A bonsai needs water to dissolve and transport nutrients, then get those substances to the organs that need to use them further, to maintain cell division and to make biological reactions possible. Thus, it is imperative for you to understand the watering of the bonsai. Keep reading and see 6 essential rules for watering the bonsai, only the top need to know ones.
Thus, there is a balance between the amount of water that is absorbed and the which is eliminated. When this quantity is not equal, the plant will dry up and if this condition is maintained for a longer period of time, at some point it will die.
This does not only depend on the amount of water that is in the ground, but it is also influenced by temperature, exposure to sunlight, air humidity in the room, air movements and the ability to adapt the bonsai.
If it becomes too wet, it will reach the stage where the soil will not be sufficiently ventilated and the soil temperature will decrease as a result of the low temperature of the water that is excreted through perspiration.
The growth and development of the plant will also suffer under these circumstances. All of these things will result in the death of the roots and the slowing down of the growth process, and then the death of the whole plant.
The most important rules for watering the bonsai
1. The bonsai should be examined once a day.
2. The soil should never be allowed to dry completely.
3. When the soil begins to dry (you will be able to recognize this by its color), the plant must be watered.
4. Watering the bonsai with cold water is not beneficial.
The water must have room temperature. The roots of many tropical bonsai are very sensitive to low temperatures and die already at temperatures below 15°C. You must be careful to ensure that the water temperature is particularly suitable in the winter.
5. Do not use hard water. The salt in the hard water increases the salt content of the soil. The soil’s reaction can be changed by the calcium content of the water, thus contributing to the deposition of nutrients.
The degree of water hardness used should not exceed 12°DH (between 8 and 12 means water hardness is medium). Water that has too much hardness can be softened by using tablets that exist in specialized stores. If you have the opportunity to collect rainwater, you should use it.
6. Bonsai have a relatively small edge where watering can be done, and therefore you need to act with care when you water the plant, so there is no risk of the soil going over the edges of the pot.
If the ground is very dry, the pot will be placed in another container with water. It must be filled up to the half of the container in which the plant is based.
The container will be immersed halfway into the water until the soil has absorbed all the necessary water. This can be noticed by the fact that there are no bubbles of air that rise to the surface of the amount of water left in the second container.
