Banyan likes outdoor, hair dryer and sunshine bath. There should be plenty of light, preferably a little sunshine for a while, in a ventilated place, not in the corner of the bedroom, and don't let the air conditioner blow directly at it. Acidic soil is a non-cold-tolerant plant. In northern China, greenhouses are generally used for maintenance and management in winter. In fact, the easiest way to raise banyan trees is to dry them thoroughly and water them thoroughly. Fertilize once or twice a year. Although you like applying fertilizer, if you want to cultivate a compact tree, you'd better apply less fertilizer. However, if it is a banyan tree that mainly looks at leaves, such as Ficus pendula and Ficus jinye, it is best to apply less fertilizer and keep the soil moist, so that it will grow vigorously, with large oily green leaves and good ornamental value. Banyan bonsai Conservation: Watering is one of the most important and commonly used measures in banyan bonsai management. Banyan trees are planted in pots, whether deep or shallow, the soil is always limited and the water content is limited. If you don't water for a long time, plants will wither because of lack of water. Therefore, it is necessary to observe in time, water according to the dry and wet conditions of the soil, and keep the soil moisture. Of course, watering should not be excessive. If you water too much, the soil in the flowerpot will be too wet for a long time. At the same time, the amount of watering depends on the change of season and weather. Generally speaking, in summer or drought, it is best to water it once in the morning and evening, once every day or every other day in spring and autumn, and once in the morning and evening when the stump germinates in spring. In rainy season or rainy day, you don't need to water, but also pay attention to drainage. Sandy soil can be watered more and cohesive soil less. Generally speaking, water can be sprayed on leaves or poured on roots. Users in banyan bonsai: The cultivation soil with low requirements should be loose and transparent, such as cow dung, sawdust, cinder, etc., moist, breathable and fertile. The soil in the stump bonsai basin is limited, so the nutrients are limited, so we should pay attention to the supplement of fertilizer. Stump bonsai should not be fertilized too much and too frequently because of its artistic characteristics of seeing the big from the small. It is necessary to master the contents and types of fertilization and grasp the fertilization season. The three elements of plant growth nutrients are nitrogen, phosphorus and potassium fertilizer, and nitrogen fertilizer can promote the growth of branches and leaves of stumps. Phosphorus fertilizer can promote the formation of flowers and fruits. Potassium fertilizer can promote the growth of stems and roots, so the choice of fertilizer should be based on the type of stump and its growth trend. To make the stump flourish, you can apply more nitrogen fertilizer; If the stump needs more flowers and fruits, the content of phosphate fertilizer can be increased; Strong roots are needed, and more potassium fertilizer can be applied when it is developed. Fertilization methods are generally divided into delayed fertilization and rapid fertilization. Slow-release fertilization is generally to pulverize organic fertilizer and mix it into soil according to a certain proportion after decomposition. When changing the soil, mix it into the pot and let it provide nutrients slowly. Quick-acting fertilization is to dilute organic fertilizer or chemical fertilizer and apply fertilizer according to the seasonal growth needs of stumps. But it should be noted that it should not be too thick. The newly planted stump is not suitable for this kind of fertilization. Fertilization in rainy days will lead to the loss of fertilizer efficiency and the effect is not good. The manicured bonsai trees are still growing. If it is allowed to grow naturally without restraint, it will inevitably affect the shape of the tree and lose its artistic value. Therefore, timely pruning, long skill and short cutting, and close skill thinning are needed to maintain beautiful tree posture and appropriate proportion.
