What to do if a banyan tree drops leaves
Comprehensive analysis of banyan tree knowledge from the perspective of floral clinics, what to do if a banyan tree drops leaves, let's understand this together next.
Currently, there are mainly two types of banyan trees cultivated by gardening enthusiasts: ginseng banyan and money banyan, both of which can be called banyan trees. Some gardeners find that their banyan trees are dropping leaves and don't know what to do. In fact, it is important to distinguish the situation when a banyan tree drops leaves and not to blindly follow the methods found online.
I. Natural Leaf Drop
Banyan trees naturally shed leaves at the end of autumn each year and will grow new leaves the following year. During the leaf shedding period, it is important to reduce watering to prevent root rot during winter.
II. Other Artificial Reasons
Many gardeners are looking for reasons, but I can't see their banyan trees and I don't know how they care for them, so I can't tell them why their banyan trees are dropping leaves or how to solve the problem. Gardeners need to investigate each of the reasons I mention below to find the cause of the problem.
1. Improper watering: When watering banyan trees, it is essential to adhere to the principle of "not watering until dry, and watering thoroughly when watering." The dryness here refers to the surface of the potting soil being dry, not the soil being completely dry. Even if it is completely dry, it will not cause significant harm to the banyan tree in a short time because the leaves are thick and small, and the tree has a certain drought tolerance.
2. Improper fertilization: Fertilizing banyan trees requires frequent application of dilute fertilizers, avoiding the use of high-concentration chemical fertilizers or unfermented organic fertilizers, as this can cause fertilizer damage, resulting in leaf drop or even death.
3. Insufficient light: Banyan trees grow well in environments with sufficient light. If they can be shaded by 30-50% during the high-temperature summer months, the leaves will appear even greener. However, it is best not to shade them when the temperature is below 32°C to prevent leaf drop.
4. Pest infestation: The main pests that cause leaf drop in banyan trees are red spiders and scale insects. Although "thrips" can also cause harm, they only curl the leaves and absorb sap, making their damage less severe than the other two and easier to control. Simply remove and destroy the curled leaves. Red spiders are relatively small and usually affect the back of the leaves, caused by poor ventilation and dry air. You can wash the entire plant with a large amount of water and then spray miticides such as Mitaclean or Cridemite. Scale insects are commonly found on stems and petioles, varying in size and color, with shapes including circular and elliptical. They generally do not move but are quite harmful and require timely control. They can be removed with a toothbrush or cloth, or sprayed with a 0.2% solution of laundry detergent or eucalyptus oil, or treated with pesticides such as cypermethrin, all of which are effective.
5. If "DDVP" is sprayed in the environment where the banyan tree is growing, it can also cause leaf drop, especially in the case of money banyan trees, which are particularly sensitive to DDVP.
