Culture method of banyan bonsai

Banyan bonsai is one of the choices for many flower friends to cultivate green plants in recent years, its shape is simple, desolate and rich style, really people like, simple and tasteful, with high ornamental value. In the bonsai of household plants, it is also more popular because of its evergreen seasons, so let's take a look at the breeding methods of banyan trees.

Culture method of banyan bonsai

1. Lighting: banyan trees belong to subtropical plants. They like sunny, well-ventilated, warm and humid environment. Sexual tolerance to drought, tolerance to semi-overcast. Generally should be placed in the ventilation and light transmission place, there should be a certain space humidity, the sun is not sufficient, ventilation is not smooth, there is no certain space humidity, can make the plant yellow, dry, leading to the occurrence of diseases and insect pests, until death.

2. Watering: the banyan tree is planted in the basin, and if it is not watered for a long time, the plant will wither due to lack of water, so it is necessary to observe in time and water according to the dry and wet condition of the soil to maintain soil moisture. Water until there is water seeping out of the drainage hole at the bottom of the basin, but not half of the water (that is, wet and dry). After watering once, when the soil surface turns white and the surface soil is dry, you should water again, and you must not wait until the basin soil is all dry. In the hot season, you should often spray water to the leaf or the surrounding environment to cool down and increase air humidity. The frequency of watering should be less in winter and spring and more in summer and autumn.

3. Fertilization: banyan trees do not like fertilizer, so they can apply more than 10 grains of compound fertilizer every month. When applying fertilizer, bury the fertilizer in the soil along the edge of the flowerpot and water it immediately after fertilization. The main composition of fertilizer is nitrogen, phosphorus and potassium.

4. Pruning: wild piles become pile scenes, and pruning is a very important process. In the first year, we first cultivate its foundation, nourish its essence, erase only the wrong buds, and wait for the branches to grow thick and lignified in the second year before they can be cut. Give priority to shearing, supplemented by binding, it is appropriate to cut once a year, the strong and vigorous ones can be cut twice, and the forked branches growing from the short branches will be cut again after being strong. Over and over again, if you trim it properly, within four years, a good bonsai will appear in your hands.

The leaves of banyan bonsai turn yellow.

The main results are as follows: 1. Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious change, the branches are small and yellow-green, and the new shoots are not long, indicating that they are overwatered. Remove the flowers from the pot and place them in a ventilated, cool, self-drying soil mass and then put them back into the basin.

2. Dry yellow: the yellow with lack of water is different from the yellow with more water, the yellow with lack of water is withered or dry at the tip or edge of the leaf, and the old leaves wither and fall off from the bottom up, but the growth of the new leaves is relatively normal. Pay attention to watering enough and thoroughly.

3. Burning yellow: strong sunlight shines directly on some shade-loving flowers (such as orchid, peacock taro, hairpin, etc.), which can easily cause withered leaf tips and edges, and yellow spots in the sunny part of the leaves. Just move to the shade.

4. Lack of light: if the leaves are placed in a shady environment for a long time, the leaves can not get enough sunlight to form chlorophyll, and the whole leaves turn yellow and fall off. Supplementary light can avoid the disease.

5. Fat yellow: flowers yellowing caused by too much fertilization or too much concentration, showing dry brown at the tip of new leaves, general leaf thickening and no luster, and concave and convex not stretching, old leaves scorched yellow shedding. Fertilizer should be stopped immediately and some fertilizers should be washed with a large amount of washing.

6. Lack of fertilizer: the lack of fertilizer shows that the color of the tender leaves becomes lighter, yellow or light green, while the old leaves are more normal or gradually change from green to yellow. Check the basin soil, if there is a dry knot phenomenon should change the soil, usually apply thin fertilizer frequently and pour some alum at the right time.

Notes on banyan bonsai

1. Improper watering: the banyan tree must adhere to the principle of not drying and watering thoroughly. The drying here means that the surface of the basin soil is dry, not thoroughly. Of course, even if it is dry, it will not cause great damage to the banyan tree in a short time, because the leaves of the banyan tree are thick and small, and have a certain degree of drought resistance.

2. Improper fertilization: the fertilization of banyan trees should be carried out by applying thin fertilizer frequently to avoid the application of high concentration chemical fertilizer or unfermented mature organic fertilizer, otherwise it will cause fertilizer damage, the light ones will lose their leaves and the heavy ones will die.

3, lack of light: the banyan tree grows well under sufficient light, and the leaf color is greener if it can shade 30-50% of the sun in summer, but it is best not to shade when the temperature is lower than 32 ℃, so as to prevent the leaves from falling off.

4, caused by pests: the main pests caused by fallen leaves in banyan trees are red spiders and shell insects, although there is also a "thrips" harm, it is only rolled leaves to absorb juice, the harm is less than the above two kinds, and thrips are easy to control, only leaves can be removed and destroyed. The individual red spider is relatively small, and the general harmful part is the back of the leaf, which is caused by poor ventilation and dry air. The whole plant can be washed with water and sprayed with special mites, such as mites, acaroid mites and so on. The harmful parts of shell insects are mainly stems and petioles, with different size and color, round and oval in shape, and generally do not move, but they are harmful and need to be prevented and treated in time. They can be wiped clean with a toothbrush or dishcloth, or 0.2% solution of detergent and essential oil can be sprayed, or pesticides such as methamphetamidophos are sprayed with good results.
