What are the breeding methods and precautions in banyan bonsai?

1. Soil selection for farming in banyan bonsai

banyan bonsai likes sunny, well-ventilated, warm and humid environment. When the weather is hot in summer, it is necessary to shade properly and often sprinkle water on the ground to maintain a certain humidity in the microclimate. In the north, in late autumn or early winter, banyan bonsai bonsai should be moved indoors for the winter.

2. Fertilization method of banyan bonsai culture

In the growing season, the decomposed thin organic liquid fertilizer is applied once a month, and the "alum fertilizer water" is applied once a year in May and August. Don't fertilize too much in banyan bonsai. Fat branches are long in vain, but leaves are not beautiful when they are enlarged. Don't fertilize in hot summer and winter.

Because of its rapid growth, banyan bonsai can apply topdressing outside the roots once a day after normal growth, using decomposed human and animal urine or cooked fertilizer as topdressing, and applying base fertilizer when changing pots. Sufficient fertilizer can make the trunk grow thick. If the pot soil is fertile, there is no need for topdressing, and nutrient solution can be sprayed on the leaves during the growth period of summer and autumn to make the branches and leaves dense and green, giving people a beautiful feeling.

3. Watering method of banyan bonsai culture

banyan bonsai is a tropical plant, which likes big water and big fertilizer. It has strong adaptability, and can grow in crevices and water. However, after growing up, banyan bonsai should keep the basin soil moist, and it is advisable to water it twice a day in summer.

banyan bonsai likes humidity, so it should be watered frequently during the growing period to keep the soil in a certain humidity, but there should be no water in the basin. In winter, the temperature is low and the water evaporation is less, so water should be less appropriately. Banyan bonsai likes to be wet, so it is necessary to keep the soil moist in the growing season. In summer, besides watering the basin, it is also necessary to sprinkle water on the ground frequently to keep the local microclimate moist. But there should be no water in the basin. Water less in winter, and you don't need to water the pot soil when it is wet.

4. Lighting requirements for aquaculture in banyan bonsai

banyan bonsai likes sunny, warm, humid and ventilated places, and can be properly shaded when the weather is hot in summer. In the northern winter, it should be moved indoors for wintering, and the room temperature is about 8℃. Banyan bonsai is not afraid of sunshine, but also quite resistant to shade. If it is kept indoors for a long time, its leaves will not turn yellow, so it should be exposed to more sunshine in winter.

5. The modeling method of bonsai cultivated in banyan bonsai

Because of its abundant air roots, banyan bonsai is suitable to be a kind of bonsai with many chiba leaves. When making these two kinds of bonsai, first cultivate their roots and nourish their essence in the first year, and then raise their roots and replace them with shallow pots after they grow vigorously.

banyan bonsai can be used as a stone-attached bonsai because of its fast growth and developed roots. Before planting, the trees are tied into curved shapes with metal wires, and planted obliquely in soil pots. After 2-3 months of cultivation, the air roots increase and the crown is shaped. Then, the saplings are taken out, the cultivated soil is removed, and the saplings are attached to the selected stones. This inch should pay attention to the fact that banyan bonsai and Panzha Tree Stone have the same potential, and the roots should be embedded in the crevices of the stone as much as possible. Wrap the roots tightly with cotton strips or metal wires and put them in a tall big pot for cultivation. Bonsai with stones can be made into stone-holding, stone-piercing, stone-sticking and other forms according to the tree potential.

6. Pot-turning method for banyan bonsai culture

Pots of banyan bonsai bonsai with short tree age should be turned once every two years, and pots of old pile bonsai should be turned once every three to four years, preferably from late April to early May, and it is not easy to turn pots in winter. Remove 1/2 of the old pot soil, cut off dead roots, short roots, short roots, and thin some over-dense roots, add some new fertile culture soil, and plant banyan bonsai well. Sometimes the pot-turning machine is used to change the shape of trees, or to change pots with higher appreciation value.

7. Matters needing attention in banyan bonsai culture

(1) Pruning and shaping in banyan bonsai are mostly carried out in dormant period, and the sap flows quickly in growing period, and more white sticky sap flows out after pruning, which is unfavorable to plant growth. Climbing can be carried out in all seasons in banyan bonsai. When climbing in the growing season, be careful not to damage the bark to avoid the outflow of sap.

(2) During the growing season in banyan bonsai, the soil in the basin should always be moist, and special attention should be paid to raising the air humidity. In dry air, the leaves will burn, turn yellow and gradually fall off.

(3) Indoor furnishings banyan bonsai should be placed in a ventilated place with bright scattered light. Outdoor furnishings should be properly shaded in spring and summer, and more sunshine can be seen in winter. In winter, the room temperature should be kept at 5-8℃, the pot soil should be prevented from being too dry and wet, and the leaves should be cleaned once a week with warm water close to room temperature to make the leaves clean and bright green. If the room temperature is too high in winter, you should open the window for ventilation, otherwise a lot of leaves will fall after leaving the room in the spring next year.

8. Propagation method of banyan bonsai culture

(1) Cutting propagation in banyan bonsai

Select thick branches for cutting and planting, insert them into loose, breathable and acidic mixed soil of stone powder, river sand and cinder, and the depth is about 3 cm. After watering, turn them to a cool and leeward place for maintenance. The ground plants are shaded with a cover. If the temperature is low when cutting in early spring, it is best to bag with film to keep the temperature constant and facilitate survival. Usually, the soil should be kept moist and free of water. Banyan bonsai takes root after the bud. When the bud grows to 5-6 cm, gradually let the pile material see the sun, and then transplant it into the pot after the bud and root grow strong.

(2) banyan bonsai's propagation by dividing plants

banyan bonsai has the characteristics of quick rooting and sprouting. You can choose the stumps with tortuous trunks and unique trees, which are suitable for bonsai, and transplant them from each plant, keeping as many air roots as possible. After one to two years of careful cultivation, the air roots can be cultivated and shaped according to the author's idea.

9. Prevention and control methods of pests and diseases in banyan bonsai

There are fewer pests and diseases in banyan bonsai, and poor ventilation and light transmission or excessive application of nitrogen fertilizer may cause powdery mildew, which can be sprayed with 5 times of 5% carbendazim wettable powder. Insects occasionally occur, and 8% dichlorvos EC can be sprayed 15 times. Or after a proper amount of carbofuran particles are shallowly buried in the basin soil, the water penetration effect is quick.
