Choosing soil with good air permeability and water permeability before planting is beneficial to watering. When the upper layer of the basin soil is completely dry, it should be watered immediately, and the watering should be reduced appropriately in spring and summer to prevent it from growing too high. It doesn't like too wet soil, so it should pay attention to daily watering. Watering should be suspended in rainy days.

Fertilize soil or land

Many people think that fertilization should be controlled to prevent plants from growing too high, but more fertilization should be applied when pruning new buds, and weaker plants should be fertilized before pruning new buds to avoid affecting their germination again.

environment

The sunny environment and good air circulation will also reduce the occurrence of pests and diseases. Simple cold protection should be carried out in winter, but if it is placed indoors, it should be placed in a lower temperature position as far as possible, and it is best to be exposed to the sun.

decrease

Pruning is best carried out in winter, when it will enter a dormant period, and the tree shape can be adjusted appropriately to cut off weak gains and those eroded by pests and diseases. Picking flower buds from March to April every year,

When water and nutrients are right, the environment is wrong and useless, so all aspects must be combined to raise plants well.

Seven tricks for bonsai cultivation of black pine ① More topdressing.

Generally speaking, it is better to plant pine trees with thin soil, and it is necessary to control fertilizer and water as much as possible so that the supply of fertilizer and water can just maintain the minimum survival of black pine. This practice may be effective in avoiding too long pine needles.

In the bud cutting stage, pine trees should be topdressing more. It is foolish to cut off the tender buds of weak saplings, which will hinder the next germination.

Therefore, "topdressing first, then cutting buds".

② Drink plenty of water.

Some people think that watering more will kill pine trees. On the one hand, this misunderstanding is caused by confusing black pine with five needles, on the other hand, it is caused by improper drainage.

As long as the black pine is cultivated with suitable flower soil, it is impossible to die because of too much watering. "Once the topsoil is dry, water it immediately", which is the most basic common sense.

(3) In a well-ventilated and well-lit place.

No matter how you fertilize and water, if the place is dark and ventilated, the seedlings will not grow. Pests and diseases are also the most vulnerable to such weak saplings, so it is necessary to realize that "the key lies in daily management" before disinfection.

(4) inhibiting the vigorous growth of tree buds.

Black pine is a big tree species, and its core grows vigorously, so it is necessary to pick green frequently. Cut the buds? Sparse buds? Adjust the tree type by picking leaves, and pay attention to prevent weak branches from dying. Especially picking leaves, even if you don't cut buds, you should stick to picking leaves all the year round.

⑤ Cut buds and level long leaves.

It is common for someone to cut pine leaves short. This will leave an ugly brown incision. Although this kind of incision will not cause seedling death, it will sometimes cause resin overflow.

In fact, there is nothing wrong with the leaves being too long. Cutting the buds in the second year will flatten the buds. Many people will say that black pine is not easy to handle. I think it may be that everyone finds the secret of this weak bud cutting difficult to understand.

6. Don't forget to layer and cut short.

Seedlings with extremely long stems must be laminated first and then cut short. Even a very thin part, as long as there are two or three branches, it is easy to grow roots.

⑦ Cold and antifreeze in winter.

Large bonsai can be placed outdoors, and miniature bonsai should be protected from wind and frost. Although you can't care too much, antifreeze is good for spring buds.

It is also necessary to understand the one-year growth cycle of black pine. Transplanting, bud cutting, green picking, bud cutting, bud thinning and leaf picking. What do you do in the month?

Maintenance management and maintenance site of black pine bonsai 1. Black pine likes light, and the maintenance place should be sunny and well ventilated. However, small bonsai made by young trees should be properly shaded in hot summer. In Beijing, field growers can spend the winter outdoors. Potters should move indoors in early winter, and black pine can survive the winter safely as long as it is not frozen in the maintenance place. If the temperature is too high, it will be bad for the growth of black pine in the coming year. In late autumn and early winter, black pine and pots can also be buried underground in the leeward and sunny places. The upper mouth of the basin should be lower than the ground. Water it first and fill the pit the next day. The trunk is higher than the ground, so it can also winter outdoors.

2. water. Dry soil is the best way to cultivate black pine bonsai. If you don't do it, water it thoroughly (if there is water leaking from the drainage hole at the bottom of the basin, water it thoroughly). Don't wet the water on the basin soil, it will dry at the bottom, and the roots at the lower part will not get enough water. Especially in summer, the ground temperature is high and there is no water, which is not good for plant growth. Black pine likes humid environment and should be sprayed on the ground, branches and leaves frequently, especially in hot summer, once in the morning and once in the evening.

3. Fertilize. Black pine doesn't like big fertilizer, so it is enough to apply decomposed rare organic liquid fertilizer once a year in spring, summer and autumn. Hypertrophy easily leads to long migration of branches, but the tree shape is not beautiful.

4. Plastic surgery. Every spring, black pine will grow thick and low new buds. When the needle is not unfolded, cut off the new buds according to the needs of modeling. Generally, half of the new buds are cut off to shorten the branches. If the branches don't stretch, all the new buds can be cut off. If you want to change the tree shape and cut off the larger branches, it should be done during the winter dormancy period.

5. Prevent pests and diseases. Black pine diseases mainly include leaf rust, needle drop disease, pine tumor disease and so on. The main pests are scarabs, red spiders and pine caterpillars. Therefore, we should pay attention to timely prevention and control.
