Pine tree maintenance method, how to maintain pine bonsai

Planting pine trees need to choose a deep soil layer, soft, easy to drain and have a certain fertility of the soil, it is recommended to turn the ground once before planting, and apply bottom fertilizer to improve fertility. The seedlings we plant are generally one or two years old, and we need to carry soil balls when digging, which can protect the root system well. When planting, dig a pit of the right size, then put a soil ball into the pit, fill it with soil and compact the soil.

After planting, it is watered in time and permeable, so that the survival rate of planting is relatively high.

Methods of maintaining pine bonsai.

1. Avoid stagnant water.

The pine tree is a typical drought-tolerant and hard-working plant, and it can live well even if we don't water it for a long time. But if you water the pine tree too much and there is stagnant water, it will cause the pine tree to die. In spring and autumn, you need to water once every 3 to 4 days, once every 1 to 2 days in summer, and in winter, you need to keep the potting soil slightly moist, with an average of 1 water per week.

Don't get standing water in any season.

2. Sufficient light.

Regarding how to maintain pine bonsai, many people will forget about the light. In fact, the light requirements of pine trees are different throughout the year. The sun is very gentle in spring, autumn and winter, and it can be placed in a place where the sun shines for 3 hours a day, and it can also be sunshine in summer, but it must be in moderation, and it is necessary to avoid the scorching sun at noon.

3. Apply a small amount of fertilizer.

The amount of fertilizer applied to pine bonsai must be small, but at least once a year during the spring growth period, homemade organic fertilizer, bone meal or eggshell powder is fine, and a light fertilizer is added from September to October to ensure the growth of pine trees. At other times, be careful not to fertilize, especially in winter.

4. Pruning. The most important thing as a bonsai is pruning, and the pine tree after pruning can be regarded as a bonsai rather than a bonsai. There are different pruning requirements at different times, January is the best time to shape and wrap the aluminium wire, and July and August when the new pine needles have grown and the old shoots need to be cut off.

In September and November, use tweezers to remove the yellowing needles, and finally in December you can prune.

5. Change the pot. Many people will think that pine bonsai does not need to be repotted, but in fact, every plant needs to be repotted when it is artificially planted, and it is just a matter of time. Pine bonsai should be repotted every 3 to 4 years, and the best time is from September to October.

If the pot does not bear it for a long time, the soil will lose nutrients and prevent the plant from growing.

Pine bonsai pruning method.

1. Cut off the excess branches.

If bonsai maintenance is the foundation, then pruning is sublimation. Pruning bonsai is its essence, so as to remove its dross and leave its essence. The most basic thing to do is to cut off the excess branches, those perverse pine branches and diseased branches are the excess branches that need to be cut off.

It is good to have a few well-grown main branches, usually 4 to 5 branches.

2. Adjust the main branch.

If you've already removed the extra branches, it's time to start pruning the main branches. The main pruning follows its growth direction, as long as the main branch is adjusted in time to prevent it from growing "off". As soon as there are signs of growth, cut it off in time, prune it a few times, and it will grow in the direction you want.

3. Post-pruning.

While adjusting the main branches, you must pay attention to pruning them in time as long as you see the cluttered branches and buds growing. This is a relatively long and boring work, but only in the later stage of continuous refinement will the modeling be slowly completed. However, it is important not to regenerate long-term pruning, which is not to make it sprout after all.

1. Light. Pine bonsai is not very sun-loving, although it does not need all-day sunshine, but it is also necessary to maintain two to three hours of light a day, and in summer, the weather is hot and the sun is scorching, and it is necessary to shade it at noon.

2. Stagnant water. Pine bonsai water accumulation is fatal to pine bonsai, first of all, the pine bonsai soil will lose its air permeability, and then the roots will rot, so that they can not absorb water, resulting in the branches and leaves of the plant dry and yellow, and in severe cases, the pine tree will die. Therefore, when watering pine bonsai, control the amount and pay attention to the dryness and humidity of the potting soil.

3. Fertilization. The pine tree itself does not have a very high demand for fertilizer, if you want to make your pine bonsai grow faster, you need to apply some additional fertilizer, but the fertilizer must not be excessive, it is recommended to fertilize twice a year from August to October. Most people fertilize it aggressively in order to make it grow quickly, which is counterproductive.

4. Change the pot. It is also very important to change the pot if you want to raise a good pine bonsai, of course, when you change the pot, you will change the soil, and the interval between the pot changes is about every 3 to 4 years. Although repotting is good for pine bonsai growth, it should not be too frequent, as frequent repotting will cause it to die.

1. Substrate selection: its requirements for soil are not strict, the adaptability is strong, and it can tolerate barrenness, so it is best to choose loose and fertile sandy loam with good drainage and acidity.

2. Light management: most of them like light, weak negative resistance, if it is in a dark environment for a long time, it is easy to lead to sparse crowns, so it should be given full sunlight when breeding, which is conducive to its strong growth.

3. Water management: its leaves are narrow and the cuticle is developed, with a xerophytic structure, so it has strong drought tolerance, can tolerate water shortage without injury, and can grow in a shallow and stony arid environment, too much water content in the soil is not conducive to its growth, it is necessary to pay attention to drainage, avoid water and waterlogging.

4. Temperature management: It is a well-known pioneer tree species, which has strong adaptability to environmental temperature, is cold-resistant and heat-resistant, and can thrive in both high and low temperature environments.

1. Propagation method: It can be propagated by sowing method or cuttings. Among them, the sowing method is to promote the germination of seeds in the sand in winter, cover the grass curtain on the sand pile, pay attention to keeping warm and frostproof, keep the environment ventilated, and sow seeds when there are about half of the cracks in the seeds in the next year.

2. Transplantation method: its transplantation method is different because of different seedling species, among which the container seedling can protect the root system of the plant from being damaged during the transplantation process because of the mound, so the survival rate is higher, and the root system of the bare root seedling is relatively easy to be damaged, and it is necessary to pay attention to protecting the root system during transplantation.

1. Yellowing of leaves: If the needles are dehydrated and yellowed, we must pay attention to check whether there are signs of parasitism of the beetle, and once it is found, it is necessary to manually cut down and remove the diseased trees in time to prevent the spread of the beetle and harm the trees.

2. Pests: Its more common insect pests include red spiders, large moths, red wax scale insects, etc., once found, they should be sprayed with insecticides in time.

1. Meaning: Its tree posture is vigorous and magnificent, the tree shape is tall and long-lived, with a long history and culture, it is regarded as a symbol of firmness, chastity and longevity, and plum, bamboo and called "three friends of the year", with the courage to overcome adversity and difficulties of the tenacious spirit.

2. Toxicity: It is not toxic, pine is generally used as an industrial raw material, of which pine resin can be used to extract rosin, and some varieties of seeds and pine needles can also be used as medicine, which is of great practical value.
