2. Watering is one of the most important and common management measures in banyan bonsai. 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 to replenish water, the plants will wither due to lack of water, so you should observe them in time, water them according to their soil dryness and wetness, and keep the soil moisture. Of course, watering should not be excessive. If you water too much, the pot soil will be too wet for a long time, which will easily lead to hypoxia and rot of the root system. At the same time, the amount of watering depends on the change of season and the cold and warm 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. Watering can be done by spraying water on leaves or irrigating roots. Generally the two are combined. First, spray water on the leaves, and then thoroughly irrigate the roots. Be careful not to pour "half water" to make the basin surface dry and wet, and don't spray too much water on the leaves, which will easily lead to too many branches and leaves. Family planting in the north should often spray foliar water to increase air humidity.
3. The middle basin soil in banyan bonsai is limited, so we should also pay attention to the supplement of fertilizer. During the growth period of banyan trees in summer and autumn, apply fertilizer once a month to the decomposed cakes, and apply less or no fertilizer in winter. In addition, when changing pots every two years, organic fertilizer will be crushed and decomposed, and then mixed into pots according to a certain proportion to provide nutrition slowly. Quick-acting fertilization is to dilute organic fertilizer or chemical fertilizer, and apply fertilizer according to the seasonal growth needs of stumps, but be careful not to be too thick. Newly planted stumps are not suitable for fertilization in this way. Fertilization in rainy days will lead to the loss of fertilizer efficiency and the effect is not good.
4. It is best to change pots in early spring or late autumn during the dormancy period of banyan trees, and trim the roots that are too dense at the same time. Banyan trees are resistant to pruning, strong in germination and fast in growth. In addition to pruning in early spring, new branches and long branches should also be pruned according to the modeling requirements in normal maintenance to maintain the beauty of the tree and improve its ornamental value.
5. In addition, the growth temperature difference in banyan bonsai should not be too large. When the temperature difference is 10 degree, it is easy to cause the death of fallen leaves. The roots of banyan trees are also prone to root rot or nodule disease caused by various bacteria and fungi. At ordinary times, we should slowly dig up the soil and check the roots without damaging the roots, and pay due attention to spraying drugs for prevention and control. ?
