How to maintain pine bonsai
Pine bonsai needs to be turned over every 3-4 years, and it should not be watered excessively every time. Slow-release fertilizer is applied once a month in spring and autumn every year to give pine bonsai enough sunshine and maintain its good growth environment. In spring, you can also trim and shape, do a good job in pest control, and grow vigorously through high-pressure propagation and cutting propagation.

1, turn over the basin to change the soil

As for the problem of how to maintain pine bonsai, it is generally necessary to turn over the pots and change the soil in 3-4 years, which requires loose soil, strong ventilation and drainage and high fertility. Potted pine trees can be planted with humus soil. Don't hurt the roots of pine trees when turning over the pots and changing the soil, so as not to affect the normal growth of pine trees.

2. Proper watering of pine trees is a very drought-tolerant plant. When we potted pine trees, we don't need to water them too often to avoid water accumulation, rotten roots and yellowing of branches and leaves, which will reduce the ornamental value. We can usually water them once a week. When the temperature is too high, we can spray water on the leaves, especially in winter.

3. Rational fertilization

Generally speaking, pine trees have strong adaptability to the environment and can grow normally without fertilization. However, pine bonsai can grow more ornamental if fertilization is reasonable. Generally, slow-release fertilizer or organic fertilizer can be applied once a month in spring and autumn.

4. Pine bonsai with sufficient light can withstand high temperature. Usually, it is best to keep it in a sunny place, so that the pine bonsai can carry out photosynthesis in the sun, which can not only improve the air quality, but also make the bonsai more ornamental. However, direct sunlight should be avoided in summer.

5. Dressing and shaping

Although the growth of pine bonsai is slow, it needs pruning every spring. The lateral branches, old branches and diseased branches of pine trees can be pruned according to their favorite shapes, which is not only beneficial to the growth of pine bonsai, but also can increase the ornamental value of potted plants.

6, pest control In the process of maintaining pine bonsai in peacetime, it is also vulnerable to pests and diseases, which makes the leaves lose color and may even cause pine bonsai to wither and die. It is best to clean up weeds regularly and put potted plants in a well-ventilated and sunny place. Just cut off the diseased leaves in time.

7. Breeding method (1) High pressure breeding

High pressure propagation is the most common method in bonsai. Every spring, you can wrap the strong branches of aluminum wire into two sections with aluminum wire, and then gently cut them with a circle of scissors to peel them off. It is necessary to apply rooting powder to the peeled parts, and after a while, buds will grow, so they can be planted separately in the soil.

(2) Cutting propagation

Pruned branches can be kept every time. Select branches that have been strong for more than one year, apply rooting powder to the wound, or soak the branches in rooting water for about 10 minute, then insert the treated branches into the soil, compact the soil to keep the humidity, and then conduct normal maintenance after the branches take root and sprout.
