Nowadays, many friends enjoy cultivating banyan tree盆景 because of their beautiful shapes, which are very appealing among many plants. However, many people do not know how to care for banyan trees, and some encounter difficulties in growing them, which lead to their death. Banyan tree enthusiasts often face the problem of leaf drop during cultivation and find it difficult to figure out how to deal with it. Here we summarize the reasons and solutions for this problem.
The reasons for the banyan tree leaf drop might be:
1. If a healthy banyan tree recently purchased drops leaves, it is mostly due to insufficient nutrition, a weakened tree vigor, and sudden changes in the living environment (such as temperature, humidity, and sunlight), especially the drastic changes in environmental humidity, which can directly cause a large number of leaves to fall off within a short period.
2. If a long-cultivated banyan tree drops leaves, it should also consider factors such as soil lacking fertilizer, alkalization, or pests and diseases.
Solutions:
1. When purchasing, choose a healthy, long-standing pot with fully expanded, dark green, and shiny leaves, free from pests and diseases, and the cultivation soil should be loose, fertile, and breathable.
2. Place it in a relatively bright room with a temperature between 10℃ and 30℃ and little variation in temperature, not lower than 5℃ in winter and not higher than 35℃ in the summer, and ensure ventilation. Often spray water on the leaves. After Guyu and before Hanlu, it can also be placed outdoors for cultivation, with slight shading during the summer. Pay attention to keeping it away from heat sources in dry rooms, especially at low temperatures.
3. Apply thin fertilizer frequently, mainly dilute cake fertilizer water or alum fertilizer water, and occasionally spray 0.3% urea water, 0.3% potassium dihydrogen phosphate solution, etc., and avoid applying thick fertilizers or raw fertilizers.
4. Actively prevent and treat pests and diseases. You can use Multi-effect Spirit 14.5% water-soluble powder at 150 to 200 times the concentration or 20% soil霸 wettable powder at 500 times the concentration to water the roots every 20 days. Apply 3% furan丹 granular agent, 5 to 10 grams per plant, every 20 days to control pests. Spray 70% methylethylthioctyl tin wettable powder at 1200 times the concentration to prevent and treat foliar diseases.
5. Prevent leaf drop. You can spray cytokinin at 50 mg/kg of water, 0.01% Fuzi 300 to 400 times the concentration, etc., every 15 to 20 days. During the vigorous growth periods of spring and autumn, you can also spray 15% Multi-effect唑 wettable powder at 300 to 500 times the concentration once or twice. In dry or drought conditions, you can also spray a high-fat emulsion concentrate at 200 times the concentration. Before changing the environment or to strengthen the tree vigor, you can water the roots with 5ppm to 10ppm ABT3 root growth hormone solution.
6. Control leaf drop. Once the banyan tree drops leaves, you can spray 95% anti-abortion factor wettable powder at 50000 times the concentration, plant cytokinin 0.4% wettable powder at 800 times the concentration, etc. In conditions of sufficient fertilizer and water, you can also spray gibberellin at 20 mg/kg of water to control it, once or twice a week. At the same time, comprehensive consideration should be given to soil, fertilizer, water, and management, and symptomatic treatment should be applied.
