What medicine should I use for yellowing green radish leaves?
As a common indoor leaf-viewing plant, green radish suddenly turns yellow and always makes people worry. Faced with this situation, novices often fall into the misunderstanding of "what medicine to use." In fact, 90% of yellow leaf problems do not require medication, and the key is to find the crux, adjust and maintain it. Analysis of the root causes of green radish yellow leaves: Light imbalance: Direct exposure to strong light, the key to photosynthesis, will cause the leaves to burn and turn yellow, manifested as dry leaf tips accompanied by macula. Long-term lack of light causes the entire leaves to fall green and the new leaves to grow thin and long. It is recommended to move the plant 1.5 meters away from the window to ensure light scattering for 4 hours a day. Water management: The art of dry and wet cycle hydroponics of green radish can easily rot roots if the water level is too high. If the water in soil culture exceeds 24 hours, there will be oxygen deficiency. Judgment standard: Dry 2 cm under the soil surface before watering. If the roots are rotten, cut off the black roots, soak them in carbendazim and replace them with a new medium. Nutrient supply: The balance between fertilizer deficiency and fertilizer damage. New leaves are yellow and often lack iron, and old leaves are yellow first and often lack nitrogen. It is recommended to add 3 drops of special nutrient solution every month for hydroponics, and use slow-release fertilizer for soil cultivation in spring and autumn. Pay attention to dilute the concentration to 1/2 of the instructions to avoid salt accumulation. Advanced maintenance skills·Humidity maintenance: Maintain 50% humidity with a humidifier in winter·Temperature control: 18-28℃ is the best for growth, and heat preservation is required below 10℃·Leaf cleaning: Use beer diluent to wipe the leaf pores every month and adjust the system. Environmental parameters, usually new leaves can germinate in 2-3 weeks. If the yellow leaves continue to spread, it is recommended to check the soil pH value (preferably 5.5-6.5) or conduct pathogen testing.
