Can Dishui Guanyin be transplanted in autumn?
As a typical leaf-viewing plant, Dishui Guanyin is favored by green plant enthusiasts for its unique leaf shape. After entering autumn, many flower lovers began to consider changing pots and transplanting the plants, but the yellow leaf phenomenon that appeared after transplanting was confusing. This article will conduct an in-depth analysis of the feasibility of transplanting in autumn and propose systematic solutions to the yellow leaf problem. The best time window for transplanting Dishui Guanyin in autumn is the most suitable time window when the average daily temperature is stable at 20-25℃ from September to October. At this time, the plant is in an active growth period but has not yet entered dormancy, and the root system recovery ability is the strongest. Avoid continuous rainy weather and choose sunny morning operations with humidity below 70%. The optimization plan for substrate ratio recommends using a mixed substrate with peat soil: perlite: humus soil =4:3:3, and the pH value is controlled between 5.5 and 6.5. Add 5g of slow-release fertilizer granules per liter of soil to ensure slow-release of nutrients (G-Y). The three major inducements of yellow leaves after transplanting are analyzed. Light stress response. Newborn roots are sensitive to ultraviolet light. It is recommended to maintain them in a scattered light environment (light intensity ≤8000lux) for 2 weeks after transplanting, and use a sunshade net to filter 50% of direct light. Gradually increase the light after the new leaves unfold. Imbalanced water management After the first thorough irrigation of root-fixing water after transplanting, the substrate humidity should be maintained between 40% and 60%(can be monitored with a soil hygrometer). Using the dipping basin method to replenish water is more conducive to the roots to absorb water evenly and avoid stagnant water and rotten roots. About 30% of old leaves appear yellowing during the root damage and repair period, which is a normal metabolic phenomenon. Nutritional supplements can be achieved by spraying 0.1% ferrous sulfate solution on the leaves. Focus on observing the status of new buds. If the terminal buds continue to germinate, no excessive intervention is needed. The systematic maintenance plan will suspend fertilization within 30 days after transplanting, and apply 2000-fold diluted Huaduo No. 1 after new roots grow. Keep the temperature difference between day and night between 5-8℃, and the temperature at night is not lower than 15℃. Use 800 times carbendazim solution to irrigate roots every month to prevent diseases.
Through precise control of environmental parameters and scientific maintenance, the transplant survival rate can be increased to more than 90%. Remember the "Three No Principles for Slow Seedling Stage": Dishui Guanyin can be quickly restored to vitality without exposure to the sun, fertilization, and replacement positions.
