivation of bonsai plants in water is one of the operations that is not without some problems or disturbances, and it is better to conduct it when the plants are young, and they are well-grown and free from disease injuries.
Also, when growing bonsai plants in water, all soil particles attached to the roots must be completely removed, so that they do not cause rotting roots when they remain in the water.

When transferring bonsai plants for cultivation in water, they must be placed in special hydropots, and the best time to perform this process is from March to September.

Of course, a certain number of green and flowering plants are suitable for converting their cultivation from soil to cultivation in water.
problems of growing bonsai plants in water.
When switching from growing bonsai plants from soil to water planting (Soil culture) rosing some Problems , this is because the speed of spreading roots in the soil is much easier than spreading them in water without facing any problems.
The success rate of bonsai plants in mud pellets or mud pellets and pebbles is very high than the success rate of roots in water.
The pot transferred to the plant mechanism must also be clearly larger and without a drainage hole, because the water remaining around the roots for a long time is necessary for the plant.
Pay full attention to the process of changing the water every once in a while and do not leave it for a long time.
Attention must be paid to adding or spraying foliar fertilizers according to the established program
The bonsai plant is also placed in places with a suitable lighting ratio for the plant’s need.
Problems facing bonsai plants:
Problems that make plants sick or tired.
Among the most important problems
encounter bonsai plants are the following.
1- Very weak lighting in a warm place.
2- Exposing shade-loving plants to direct sunlight, as well as placing sun-loving plants in a shady place.
3- The intense sun of the spring season makes the plants as if they were dead.
4-temperature fluctuations.
5- The presence of a hot water basin (exposed to the sun) near the window glass.
6- The presence of a cage of birds or ornamental animals between the window glass and the curtain hanging on it.
7- Very cold or polluted irrigation water.
8- Increasing the amount of basin water in very cold places.
9- Plants are saturated with water, making them affected by the cold weather.
10- The decrease in the percentage of oxygen O2 in the air in places that are not well ventilated, as the lack of oxygen causes weak plants and their lack of good growth.
11- Air pollution with some harmful gases leaking from gas pipelines or ovens or gas resulting from the burning of coal during the preparation of food grilled on charcoal.
12- Placing plants in places with strong air currents that weaken plants very much and may die.
13- That the size of the container in which the plant is placed is very small and not commensurate with the size of the plant in which it is placed.
14- Not protecting bonsai plants from infection with fungal diseases or insect pests, so a preventive program must be developed that is balanced with the type and size of the plants.
15 – All types of bonsai plants are grown in flat dishes or trays of shallow depth with a small amount of soil, and this means that the soil dries quickly and the nutrients are consumed quickly, so the following must be done:
* The soil must be sprayed before irrigation with a light spray of water, otherwise the water when it is added directly (without performing this spraying process) will seep quickly through the cracks in the soil to no avail, sweeping with it part of that soil through the bottom drainage holes, so the volume of that soil will decrease with the passage of time. the time .
* It is preferable to carry out the fertilization process every month, provided that slow-dissolving fertilizers are used, from which nutrients are released in a known amount, which helps to avoid burning the roots of the bonsai and not to precipitate salts in the medium (the pot) in which the plants are located.
* With full attention, fertilization should not be done immediately before flowering, but rather after cycling or after pruning, or when the plants show symptoms of lack of nutrients.
