What to Do When a Ficus Bonsai Drops Its Leaves? A Detailed Guide to Prevention and Treatment

Nursery Stock 0 views
When a newly purchased healthy ficus drops its leaves, it is mostly due to insufficient nutrition and a hidden decline in tree vigor, triggered by sudden changes in its habitat (such as temperature, humidity, light, etc.). If a long-cultivated potted plant drops its leaves, factors such as soil nutrient deficiency, alkalization, or pests and diseases should also be considered. For this situation, we can summarize the prevention and treatment measures as follows: 1. When purchasing, choose a healthy, long-potted plant with spreading leaves, deep green and glossy, and free of pests and diseases on the whole plant, and the growing medium should be loose, fertile, and airy. 2. Place it in a relatively bright indoor spot, with the temperature between 10°C and 30°C and with little fluctuation

When a newly purchased healthy ficus drops its leaves, it is mostly due to insufficient nutrition and a hidden decline in tree vigor, triggered by sudden changes in its habitat (such as temperature, humidity, light, etc.). If a long-cultivated potted plant drops its leaves, factors such as soil nutrient deficiency, alkalization, or pests and diseases should also be considered. For this situation, we can summarize the prevention and treatment measures as follows:

1. When purchasing, choose a healthy, long-potted plant with spreading leaves, deep green and glossy, and free of pests and diseases on the whole plant, and the growing medium should be loose, fertile, and airy.

2. Place it in a relatively bright indoor spot, with the temperature between 10°C and 30°C and with little fluctuation, no lower than 5°C in winter and no higher than 35°C in midsummer, and pay attention to ventilation, frequently misting the leaves, etc. After Grain Rain and before Cold Dew, it can also be kept outdoors, with a little shading in midsummer. Note that in a dry indoor environment, keep it away from heat sources, especially at low temperatures.

3. Apply light fertilizer frequently, mostly applying dilute cake fertilizer water or alum fertilizer water, and irregularly spray 0.3% urea solution, 0.3% potassium dihydrogen phosphate solution, etc. Avoid applying concentrated fertilizer or raw fertilizer.

4. Actively prevent and control pests and diseases. You can drench the roots with 14.5% Duoxiaoling water-soluble powder at 150 to 200 times dilution, or 20% Tubа wettable powder at 500 times dilution, etc., once every 20 days. Apply 3% carbofuran granules to the roots, 5 g to 10 g per plant, once every 20 days to control insect pests. Spray the leaves with 70% thiophanate-methyl wettable powder at 1200 times dilution, etc., to control leaf diseases.

5. Prevent leaf drop. You can spray cytokinin at 50 mg/kg water, 0.01% Fuzi at 300 to 400 times dilution, and other solutions, once every 15 to 20 days. During the vigorous growth periods in spring and autumn, you can also spray 15% paclobutrazol wettable powder at 300 to 500 times dilution once or twice. When the air is dry or there is drought, you can also spray high-lipid film concentrated emulsion at 200 times dilution, etc. Before changing environments or to strengthen tree vigor, you can drench the roots with 5 ppm to 10 ppm ABT No. 3 rooting powder solution.

6. Control leaf drop. Once the ficus drops its leaves, you can spray 95% fangluosu wettable powder at 50000 times dilution, plant cytokinin 0.4% wettable powder at 800 times dilution, etc. Under sufficient fertilizer and water conditions, you can also spray gibberellin at 20 mg/kg water solution to control it, and in severe cases once or twice a week. At the same time, soil, fertilizer, water, and management should also be considered comprehensively, and treatment should be applied according to the specific cause.
