How to prevent and treat the defoliation of banyan tree bonsai
Today's introduction to the making of banyan tree bonsai, focusing on how to prevent and treat the defoliation of banyan tree bonsai. Next, the editor of this site will introduce to everyone.
How to prevent and treat the defoliation of banyan tree bonsai? For the prevention and treatment of this situation, we can summarize six points to prevent and treat the defoliation of banyan tree bonsai:
1. When purchasing, choose a healthy, long-standing pot with spreading, dark green, and shiny leaves, and free from diseases and pests, with loose, fertile, and breathable soil.
2. Place it in a relatively bright indoor environment with a temperature between 10°C to 30°C and little fluctuation. Keep it above 5°C in winter and below 35°C in the summer. Ensure proper ventilation and frequently spray water on the leaves. It can also be placed outdoors after Guyu and before Hanlu, slightly shaded in the summer. Keep it away from heat sources in dry indoor environments, especially in low temperatures.
3. Apply thin and frequent fertilization, often applying dilute cake fertilizer or alum fertilizer, and occasionally spraying 0.3% urea solution and 0.3% potassium dihydrogen phosphate solution. Avoid applying concentrated or raw fertilizers.
4. Actively prevent and treat diseases and pests. Use a 14.5% water-soluble powder formulation of multifunctional pesticide at 150 to 200 times dilution or a 20% wettable powder formulation of soil霸 at 500 times dilution for root irrigation, once every 20 days. Apply 3% furanadan granules, 5 to 10 grams per plant, once every 20 days to control pests. Spray 70% methyl thiophanate wettable powder at 1200 times dilution to control foliar diseases.
5. Prevent defoliation. Spray a cytokinin solution at 50 mg/kg of water, or a 0.01% Fultz 300 to 400 times dilution solution, once every 15 to 20 days. During the vigorous growing periods in spring and autumn, you can also spray a 15% multifunctional唑 wettable powder formulation at 300 to 500 times dilution once or twice. In dry or drought conditions, you can also spray a high-fat membrane emulsion at 200 times dilution. Before changing the environment or to strengthen the tree's vigor, you can use a 5ppm to 10ppm ABT3 root growth hormone solution for root irrigation.
6. Control defoliation. Once the banyan tree starts to defoliate, spray a 95% defoliant wettable powder formulation at 50,000 times dilution, or a 0.4% wettable powder formulation of plant cytokinin at 800 times dilution. In cases of sufficient fertilizer and water, you can also spray a gibberellin solution at 20 mg/kg of water to control defoliation, with severe cases requiring applications once or twice a week. At the same time, consider soil, fertilizer, water, and management comprehensively and apply targeted treatments.
