What are the requirements for pine bonsai soil? Do pine bonsai need to be watered every day?

Pine trees are very vigorous and ornamental plants. Pine trees made into bonsai and placed at home are also very beautiful. In particular, they can be trimmed to present different shapes. So what are the requirements for the planting soil of pine bonsai?

What are the soil requirements for pine bonsai?

For bonsai, when we transplant it into a pot, the loam in the pot not only stabilizes the plant, retains moisture and provides nutrients, but also the root system's absorption of oxygen cannot be ignored. The fertility of the soil, water permeability, looseness and fertilizer retention effect cannot be ignored. At the same time, pine trees also have certain requirements for the acidity and alkalinity of the soil. Loam that is too alkaline is not suitable for its growth. Acidic loam with a pH value between 5 and 6 is more suitable.

You can go to the wild woods to collect some shallow loam and pine needles as a supplement, and mix it with some decomposed humus and fine river sand. On the eve of potting, it is better to add some decomposed cake fertilizer or organic fertilizer. Finally, cover the upper layer of the loam with fresh moss to achieve the function of retaining fertilizer, water and moisture, comfortable and breathable, and also give people a beautiful effect of green.

The environment for maintaining pine trees requires dry pine and wet cypress. If the tree is dry for too long, it is very easy to form a board. Especially when using a pot that is too deep to plant pine trees, once a board appears, the water permeability will deteriorate and the drainage performance will also decrease accordingly. If there is too little watering, the water will not penetrate into the bottom and the roots cannot absorb it. If there is too much watering, water will easily accumulate, resulting in excessive internal humidity, which will easily breed bacteria.

Therefore, in the process of maintaining pine trees, once you find that there is a knotting problem, you must help loosen the soil in time. During the loosening process, you can add some decomposed organic fertilizer, and then water it thoroughly until clear water flows out from the bottom.

Do bonsai pine trees need to be watered every day?

When watering pine bonsai, the general principle is to ensure that there is no water accumulation in the potting soil, and secondly to ensure that the pine tree does not lose water. It is recommended to water it twice a day or once every two days. This cannot be determined based on time, but must be determined by climatic conditions: temperature or humidity, wind speed, and the specific dryness and wetness of the potting soil.

To ensure that the bonsai tree does not accumulate water, there must be well-drained soil. We usually mix leaf mold with river sand, which contains both organic nutrients and good drainage.

When watering pine bonsai, I usually look at the surface of the potting soil. If the surface of the potting soil turns white, then you can water it. This is related to the ratio of organic matter and river sand in the potting soil. If the potting soil contains more organic matter and the water evaporates slowly, even if the surface of the potting soil turns white, the pot is still relatively moist. You can delay the watering time, or insert your fingers into the potting soil to feel the dryness and wetness of the potting soil. Don't water too much, as excessive watering can easily cause root rot, which will cause great damage to the pine tree. Also, don't let the potting soil lack water for a long time, as lack of water can easily cause yellow leaves.

Water slowly to allow the water to penetrate evenly until water flows out from the bottom of the pot.

What is the most suitable soil humidity for pine bonsai?

Pine plants are positive tree species that prefer dryness and dislike moisture. They are suitable for an environment with plenty of sunlight, moist and ventilated environment. Their requirements for potting soil humidity are usually best when the moisture content of the potting soil reaches 8%-15%. If the moisture content exceeds 20%, the roots will be suffocated. Long-term excessive moisture will lead to poor plant growth, and in severe cases it will cause root rot, leading to the death of the entire plant.

However, this is only an approximate data. If you want the pine bonsai to grow healthily, reasonable watering is only one of the factors. There are also reasonable pot soil configuration, suitable maintenance place, etc. These are all important factors that restrict the healthy growth of pine bonsai plants.
